Unlike most natural disasters prediction of eathquake is very complex. It requires highly technical and sophisticated knowledge

gathered through scientific research. Due to the geological set up Bangladesh is under tremendous threat o f impending

devastating earthquake that could be generated from any of the regional active faults, located within the country and/or its

immediate vicinity. Rapidly growing of urban population, proliferation of high density unplanned urban agglomerations and,

improper designed and poorly constructed urban dwellings and infrastructure are having compounding effects on the urban

disaster vulnerability landscape to a great extent. In the backdrop of such a situation, it is a very timely initiative by Comprehensive

Disaster Management Programmee (CDMP II), a programme of Ministry of Disaster Management and Relief, to commission

earthquake risk assessment of major cities and paurashavas of Bangladesh and publishing this Atlas on "Seism ic Risk Assessment of

Bangladesh” compiling outputs of the assessments undertaken in this regard.

In Bangladesh our response towards any Imminent earthquake disaster mainly would be to increase our preparedness to a level so

that vulnerabilities of city dwellers and city infrastructure are reduced, and resilience of individuals, communities and above all local

government institutions are increased. These can be achieved through information sharing, awareness raising and capacity

building of relevant institutions.

CDMP's investment in generating scientific information on earthquake risk assessment had been substantial over the years and the

sheer amount of information generated had been tremendous. This Atlas, a compiled handy form of information generated, could

be used for ready references in decision making, planning and designing of risk reduction interventions, in scientific research, in city

and infrastructure management, and above all In the awareness building of city dwellers. All of these would lead to the building of

resilient urban space and also of resilient urban communities.

I would like to take this opportunity to thank both national and international professionals who worked relentlessly to publish this

very valuable document for the country

Empowered lives. Resilient nations.

M e s s a g e

Bangladesh’s rapid urbanization and steady progress towards middle-income-country status means that today, more than ever, the

resilience of the country's urban centers is vital to the continued well-being of its people and its continued development. It is

therefore with great pleasure that I welcome the publication of this atlas of seismic risk assessment in Bangladesh. This atlas

presents extensive and detailed data on earthquake hazards, risks and vulnerabilities of six major cities and municipalities. It is the

product of a risk research and assessment effort as-yet unparalleled in Bangladesh, providing a thorough and detailed knowledge

base for both decision-making and future research and updates.

Having not only enough, but also the right type of knowledge is crucial in securing the lives and livelihoods of people residing in

disaster-prone areas. The relative infrequency of earthquakes makes it hard for those who have not the lived experience or

specialist expertise to make the right decisions. Having a repository of data and knowledge should enable Bangladesh to not only

'build back better1 in the event of an earthquake - but to be able to build better in the first place. The results from the technical and

multi-disciplinary research - including studies of seismic fault-lines, geological and structural vulnerabilities - presented in this atlas

create a strong basis to develop key policy instruments and demonstrate the need for urgent implementation of these. I hope that

this atlas will be actively and frequently consulted by decision-makers, becoming a resource not only to disaster risk reduction

professionals, but also to local government officials, development professionals, planners, and researchers across the board.

The publication of this atlas is an achievement that would not have been possible without the support, participation and dedication

of the Ministry of Disaster Management and Relief, the Comprehensive Disaster Management Program team, and numerous

national and international experts and professionals.

I extend my heartfelt congratulations and thanks to all those who have contributed to the extensive process of gathering,

assessing and presenting the data in this atlas. The hard work of all the contributors will benefit decision-makers, professionals, and

most importantly - the people of Bangladesh for years to come.

M e s s a g e

It is really very pleasing to know that Comprehensive Disaster Management Programme (CDMP II), has taken initiative to publish an

Atlas on “Seismic Risk Assessment in Bangladesh” compiling results of the assessments undertaken in 6 major cities and

paurashavas of Bangladesh. This is in fact the first of its kind in Bangladesh produced from very comprehensive scientific studies

conducted over last four years.

Bangladesh is an earthquake prone country, due its proximity to major regional faults and underlying physical, social and economic

vulnerabilities. Risk of any impending earthquake is increasing for the urban centers of the country in every passing moment.

Taking appropriate preparedness measures to minimize the devastating effects of any impending earthquake is high on the agenda

of the Government of Bangladesh. However, in designing and implementing appropriate interventions on earthquake risk

reduction the necessity of having scientific information had been a long overdue. CDMP’s current initiative of publishing this atlas

therefore could be viewed as a right step towards a right direction.

Department of Disaster Management is one of the implementing arms of the Ministry of Disaster Management and Relief for

dealing with disaster management activities in Bangladesh. The department has a network of professionals working across the

country. This very important knowledge product will definitely help its professionals to take risk- informed decisions in their

everyday businesses. Besides, since DDM is the safe depository of disaster management related knowledge products and

documents, and, is the institutional memory for MoDMR, this valuable document will be an important inclusion which could be

used for a ready reference for the researchers and professionals.

I would encourage planners, development professionals and all concerned citizens to make best use of this atlas, so that, working

together we can make our cities and towns more resilient.

I express my heartfelt thanks to UNDP and other development partners for supporting CDMP II to conduct various high quality

studies, and specially, on earthquake risk assessment of 6 very vulnerable cities and paurashavas of Bangladesh and to publish this

very valuable Atlas.

Bangladesh is recognized as one of the most vulnerable countries of the world with regard to earthquake disaster due to its

geographical location, unabated and unplanned growth of urban settlements and infrastructure, and ever increasing urban

centers, located very close to the major active faults of the region to many folds.

Comprehensive Disaster Management Programme of Ministry of Disaster Management and Relief for the first time in the country

initiated comprehensive earthquake risk assessment during its phase I and continued the endeavor in phase II which is designed

and being implemented to reduce Urban Disaster Risks. A wide range of high quality scientific studies, including earthquake Hazard

Identification, Risk and Vulnerability Assessment, Risk Informed Landuse and Contingency Planning have been conducted by the

eminent national and international professionals, and well reputed agencies from home and abroad. The Atlas on "Seismic Risk

Assessment in Bangladesh" for 6 highly vulnerable cities/ paurashavas of Bangladesh is a consolidated output of all these efforts.

The Atlas has been developed with the intention o f assisting the policy makers, government officials, planners working in various

Ministries and Departments, academicians and researchers, house owners and developers to understand the earthquake

vulnerabilities of respective cities and paurashavas of the country, which would enable them to take risk informed decisions for

planning, designing and constructing urban infrastructure to reduce urban disaster risk to a great extent.

I firmly believe this Atlas would contribute immensely to the existing national knowledge pool On seismic hazard and related

vulnerabilities in Bangladesh. Besides, at practitioners’ level it would help in taking pro-active and targeted preparedness

initiatives, which are needed to achieve our much cherished dream of 'paradigm shift’ (from response to risk reduction) in disaster

management of the country.

I congratulate the professionals working in CDMP and other agencies for the sincere efforts they put together for publishing this

population. Current trend of urbanization is likely to increase earthquake vulnerability of the country, specifically to major urban

Comprehensive Disaster Management Programme II (CDMP II) acknowledges the contribution and wonderful spirit of cooperation

from all concerned strategic partners of CDMP II, particularly the Asian Disaster Preparedness Center (ADPC) for the successful

completion of the Atlas on “Seismic Risk Assessment in Bangladesh” describing the underlying threat, vulnerability, risk and

potential damage due to earthquake in Rajshahi, Rangpur city corporation and Bogra, Dinajpur, Mymensingh, and Tangail

Paurashava areas.

Special thanks are due to Mohammad Abdul Qayyum, Additional Secretary and the National Project Director of CDMP II, and, the

Urban Risk Reduction Team of CDMP II fo r their continuous following up, guidance and advice to ensure that the Atlas is o f a high

standard.

The Atlas development process was inspired by MoDMR. Continuous encouragement from UNDP had always been there. Technical

guidance from the Technical Advisory Croup, and contribution of a good number of national and international professionals, who

worked hard on the assignment, had been very instrumental in the development and publishing o f this Atlas, and, is appreciated.

CDMP II also recognizes the contribution and support from respective City Corporations and Paurashavas.

It is important to note that this Atlas is a living document, and, therefore, there is an expectation of further improvement in future

based on continuous research in many relevant disciplines.

It is now hoped and expected that intended end user of the atlas, the planners, engineers and developers, working in these six

cities will apply the knowledge in pursuit of a safer Bangladesh.

FROM E D IT O R ’S DESK

Urbanization has a great influence on the role disaster risk plays across the world. In the low and lower-middle income countries,

new urban development is increasingly more likely to occur on hazard prone land, namely, in floodplains and other low-lying areas,

along fault lines, and on steep slopes. In addition to settling in hazard prone areas, much of the building construction that occurs is

unregulated and unplanned, placing vulnerable populations, who settle on hazard prone land, at increased risk. Bangladesh is no

exception to these trends. Since the country is projected to experience rapid urbanization over the next several decades, it is

imperative for the policy makers and urban managers to plan for new urban developments with proper integration of disaster risk

information and pertinent risk management options into the urban planning and construction processes.

In recent years, Bangladesh has made significant progress in integrating flood risk management in both physical and social

development initiatives. There is however, increasing disaster risk from other impending hazards like Earthquakes. Since most of

the major cities in Bangladesh are growing rapidly without proper development control, the anticipated risk for the people and

infrastructure are gradually increasing. It is within this context the MoDMR along with the project partners of CDMP II saw the need

to develop a Seismic Risk Assessment for growing urban areas in Bangladesh. The project, Seismic Risk Assessment for the Six

Major Cities and Municipalities (i.e. Bogra, Dinajpur, Mymensingh, Rajshahi, Rangpur and Tangail) in Bangladesh is the first major

step towards identifying the potential earthquake risks for the major cities and devise possible planning and preparedness

initiatives for Disaster Risk Reduction (DRR).

Current initiative of Seismic Risk Assessment includes scientific assessments of seismic hazard that is looming on to these cities,

their vulnerabilities and risks, and above all, portraying of probable damage scenarios that could be experienced by these cities in

case of any impending earthquake. State of the Art technologies and scientific methodologies have been used to assess the

seismic hazard, vulnerabilities and risks of the cities and municipalities under the current project. In order to perform rigorous

seismic hazard analysis, all available information of historical earthquakes, tectonic environment, and instrumental seismic data

were gathered. In this study probabilistic assessment of two ground motion parameters, namely, horizontal Peak Ground

Acceleration (PGA) and Spectral Acceleration (SA) values at 0.2s and 1.0s with return periods of 43, 475, and 2475 years were

conducted. However, in this Atlas Scenario of 475 year return period, which is recommended as design base for National Building

Code, is presented. A good number of geotechnical and geophysical investigations were conducted for preparation o f Engineering

Geological Map, Soil Liquefaction maps for seismic hazard assessment and for damage and loss estimation. The investigations

include boreholes with SPT, PS Logging, M ASWand SSM, Microtremor Array and Single Microtremor assessments.

Damage and risk assessment for seismic hazard provide forecasts of damage and human and economic impacts that may result

from earthquake. Risk assessments of general building stock, essential facilities (hospitals, emergency operation centers, schools)

and lifelines (transportation and utility systems) using the HAZUS software package were conducted in this study. HAZUS was

developed by the United States' Federal Emergency Management Agency (FEMA) and National Institute of Building Sciences

(NIBS). It is a powerful risk assessment software program for analyzing potential losses from disasters on a regional basis. For risk

assessment analyses of the six City Corporation /Paurashava areas, defaults databases for the united States were replaced with

Bangladesh databases of the 6 cities/municipalities.

Reputed experts from both home and abroad, under the guidance of very well known and reverend group of professionals o f the

country in the Technical Advisory Croup for the project, worked relentlessly for years to generate scientific information required for

these assessments. Information generated were duly cross checked and scientifically verified.

This Atlas mainly presents the summary of the assessment findings of different components under the project. Main objective o f

the Atlas is to provide decision makers, and, city planners and managers with a compiled and handy set of information on the

current situation of the respective sectors in the cities in terms of vulnerability and risk to facilitate more informed and effective

development decision making.

This atlas contains altogether 5 Chapters. Unlike traditional atlases, a brief description on natural disasters in Bangladesh and a

general overview of disaster management of the country, discussed in chapter One would help readers to understand seismic risk

assessment and management in context of entire gamut of disaster management of the country. Geological setting, seismic hazard

and history of seismicity in Bangladesh-issues described in chapter Two would provide readers with a clear view of seismic

activities, their origins and hazard potentials in and around the country. Chapter Three, the major part of the atlas, presents seismic

vulnerability and risk assessment results of 6 cities/ municipalities along with a brief discussion on Initiatives taken so far on seismic

research in Bangladesh and methodology adopted in the current study for seismic hazard, vulnerability and risk assessment.

Chapter Four presents different preparedness initiatives, like preparation of Spatial Contingency Plan, simulation drill, capacity

building initiatives, so far been taken by the Government of Bangladesh. These would help raising awareness among local

government officials, change agents, CBOs and the communities on preparedness initiatives and devising right kind of

interventions to be taken for any impending seismic disaster. Chapter Five describes the way forward for future initiatives with

regard to seismic preparedness for the country.

These assessment results included in the Atlas are expected to help in reducing underlying risk factors for these cities, in promoting

the preparedness initiatives and enhancing emergency response capabilities of the key GOB organizations, humanitarian aid

agencies, development partners, decision makers, and above all, in increasing awareness o f city dwellers. The assessment results

are expected to be further integrated into the physical planning process of these cities in future, and would also provide useful

inputs into construction regulation and practices in order to develop risk resilient built environment. Along with this Atlas a good

number of different reports have been produced under the current initiative of CDMP ll. All these reports are available at e-library

of CDMP II and available at its website (www.dmic.org.bd/e-library). Maps presented in this document can be used as reference

only, for more detail, it is however, recommended to consult main reports.

This Atlas contains basic information about the hazards and disaster management system in Bangladesh. The main focus of the

atlas is the earthquake history of the country and the region, earthquake hazard in context of Bangladesh, and earthquake

vulnerability and risk with regard to papulation, infrastructure, building stock, and emergency facilities in six major cities /

Paurashavas (municipalities), including potential damage and loss estimation.

The main objective of the Atlas is to provide decision makers with information on the current situation of the respective sectors in

the cities in terms of vulnerability and risk- The study on seismic hazard assessment considered Probabilistic Assessment in terms of

PGA at 43, 475, and 2475 year return periods. Two scenarios have been developed for each of the return periods. However, in this

Atlas, scenarios of a 475 year return period- recommended as design base under the Building Code- is also presented. Different

types of exposure maps have been developed for all the cities included in the current assessment. Scenario maps (i.e., maps of

likely concrete & masonry building damage, liquefaction susceptibility, likely infrastructure damage maps etc.) have been

developed based on the risk assessment tools used in the assessment. Furthermore, the Atlas also contains a brief discussion of the

different initiatives for earthquake risk reduction and enhancing earthquake disaster preparedness implemented as part of

MoDMR’s CDMP II activities. Detailed methodology, discussions, results are available in the documents listed in Annex-2 Seismic

Risk Assessment: Available Research Documents in Bangladesh

This Atlas will assist the government departments in improving the Earthquake Risk Management system in their respective work

areas. It will also provide useful input to the formulation of policies and regulations to relevant sectors and their proper

implementation.

Over the past decades, urbanization in Bangladesh has flourished without proper guidance. As a result, many urban centers have

developed haphazardly. These urban centers are fast growing and influence the economic development of the country. It is

therefore essential to have a realistic understanding of the nature, severity and likely damage/loss that an earthquake could cause

in these urban areas. A strong earthquake affecting major urban centers may result in damage and destruction of massive

proportions, with disastrous consequences for the entire nation.

Considering this reality, the Comprehensive Disaster Management Programme (CDMP) being implemented by the Ministry of

Disaster Management and Relief (MoDMR) of the Government of Bangladesh (GoB) and supported by United Nations

Development Program (UNDP), European Union (EU), Norwegian Embassy, UKaid from the Department for International

Development (DFID), Swedish Sida and Australian Aid, is designed to strengthen the Bangladesh Disaster Management System,

and more specifically, to achieve a paradigm shift from reactive response to a proactive risk reduction culture. As part of this, the

Asian Disaster Preparedness Center (ADPC) has been given responsibility for conducting seismic risk assessments for several major

cities in Bangladesh. This Atlas presents the seismic risk assessment of Bogra, Dinajpur, Mymensingh, Rajshahi, Rangpur and Tangail

Municipal Areas. Chapter One describes the project background, and briefly discusses the natural disasters and disaster

management system in Bangladesh. Chapter Two presents a seismic hazard assessment of the country, followed in Chapter Three

by the seismic vulnerability, risk assessment methodology, different scenarios, and assessment results of different cities. The

results of risk assessment include: direct earthquake damage, induced earthquake damage, casualties, and economic losses* to the

components at risk. Chapter Four describes the preparedness initiatives implemented at different levels under this project. Chapter

Five describes the way forward for seismic preparedness for Bangladesh.

Due to its location Bangladesh has to receive and drain out huge volume of upstream waters. The mighty rivers Meghna, Padma

and Brhammaputra, originate in the Himalayas, make their way through Bangladesh, and drain in the Bay of Bengal. In the summer,

from May to August, the melting of glaciers in the Himalayas makes the rivers in Bangladesh live. The rainy season, which is strongly

influenced by monsoon wind from the South-West, also sets in at the same causing massive precipitation. The combined effect of

upstream flows, precipitation and terrestrial run-off result in flooding, causing water logging and prolonged flood almost every

Furthermore, rising sea levels are causing water level rise in the river, thereby accelerating the risk of flood and water logging. As

the elevation of the coastal plain of Bangladesh is only 3-5 meter from the mean sea level, a vast coastal area - approximately 18% of

the total landmass of the country - would be submerged by a 1 meter sea level rise, according to the IPCC 4th Assessment Report

(USA. IPCC, 2007). The main factors behind these assumptions are; a) the country has no defense mechanism for the protection of

coastal plain land, and b) the sea level will rise following the contour line. The problem of water logging might be more dangerous

than flooding. Already, many coastal places where sustainable drainage network system has not developed, are facing water

logging problems, and the intensity of problem is becoming more catastrophic day by day.

The entire coastal zone is prone to violent storms and tropical cyclones during pre monsoon and post-monsoon season. Therefore,

the Bangladesh coastal zone could be termed a geographical 'death trap’ due to its extreme vulnerability to cyclones and storm

surges. Since 1820, nearly one million people have been killed by cyclones in Bangladesh. Only 10 percent of the world's cyclones

develop in the Indian Ocean, but those 10 percent cause 85 percent of global cyclonic havoc (Gray, ig68).

The good news is that death tolls due to cyclones have decreased over the last decade, due to cyclone preparedness programs

such as the mobilization of volunteers in disseminating cyclone warnings and information and the building of cyclone shelters.

According to UNDP (2004) Bangladesh is among the Asian countries most highly prone to cyclonic disaster, as evident by the fact

that out of the 250 thousand cyclone-cause deaths worldwide between 1980 to 2000, 60 percent were in Bangladesh. Even though

N B A N G L A D E S H | 3

the Philippines is more vulnerable to cyclone than Bangladesh, the cyclonic death toll is 10 times higher in Bangladesh than in the

Philippines.

Extreme and non-extreme weather or climate events can affect vulnerability to future extreme events by affecting resilience,

coping capacity, and adaptive capacity (USA. IPCC, 2012). In particular, the cumulative effects of disasters at local or sub-national

levels can substantially affect livelihood options, resources, and the capacity of societies and communities to prepare fo r and

respond to future disasters.

Figure 3: Historical cyclonic storm track (Banglapedia, 2014)

A changing climate leads to changes in the frequency, intensity, spatial extent, duration, and timing o f extreme weather and

climate events, and can result in unprecedented extreme weather and climate events.

Landslides in the south eastern hilly region are another major hazard the country. These areas have a long history of

instability. Although written records of landslide incidents are very rare, they have been a hazard to people ever since the area wa

■first settled. Every year, especially in the rainy season, landslides take place In both natural and man-induced slopes. The cause is

often infiltration of water which makes the swelling soils more fluid. Major processes that cause landslides in Bangladesh are 1)

removal of lateral support through: (a) erosion by rivers, (b) previous slope movements such as slumps that create new slopes, (c)

human modifications of slopes such as cuts, pits, and canals; 2) the addition of weight to the slope through: (a) accumulation of

rain, (b) increase in vegetation, (c) construction of fill, (d) weight of buildings and other structures, (e) weight of water from

leaking pipelines, sewers, canals, and reservoirs; 3) earthquakes; 4) regional tilting; 5) removal of underlying support through: (a)

undercutting by rivers and waves; (b) swelling o f clays; and 6) anthropogenic activities as/hum cultivation.

Drought- a prolonged, continuous period of dry weather along with abnormal insufficient rainfall- is also another frequent disaster

in Bangladesh, especially in the north west region of the country. Drought occurs when evaporation and transpiration exceed the

amount of precipitation for a reasonable period. It causes the earth to parch, as well as a considerable hydrologic (water)

imbalance - resulting water shortages, dried-up wells, depletion of groundwater and soil moisture, stream flow reduction, crop

withering and failing, and scarcity in fodder for livestock- Drought is a major natural hazard facing those communities that are

directly dependent on rainfall for drinking water, crop production, and rearing of animals. Drought has become a recurrent natural

phenomenon of northwestern Bangladesh (i.e. Barind Tract) in recent decades. The Barind Tract covers most parts of the greater

Dinajpur, Rangpur, Pabna, Rajshahi, Bogra, Joypurhat and Naogaon districts of Rajshahi division. Rainfall is low in the Barind Tract

compared to other parts of the country. The average rainfall is about 1,971 mm, the majority of which occurs during the monsoon.

Rainfall varies aerially as wells as yearly. For instance, rainfall recorded in 1981 was about 1,738 mm, but in 1992 it was 798 mm. The

distribution of rainfall is rather variable from one place to another. Thus, the region is already known as draught prone area. The

average highest temperature of the Barind region ranges from 35°C to 25°C for the hottest season, and from 12°C to 15°C for the

coolest season. Generally this particular region of the country is rather hot and can be considered a semi-arid region. In summer,

the Rajshahi area, particularly Lalpur, may experience temperatures of about 45°C or even more on the hottest days. Meanwhile, in

the winter the temperatures may even fall to 5°C in some places of Dinajpur and Rangpur districts. So this older alluvium region

experiences two extremes that clearly contrast with the climatic condition of the rest of the country. Meteorologically drought can

be classified into three types: permanent drought - characterized by arid climate; seasonal drought - caused by irregularities in

recognized rainy and dry seasons; and contingent drought - caused by irregular rainfall. In Bangladesh, the last tw o types are more

prevalent.

Drought mostly affects Bangladesh in the pre-monsoon and post-monsoon periods. While drought did not affect the entire

country between 1949 and 1979, the percentage of drought affected areas were 31.63% in 1951, 46.54% in 1957, 37-47% in 1958,

22.39% in 1961> 18.42% in 1966, 42.48% in 1972 and 42.04% in 1979. During 1981 and 1982 draughts affected the production a f the

monsoon crops only. During the last 50 years, Bangladesh has suffered about 20 instances of drought conditions. Droughts in

northwestern Bangladesh led to a shortfall of rice production of 3.5 million tons in the 1990s. If other losses, such as, to other crops

(all rabi crops, sugarcane, wheat, etc.) as well as ta perennial agricultural resources, such as, bamboo, betel nut, fruits like litchi,

mango, jackfruit, banana etc. are considered, the loss is substantially much higher.


Figure 4: Meteorological Drought for Kharip and Rabi (Banglapedia, 2014)

Earthquake refers to the trembling or shaking movement of the earth's surface. Most earthquakes are minor tremors, while larger

earthquakes usually begin with slight tremors, rapidly take the form of one or more violent shocks, and end in vibrations of

gradually diminishing force, called aftershocks. An earthquake is a form of energy in wave motions, which originates in a limited

region and then spreads out In all directions from the source of disturbance. It usually lasts for a few seconds to a minute.

Earthquakes happen due to a number of reasons, which can be divided into two major categories: non-tectonic and tectonic.

Earthquakes are distributed unevenly on the globe. However, it has been observed that most of the destructive earthquakes

originate within two well-defined zones or belts, namely 'the circum-Pacific belt’ and 'the Mediterranean-Himalayan seismic belt’ .

Bangladesh is extremely vulnerable to seismic activity. Accurate historical information on earthquakes is very important In

evaluating the seismicity of Bangladesh, especially in combination with assessment of the geotectonic elements. Information on

earthquakes in and around Bangladesh is available for the last 250 years. The earthquake record suggests that since 1900, more

than 100 moderate to large earthquakes occurred in Bangladesh, out of which more than 65 events occurred after 1960. This brings

to light an increased frequency of earthquakes in the last 30 years. This increase in earthquake activity is an indication of fresh

tectonic activity or propagation of fractures from the adjacent seismic zones. Details about earthquake in Bangladesh are described

in Chapter 2.

Due to its geographic location and dense settlement pattern, Bangladesh has a long history of being affected by natural disasters.

It is estimated that between 1980 to 2008 the country faced damages of 16 Billion USD from about 200 disaster events. As a

developing country, Bangladesh had to depend very much on relief from donor agencies and foreign countries. After a devastating

flood in 1988, a national Flood Action Plan was initiated, marking the birth of a culture of disaster management and risk reduction.

A catastrophic cyclone in 1991 demonstrated the necessity of establishing institutional disaster management platforms in the

country, and consequently the Disaster Management Bureau (current DDM) was established in 1993. From the early 2000s, with a

view to shifting from the traditional relief and rehabilitation approach to the more holistic disaster risk reduction approach,

initiative was taken for a Comprehensive Disaster Management Program contributing to disaster preparedness at all levels of the

country. Currently, the Ministry of Disaster Management and Relief of the Government of Bangladesh is the responsible ministry

for coordinating national disaster management efforts across all agencies. The Ministry issued the Standing Orders on Disaster

(SOD) in January 1997 (updated in 2010) to guide and monitor disaster management activities in Bangladesh.

2 . 1 G e o l o g i c a l S e t t i n g s

Tectonically, Bangladesh lies on the northeastern Indian plate, near the edge of the Indian craton and at the junction of three

tectonic plates - the Indian plate, the Eurasian plate and the Burmese microplate. These form two boundaries where plates

converge- the India Eurasia plate boundary to the north forming the Himalaya Arc, and the India Burma plate boundary to the east

forming the Burma Arc. The Indian plate is moving at a rate of 6 cm per year in a northeast direction, and subducting under the

Eurasian and the Burmese plates in the north and east, at a rate of 45 mm per year and 35 mm per year, respectively (Sella et al.,

2002; Bilham, 2004; Akhter, 2010).

To the north, the collision between the Indian and Eurasian plates has created the spectacular Himalayan Mountains, bounded

along their southern flank by the Himalayan Frontal Thrust (HFT), along which continental lithosphere of the Indian plate under

thrusts the Eurasian plate. This great north dipping thrust fault runs more than 2,000 km from Pakistan to Assam and has produced

many large continental earthquakes over the past millennium, some greater than M 8. The 500-km long section just 60 km north of

Bangladesh, however, has not produced a great earthquake in the past several hundred years (Kumar et al. 2010).

The other major active tectonic belt of Bangladesh appears along the country's eastern side. The Arakan subduction-collision

system involves oblique convergence of the Indian and Burma plates. It has produced the N-S trending Indoburman range and a

broad belt of folds along the western edge of the Bay of Bengal (Curray, 2005; Wang and Sieh, 2013). These lie above a mega thrust

that dips moderately eastward beneath the Indoburman range but is nearly flat-lying beneath the folds. Beneath the 500-km long

fold belt the mega thrust is also referred to as a decollement, because it is parallel or nearly parallel to sediment bedding within the

Canges Brahmaputra delta. As we will describe below, many of the folds within the western 100 to 200 km of the fold belt appear

to be actively growing, which implies that the underlying decollement is relaying slip onto thrust faults beneath these folds as it

dies out westward toward a poorly defined deformation front.

2 . 2 S e i s m i c H a z a r d a n d B a n g l a d e s h

Bangladesh is located in the tectonically active Himalayan orogenic belt, which has developed through the collision among the

Indian, Arabian, and Eurasian plates over the last 30-40 million years (Ma), (Aitchinson et al.2007). Moderate to large earthquake

magnitudes are common in this region and will continue to occur as long as the tectonic deformation continues. Some of these

earthquakes cause serious damage to buildings and infrastructures through strong ground shaking and also, in some cases, faults

rupturing the ground surface. The destructive and deadly hazards associated with earthquakes pose a real and serious threat to the

lives of people, property damage, economic growth and development of the country. A proper understanding of the distribution

and level of seismic hazard throughout the country is therefore necessary. In order to perform rigorous seismic hazard analysis, all

available knowledge of the historical earthquakes, the tectonic environment, and instrumental seismic data are required to predict

the strong ground shaking of future earthquakes. However, until now, investigation of the seismic potential of Bangladesh's

tectonic elements has been in its infancy (GoB. CDMP, 2013). The main objective of this work is to determine appropriate

earthquake ground motion parameters for seismic mitigation, based on current existing data and most recent geological data

interpretation. These ground motion parameters include: horizontal Peak Ground Acceleration (PGA) and Spectral Acceleration

(SA) values at 0.2 and 1.0 s with the return periods of 43, 475, and 2475 years.

The study team has considered Probabilistic Seismic Hazard Assessment in terms of PGA at 43, 475, and 2475 year return periods

and Spectral Acceleration (SA) at 0.25 and 1.0s at 43,475, and 2475 year return periods. In general, at the short return period, i.e. 43

years, the observed seismicity in and around Bangladesh controls the hazard for most considered structural periods. However, at

long return period, i.e. 2,475 years, the seismic hazard of all structural period is controlled by major tectonic structures, and these

results confirm the importance of further study of active tectonic structures in Bangladesh. For the 475 year return period PGA

hazard map, the hazard is fairly well correlated with the seismicity pattern shown in figure 10a. The effect of major active tectonic

structures in and around Bangladesh, excepting that from area near Dauki fault, on seismic hazard is not clear on this m a p ..

Ground motion across Bangladesh (represented by PGA) is in the range of 0.1-0 .6g, corresponding to the 475 year return period

and in the range of 0 .1-1.o g, corresponding to the 2,475 year return period. The effect of the high-slip-rate of Duaki fault could be

observed as the largest seismic hazard zone in Bangladesh. From the PGA and SA at 0.2s and 1.0s at 475 and 2,475 year return

period for six cities (i.e. Bogra, Dinajpur, Mymensingh, Rajshahi, Rangpur and Tangail), are included in CDMP phase II. Out o f these

six cities, Bogra, Mymensingh, and Rangpur have by far the greatest seismic hazard. The estimated PGA value of o.5g at 2,475 year

return period is comparable to the seismically active region of the intermountain west in the United States (Petersen et al., 2008).

This is primarily due to its proximity to the potentially fast moving Duaki fault which augmented from high rate of background

seismicity. The seismic hazard of Rajshahi is the lowest at about o_4g at 2,475 year return period, largely because it is far removed

from the Dauki active fault and Arakan blind mega thrust. In addition, Rajshahi is the one of location in Bangladesh where previous

analysis based on instrumental seismicity - may underestimate what might be expected from the Martin and Szeliga’s (2010)

historical earthquake catalogue, where there are two events located with earthquake magnitude between 7.3 and 8.0 on 11

November 1842 and 22 June 1897, respectively.

Although in the recent past Bangladesh has not been affected by any large earthquakes, the evidence of large scale earthquakes in

the region serves as a reminder of the possibility of big earthquakes in the future. Past major earthquakes in and around

Bangladesh include the 1548 earthquake that hit the Sylhet and Chittagong regions, the 1642 earthquake in Sylhet District with

damage to building structures, 1762 earthquake hit most part of Bangladesh including Dhaka & Chittagong caused loss o f life and

properties, 1897 Known as the Great India Earthquake with a magnitude of 8.7 hit the region. This earthquake caused serious

damage to buildings in Sylhet town, where the death toll rose to 545. In Mymensingh, many public buildings, including the Justice

House, collapsed. Heavy damage was done to the bridges on the Dhaka - Mymensingh railway and traffic was suspended for about

a fortnight. The river communication of the district was seriously affected. Loss of life was not great, but loss of property was

estimated at five million Rupees. Rajshahi suffered severe shacks, especially on the eastern side, and 15 people died. In Dhaka,

damage to property was heavy. In Tippera, masonry buildings and old temples suffered a lot and the total damage was estimated

at Rs. 9,000. The 1918 earthquake known as the Srimangal Earthquake is occurred on 18 July with a magnitude o f 7. 6 Richter scale,

its epicenter located at Srimangal, Maulvi Bazar.

The 1997 Chittagong earthquake, or the 1997 Bandarban earthquake, occurred on November 21, 1997 at 11:23 UTC in the

Bangladesh-lndia-Myanmar border region. It had a magnitude of Mw 6.1 (USGS, 2014). The epicenter was located in southern

Mizoram, India. While no fatalities were reported in Mizoram, India, however, 23 people were killed when a 5-storey building

collapsed in Chittagong, Bangladesh (A5C, 2008).

An earthquake occurred on 22 July, 1999 at Maheshkhali Island with the epicenter in the same place, a magnitude o f 5.2. The

earthquake was severely felt around Maheshkhali Island and the adjoining sea. Houses cracked and in some cases collapsed.

The Borkol earthquake occurred in the early morning of 27 July 2003 at 5:18:17.96 am local time, killed three people, injured 25

people and damaged about 500 buildings in Chittagong and the Chittagong Hill Tracts. Power supply to some areas was cut as a

transformer exploded at the Modunaghat Grid Sub station in Hathazari, Chittagong. The epicenter was situated2i7 km southeast of

RISK ASSESSMENT INITIATIVESIN BANGLADESH

Recognizing the earthquake vulnerability and risk in Bangladesh, a number of initiatives have been taken by the Government,

research institutes, donor agencies, International NGOs and National NGOs regarding Earthquake Preparedness and Management-

Most of the initiated projects are focusing in three thematic areas like Hazard & Risk Assessment, Awareness & Capacity Building

and Formulation of Plan & Preparedness. Following is a brief overview of the activities initiated by different agencies in these

different areas of earthquake preparedness and management.

H a z a r d & R i s k A s s e s s m e n t a n d R e s e a r c h

Department of Disaster Management (DDM), under the ministry of Disaster Management and Relief, is the focal agency in

Bangladesh for Disaster Risk Reduction and Disaster Risk Management. Since its inception in 1993 DDM has taken several initiatives

for Disaster Management Activities. Currently DDM (2011-2015) is implementing a project named "Multi Hazard Risk and

Vulnerability Assessment and Mapping” for the whole country. This nationwide assessment will cover the hazards like flood,

earthquake, drought, cyclone, storm surge etc. The assessment would act as the guidance for the disaster preparedness initiatives

in Bangladesh. The hazard and vulnerability mapping will be updated with the course of time and will be useful for the emergency

preparedness guide.

The Geological Survey of Bangladesh (GSB), under Ministry of Energy and Mineral Resources of the Government of Bangladesh,

plays vital role in earthquake research across the country. The main activities of the organization are to deal with the technical and

scientific aspects of earthquake. As a part o f that, the GSB check the land formation change, changes in river courses, undulation in

land etc. immediately after any earthquake. Earthquake fault zones are also identified by the Geological Survey of Bangladesh as a

part of its regular activities.

As a part of earthquake preparedness, GSB has installed Earthquake accelerometer at 20 points across the country. The reading of

these stations is useful for building code revision in the context of different parts of the country. In the recent tim e, GSB has

conducted geological investigation at Purbachal and Jhilmil residential areas. These results of the investigation will be handed over

to the respective agency which can be used for building code implementation in these areas.

Comprehensive Disaster Management Programme (CDMP) under the ministry of Disaster Management and Relief has launched

major earthquake preparedness programs in Bangladesh. The initiatives started in 20d8 with the earthquake risk assessment of

Dhaka, Chittagong and Sylhet City Corporation areas. This earthquake assessment also identified the active faults across the

country that is the sources for major possible earthquake. CDMP II also initiated for (2012-2014) earthquake risk assessment,

training & awareness development and city, agency and ward level Contingency Plan preparation for the cities o f Bogra, Dinajpur,

Mymensingh, Rajshahi, Rangpur and Tangail.

Chittagong Hill Tracts Development Facilities (CHTDFj-UNDP is a special program for the three hill districts of Bangladesh. Under one

of the regional programs, named ECRRP, CHTDF-UNDP took the initiative to conduct earth hazard and risk assessment for the

paurashavas of Rangamati, Bandarban and Khagrachari. The project was implemented from 2009 to 201O- Under this initiative,

detailed base maps, seismic hazard maps, building and lifeline vulnerability assessments were made for the municipal towns of

Rahnagati, Bandarban and Khagrachari. During the implementation of the project, a number of professionals from these three

towns were also provided with training on earthquake risk assessment methodology and techniques.

Bangladesh University of Engineering and Technology (BUET) have had several earthquake preparedness and research studies over

the years. The research projects include Seismic Micro Zonation in Cox's Bazar, a School Safety program in Dhaka and organizing

trainings on doing earthquake research. Additionally, the Civil Engineering Department of the institute has enhanced its capacity

through earthquake research programs initiated over the years. Moreover, the Bangladesh Network for Urban Safety (BNUS) was

initiated by BUET with the collaboration from ICUS, Japan. BUET also has expertise in structural engineering, geotechnical

engineering, and preparation of seismic hazard maps and in seismic micro-zonation of urban areas in Bangladesh. It has already

established the National Centre for Earthquake Engineering (NCEE) in 2002. BUET is currently overseeing a seismic instrumentation

project for a five kilometer long bridge (Jamuna multipurpose bridge, Bangladesh). It has also procured sixty SMAs from USGS

recently. A two year linkage project with Virginia Polytech Institute and State University, USA, on the topic of the seismic

vulnerability of Bangladesh, has been established.

The Earth observatory under the Department of Geology, University of Dhaka (established in 2003) is working with scientific

research on geological setup and tectonic setting. Currently, the center has 23 GPS units to monitor the 3D movement of the earth

crust. Active fault study and mapping is the one of the primary subjects the center wishes tD emphasize in its activities in the near

future-

The seismic risk assessment describes the scale and the extent of damage and disruption that may result from potential

earthquakes. Damage and risk assessments for seismic hazards provide forecasts of damage, and human and economic impacts

that may result from earthquake. The scope of work covers the risk assessment of the general building stock, essential facilities

(hospitals, emergency operation centers, schools) and lifelines (transportation and utility systems). For CDMP-I & CDMP II the risk

assessment has been executed using the HAZUS software package. HAZUS was developed by the United States’ Federal

Emergency Management Agency (FEMA) and the National Institute of Building Sciences (NIBS). It is a powerful risk assessment

software program for analy2ing potential losses from disasters on a regional basis. This risk assessment scheme can be used

primarily by local, regional, and central government officials to plan and stimulate efforts to reduce risks from earthquakes and to

prepare for emergency response and recovery.

HAZUS operates through a Geographic Information System (GIS) application i.e. the ESRI ArcGIS platform. For risk assessment

analyses of the nine city corporation areas and paurashavas, defaults databases for the United States have been replaced with

Bangladesh databases of the nine cities/towns. Ground shaking is characterized quantitatively, using peak ground accelerations

and spectral response accelerations. HAZUS methodology aggregates the general building stocks on a cluster basis, but is site-

specific for essential facilities and lifelines. The transportation and utility lifeline losses are combined in one package with losses

associated with the general building stock and essential facilities.

The framework of the HAZUS risk assessment methodology includes six major modules shown in Figure 11. As indicated by the

arrows in the figure, the modules are interdependent, with the output of one module acting as input to another. Explanation of

every module is given below.

Figure 11: Flowchart of HAZUS Earthquake Risk Assessment Methodology

1. Potential Earth Sc ie nce Hazards (PESH)

The PESH module estimates ground motion and ground failure. Ground motion demands such as Peak Ground Acceleration (PGA)

and spectral acceleration are estimated based on earthquake source parameters, attenuation relations and geological data.

Ground failure caused by landslides, liquefaction and surface fault rupture are quantified by Permanent Ground Deformation (PGD).

This PGD is determined based on topographic data, geological data and ground water depth.

2. Inventory

The inventory contains tools for describing the physical infrastructure and demographics of the study areas. It uses standardized

classification systems for the groups of components at risk: (a) general building stock, (b) essential facilities, (c) transportation

system components, and (d) utility system components. These groups are defined to address distinct inventory and modeling

characteristics. An extensive amount of GIS database is utilized to develop dataset for each these groups.

The general building stock is classified by occupancy (residential, commercial, etc.) and by model building type (structural system

and material, height). Characteristic relationships between occupancy and structure types are developed based on building survey

data. Population data is derived from the average of building occupants per unit building, which is obtained from the building

survey. Estimates for building exposure are based on for building replacement costs (dollars per square foot) for each model

building type and occupancy class that has been modified to Bangladesh cost. The dataset of essential facilities lifelines is

developed from the GIS database and secondary sources (service provider authority), clarified and verified through the field survey.

3. Direct Physical Damage

This module provides damage estimates in terms o f probabilities of occurrence for specific damage states given in a specified level

of ground motion and ground failure. Estimates also include loss of function to essential facilities and lifelines and the anticipated

service outages for potable water and electric power.

For buildings, the capacity-demand spectrum method as implied by HAZUS is utilized for the estimation of seismic demand. The

estimated seismic demand is, thus, used to determine the probability of being in a particular damage state through fragility

functions. However, the seismic performance of buildings in Bangladesh is different from that of United States. As a result, a new

set of building capacity spectrum and fragility functions were developed based on the field survey data and comprehensive

numerical analyses.

For both essential facilities and general building stock, damage state probabilities are determined for each facility or structural

class. Damage is expressed in terms of probabilities of occurrence of specific damage states, given specific levels of ground motion

and ground failure. Five damage states are identified - none, slight, moderate, extensive and complete.

For lifeline components, the methodology focuses on estimating damage and restoration times for every system of transportation

(highway, railway, bus, and ferry) and utility (potable water, waste water, natural gas, electric power, communication). Overall

fragility curves for a system are evaluated, using fault tree logic to combine components fragility curves. The hazard is typically

represented by Peak Ground Acceleration (PGA) and Permanent Ground Deformation (PGD). Utilizing overall fragility curves,

damage state probabilities are calculated for the lifeline components. Restoration times are evaluated from very simplified rules,

relating to degree of damage and size of component.

I 18

4 . Induced Physical Damage

Once direct physical damage has been calculated, induced damage can be evaluated. Induced damage is defined as the secondary

consequences of a natural hazard other than damage due to the primary hazard (earthquake) that led to initial losses. Here, the

methodology calculates damage due to fire fallowing an earthquake and tonnage of debris generation. For estimation of the

impacts from the fires that follow an earthquake, HAZUS methodology utilizes Monte Carlo simulation techniques to assess the

potential impacts. It separates the module into 3 major elements: fire ignition, spread, and suppression. The number of fires ignited

is estimated from the size and type of building inventory, and the ground motion to which it is subjected. Spread is calculated as a

function of the density of the construction, the presence of wind, fire breaks (e.g. lakes, wide streets) and low fuel areas (e.g.

parks, cemeteries). Suppression is calculated as a function of the available firefighting capabilities. The spread and suppression

modules use a damage and loss function calculated from the essential facilities and lifelines modules to determine the response

capabilities and effectiveness of the fire-fighting personnel. For debris, HAZUS methodology estimates 2 different types of debris.

The first type is debris that fall in large pieces like steel members or reinforced concrete elements, which require special treatment

to break into smaller pieces before they are hauled away. The second type is smaller debris more easily moved with bulldozers,

such as brick, wood, glass, building contents, etc.

5. D irect Eco no m ic/So cia l Losses

Both direct and induced damage can lead to direct losses. There are 2 types of losses evaluated in the methodology: economic and

social losses. The economic losses quantify the cost of repair and replacement of structures and lifeline systems that are damaged

as a consequence of the earthquake. Structural and non-structural damage, as well as losses to contents inside buildings are

included. To compute the direct economic losses, damage information from the direct damage module is combined with economic

data of the study area, particularly construction/replacement cost of buildings and lifeline systems. Social losses are quantified in

terms of casualties. To quantify the casualties, HAZUS methodology combines the output from the direct damage module with

building inventory and population data. Estimations are carried out for two times of a day: 2:OOPM (day time) and 2:00AM (night

time).

6. Indirect Econo m ic Losses

This module assesses the broad and long-term implications of the direct impacts (direct damage and losses) mentioned before.

Examples of indirect economic impacts are changes in employment and personal income. This module is not included in this work

due to a lack of complete data of income and employment.

Spatial databases have been developed for the study cities and have been used as base maps to assist the hazard and vulnerability

assessments. All important physical features of these cities are considered during the database development. Based upon the

availability of existing data and information on the respective cities, an appropriate methodology was developed to acquire missing

information by conducting physical feature surveys and attribute information collection.

Figure 12: Flow-chart of Base Map Development Process

For preparation of a base map, Satellite (Quickbird) images were collected. Ground Control Points for geo-referencing were

selected at suitable locations in the image. Established bench marks like SOB, PWD, BWDB, and JICA were used as referencing point

to do geo referencing. RTK-GPS and Total station were used for image geo-referencing. After geo-referencing of the image,

physical features like road alignment, building outline, water body boundary, river boundary etc. were digitized. After completion

of digitization, maps were printed for field verification. During field verification, a preset list of items was followed to collect

attribute information against each of the digitized features. After completion of attribute information collection and feature

verification, collected information had been added against the each surveyed features and base map was prepared for use. The

steps followed during base map preparation are given in detail below.

To properly assess the seismic vulnerability of existing building stock, it is necessary to know the building structural type, the

building occupancy class, the number of building occupants during the day and the night, the total floor area, the number of

stories, the cost of the building and its contents inside, the seismic vulnerability characteristics of building, etc.

To acquire the missing information, it is not necessary to survey each and every building in each of the cities— which is impossible

under the scope of budget and time frame. Instead, a series of well-designed comprehensive building surveys have been carried

out in this study. The surveys were classified into 3 levels: Level-01, level-02, and level-03 surveys.

Level 01: B uild ing Survey

In the level 01 building survey, sidewalk and questionnaire surveys were carried out. The average time required for this survey by a

2-member team was about 8-10 minutes for one building. The building attributes collected at this survey level were:

Number of stories; Occupancy class; Structural type; Number of occupants during the day and the night (Based on no. of

apartments); Age of the building(range); Presence of soft story (yes/no); Presence of heavy overhangs (yes/no); Shape of the

building in plan view (rectangular, narrow rectangular, irregular); Shape of the building in elevation view (regular, setback, and

narrow tall); Pounding possibility (yes/no); Building in slope land (yes/no); Visible ground settlement (yes/no); Presence o f short

columns (yes/no); Visible physical condition (poor/average/good)

Table 2 shows the list of number and types of buildings surveyed in the six cities.

Level 02: B ui ld ing Survey

About 10 percent of the level 01 surveyed buildings were selected for the Level 02 survey on a random basis. In addition to the

attributes acquired in the Level-1 survey, measurements of the building ground floor were taken. A sketch of the building plan at

the ground story was made, and the dimensions of columns, concrete and masonry walls were measured. The main objective of

this survey was to acquire more detailed information for more in-depth seismic vulnerability assessment of typical buildings. It

took, on average, about two and a half hours for a 2-member team to complete the Level 02 survey on one building.

For concrete buildings, the building attributes acquired during the Level-2 survey are:

• Torsional irregularity (non-rectangular shape, unsymmetrical infill, unsymmetrical shear wall)

• Short column (less than 25% of floor height, 25-50% of floor height, more than 50% of floor height)

• Diaphragm discontinuity (mezzanine floor, floor opening)

• Slab system (cast insitu, pre-cast)

• Key dimensions (plan dimensions, typical column size, no. of bays, span length, shear wall dimensions)

For masonry buildings, the building attributes acquired during the Level 02 survey are:

• Wall Thickness

• Maximum unsupported length of wall

• Corner separation (yes/no)

• Anchorage of wall to floor (yes/no)

• Anchorage of roof with wall (yes/no)

• Wall to wall anchorage (yes/no)

• Bracing of flexible floor/roof (yes/no)

• Existence of gable wall (yes/no)

• Horizontal band (yes/no)

• Vertical post (yes/no)

Level 03: B uild ing Survey

For dynamic measurement, level 03 surveys were conducted on few selected buildings in three of the cities. The main objective of

this survey was to understand the behavior of different types of buildings during earthquake. For dynamic measurement of RCC

Buildings, Micro tremor, Schmidt Hammer, Ferro Scanner and Vibration shaker were used. For masonry buildings, a shear strength

test of the binding mortar of masonry walls was conducted using a Hydraulic Jack with Deflection Meter.

Geotechnical and Ge ophysical Investigations

A number of geotechnical and geophysical investigations were conducted for preparation of engineering geological maps, soil

liquefaction maps for seismic hazard assessment, and for damage and loss estimation. The investigations included boreholes with

SPT, PS Logging, MASW and S5M, Microtremor Array and Single Microtremor. Table 3 gives a brief description on the number and

types of geotechnical and geophysical investigations conducted for the assessments;

The number of tests conducted had been determined depending on the surface geology (geomorphology) of the city. As a sample

case, the Mymensingh town example has been provided in the following figure. The number of the tests was set in such a fashion

that each of the geomorphic unit contains an adequate number of tests for the analysis.

All tests were conducted to measure the shear wave velocities at 30 m depth VS30 at the specific sites, which was utilized to

comprehend the soil characteristics of the site. Peak Ground Acceleration at bed rock level was calculated from the source

characteristics as well as the attenuation characteristics. Table 4 shows the empirical relationship between SPT N value and VS30.

The PGA will be amplified or de-amplified depending on the soil under the site. For the cities, the average shear wave velocities

were calculated to illustrate the soil classification as shown in table 5. The soil has been classified according to table 5 as follows.

For most of the cities under the study, the soil class was either D or E, which corresponds to soft and very soft soil.

Earthquake hazard risks need to be addressed in fo u r phases: m itigation, preparedness, e m erge ncy response and re co very.

H o w eve r, an Earthquake C o n tin ge n cy Plan only addresses th e em ergency response m anag em ent. Th e need fo r a com prehensive

geo-hazard risk reduction “ C ontinge ncy Planning” strategy th at is linked to an easy im plem entation fram e w o rk has been felt fo r

quite som e tim e n o w . It is therefore extrem ely im portant to anticipate, as best as possible, p robable earthquake threats in th e

earthquake em ergencies.

A s p a rt of th e Preparedness initiative, a C ontingency Plan focusing an earthquake hazard has been prepared fo r different level f a r

the study cities. In C D M P I, scenario based C ontingency Plans w e re prepared fo r National Level; C ity Level fo r th e c ity corp oratio ns

M o re o ve r, th e m aps developed u n de r th is study will be useful fo r d e ve lo p m e nt co ntro l to reduce earthquake risk in th e respective

cities and countries as a w hole . T h e significant findings fro m th e study are as follow ings:

« In general, at short re turn period, i.e. 43 years, th e observed

seismicity in and around Bangladesh controls the hazard fo r

m ost considered structural periods.

• G rou nd m otion across Bangladesh represented by PGA is in

th e range of 0 .1 -0 .6g, co rre sp o n d in g to th e 475-year return

period and in th e range o f 0 .1-1.0 g , co rrespo nding to the

2,475-year return period.

• Th e effect of high-slip-rate of Duaki fault could be observed as

th e largest seismic hazard in Bangladesh.

Th e G o v ern m en t o f Bangladesh and respective Paurashavas should take

th e initiative to incorpo ra te disaster risk reduction into th e urban

deve lo p m e nt planning m etho dologies in all o f the relevant sectors and

relevant levels. Th e im plem entation of these guidelines in risk

assessment and incorpo ratio n of hazard and risk inform ation into spatial

planning should be m andatory.

T h e respective Paurashavas and C ity C orpo rations involved in this study should continue using and u pdate th e database

periodically. This will be helpful fo r th e city authorities fo r initiating preparedness efforts fo r th e c ity dwellers.

Th e GIS database and m aps w hich have been used to generate the

seismic hazard, vulnerability and risk m aps in this Atlas should be k ept on

a w e b server and should be shared and updated b y th e respective

agencies. A p a rt fro m this, local agencies should set up a data bank on

Spatial Data Infrastructure, and define specific data fo rm ats and

standards fo r collecting, sto ring, updating th e database fo r fu rther

Dam age to infrastructure after an earthquake is a m a jo r loss trigger. O n e of the consequences o f such dam age is fire fa llo w in g a

seismic event. Fires often associated w ith broken electrical and gas lines, gas is set free as gas lines are broken and a single spark

can th erefore trigger an inferno. T o com plicate th ings, w a te r lines are broken and so there is n o w a te r to extinguish the fire,

earthquake can not only trigger a fire by releasing com bustible m aterial, bu t also b y im pairing passive or active firefighting systems.

A n effect o f seismic activity, such as an earthquake, w h e re the grou nd becom es very soft due t o th e shaking, and acts like a liquid,

earth ’s surface and on hum ans and th eir structures. Several scales exist, b u t th e ones m ost co m m o n ly used are th e M odified

A n earthquake w hose focus is located b e tw een 70 to 300 kilom eters fro m th e earth’s surface. Earthqu a ke-rep ort.com differs fro m

th e official notification calling earthquakes w ith a d e pth of m ore th an 40 to 00 km as "In te rm e d ia te ". Th is is m ainly because o f th e

Th e transform ation o f a granular material fro m a solid state into a liquefied state as a consequence o f increased p ore w a te r

pressures and reduced effective stress. In engineering seism ology, it refers to the loss o f soil strength as a result o f an increase in

pore pressure due to gro u n d m o tio n . Th is e ffect can be caused by earthquake shaking.

Soil liquefaction

Shaking and tilting causes

some structures to fail.

Loosely packed grainsof soil are held together by friction. Pore spaces

are filled with water.

Shaking destabilizes the soil by increasing the space between grains. With its structure lost,

the soil flows like a liquid.

Buildinc and sinks as SOif Stability

declines.

Figure; 23; Soil Liquefaction


Liquefaction occurs in saturated soils - th at is, soils in w hich the space b e tw een individual particles is co m plete ly filled w ith w a te r.

This w a te r exerts a pressure on th e soil particles th at influences h o w tigh tly th e particles them selves are pressed to ge th er. P rior to

an earthquake, th e w a te r pressure is relatively lo w . H o w ever, earthquake shaking can cause the w a te r pressure to increase t o th e

point w h e re th e soil particles can readily m ove w ith respect to each othe r.

W h e n liquefaction occurs, th e strength o f the soil decreases and, th e ability of a soil deposit to s u p p o rt fo undations fo r buildings

and bridges are reduced, as seen in th e im age belo w .

L o c k e d F a u lt

A locked fau lt is a fault th at is not slipping because frictional resistance on th e fault is greater than th e shear stress across th e fault.

Such faults m ay store strain fo r extended periods, w hich is eventually released in an earthquake w h e n th e frictional resistance is

overco m e. A locked fault condition contrasts w ith fault-creep conditions and an unlocked fault.

M a g n i t u d e

T h e m agnitude is a n u m b e r th at characterizes th e relative size of an earthquake. M agnitude is based o n m e a su rem ent o f th e

m axim um m otion recorded b y a seism ograph (som etim es fo r earthquake w aves of a particular freq u e n cy), co rrecte d fo r

attenuation to a standardized distance. Several scales have been defined, b u t th e m ost c o m m o n ly used are (1 ) local m agnitu de

(M L ), co m m o n ly referred to as Richter m agnitude, (2 ) surface -w ave m agnitu de (M s ), (3 ) bod y-w a ve m agnitude (M b ), and ( 4 )

m o m e n t m agnitude (M w ). M L, M s and M b have limited range and applicability and do not satisfactorily m easure th e size o f th e

largest earthquakes- Th e m o m e n t m agnitude (M w ) scale, based on th e co nce p t of seismic m o m e n t, is u n iform ly applicable t o all

sizes of earthquakes b u t is m ore difficult to co m pu te than th e o th e r types. In principal, all m agnitu de scales could be <

calibrated to yield the sam e value fo r any given earthquake, bu t this expectation has pro ve n to be only a pproxim ate ly true,

the need to specify th e m agnitu de type as well as its value. A n increase o f one unit o f m agnitude represents a io -fo ld increase in

w ave am plitude on a seism ogram o r approxim ately a 30-fold increase in the energy released. In o th e r w o rd s, a m agnitu de 6.7

earthquake releases o ver 900 tim es (3 0 tim es 3 0 ) th e energy o f a 4.7 earthquake - o r it takes a b o u t 9 0 0 m agnitude 4.7

earthquakes to equal the energy released in a single 6.7 earthquake! Th e re is neither beginning n o r end to this scale.

H o w eve r, rack m echanics seem to preclude earthquakes sm aller than a bou t 1 o r larger than a b o u t 9 .5 . A m a gnitu de -1.0 e vent

releases a b ou t 900 tim es less energy th an a m agnitude 1.0 quake. Except in special circum stances, earthquakes b e lo w m agnitu de

2.5 are not generally felt b y hum ans.

P-waves are a type o f bo d y w a ve th a t is th e first w a ve to arrive to th e seism ograph, and is called seismic w aves in seism ology. It can

travel th ro u g h a co ntinu u m . T h e co ntinu u m is m ade up of gases (as sound w a ve s), liquids, o r solids, including th e Earth . P-waves

can be pro du ced by earthquakes and recorded by seism ographs. The nam e P -w ave is often said to s tand e ither fo r p rim ary w a ve , as

it has the highest velocity and is th erefore th e firs t to be felt; o r pressure w ave, as it is fo rm e d fro m alternating com pressions and

Th e Earth’s ro ck y o u ter crust solidified billions years ago. This crust is n o t a solid shell; it is broken u p into huge th ic k plates. These

relatively large rigid segm ents o f th e Earth’s lithosphere m ove in relation to oth e r p lates o v e r th e a sthenosphere.

A th eo ry supported by a w ide range of evidence th at considers th e Earth’s crust and u pp e r m antle to be c o m p o se d o f several large,

th in, relatively rigid plates. Th e tem peratu re at the centre o f th e earth is as high 2500° c, w hile th e u pp e r surface is 25°c. Th e re is

also a huge a m o u n t o f pressure in th e inner m antle. This huge tem p eratu re and pressure causes th e semiliquid material o f inner

m antle to m o v e regularly. Th is causes th e plates to m o ve w ith respect to one another, and faults are cre ated. Several styles o f

faults bound th e plates, including th ru st faults a long w hich plate material is subducted o r co nsum ed in th e m antle, oceanic

spreading ridges a lo ng w hich n e w crustal material is pro du ced, and transfo rm faults th at a ccom m o date horizontal slip (strike slip)

A secondary w ave is the second type of body w ave oth e r than P-wave th at arrives in seism ograph. It is called secondary w ave

because it arrives later than the P-wave, as it m oves s lo w er in the rock. It is also called shear o r transverse w a ve , as it m oves

perpendicular to th e direction of w ave pro pagatio n. Unlike P-wave, the Secondary w ave can travel o n ly th ro u gh th e solid material

and are not able to pass th ro u g h liquids.

Seismic hazard refers to the stu d y o f expected earthquake grou nd m otions at the earth's surface, and its likely effects o n existing

natural conditions and m an-m ade structures fo r public safety considerations; th e results o f such studies are published as seismic

hazard maps, which identify the relative m otion of different areas on a local, regional o r national basis. W ith hazards th us

determined, their risks are assessed and included in such areas as building codes for standard buildings, designing larger buildings

and infrastructure projects, land use planning and determining insurance rates.

S e is m ic W a v e s

Seismic waves are the result of an earthquake, explosion or volcano where sudden release of energy burst out in form of waves.

During the energy release different type of seismic waves are created. There are body waves (P-wave and S-wave) which travel

through the interior of the earth, and there are surface waves which travel through the surface of the earth.

S e is m ic ity

The geographic and historical distribution of earthquakes. A term introduced by Gutenberg and Richter to describe quantitatively

the space, time, and magnitude distribution of earthquake occurrences. Seismicity within a specific source zone or region is usually

quantified in terms of a Gutenberg-Richter relationship.

S h a llo w E a rth q u a k e

An earthquake whose focus is located within 70 kilometers of the earth’s surface. Earthquake - report.com differs from the official

notification calling earthquakes with a depth up to 40 km as “ Shallow” . This is mainly because of the possible damaging impact of

these earthquakes.

It 1s the shallow earthquake that are the most devastating, and they contribute about the three-quarters of the total energy

released in the earthquake throughout the world.

S p e c tra l A c c e le ra t io n

Spectral acceleration (S A ) is a unit measured in g (the acceleration due to Earth's gravity, equivalent to g-force) that describes the

maximum acceleration in an earthquake on an object (example structure) specifically a damped, harmonic oscillator moving in one

physical dimension. This can be measured at (o r specified fo r) different oscillation frequencies and with different degrees of

damping, although 5% damping is commonly applied.

S u rfa c e F a u lt in g

Displacement that reaches the Earth’s surface during slip along a fault. Commonly accompanies moderate and large earthquakes

having focal depths less than 20 km. Surface faulting also may accompany aseismic tectonic creep or natural or man-induced

subsidence.
