Effects of Earthquake bull Devastating effects of earthquakes due to failure of structure
Earthquake never kills
but damage of structures
during earthquake due to
incorrect or insufficient
design and
constructions kills 3
Effects of Earthquake bull Devastating effects of earthquakes due to failure of soil beneath
Buildings dilapidated because of failure of soil beneath
Structure is safe but
it has settled down
by huge amount
due to failure of
ground beneath

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Principal Types of Earthquake Damage
Liquefaction
Occurs in loose saturated sands
Grain structure collapses
Pore pressure increases
Effective stress decreases
Strength and stiffness decrease

Soil Liquefaction
Termed liquefaction the
strength of the soil reduced
often dramatically to the point
where it is unable to support
structures or remain stable

Earthquake Destruction Retaining Structure Failure
September 1999 Chi Chi Earthquake Taiwan
32
D Choudhury IIT Bombay India
Liquefied soil exerts higher pressure on retaining
wallswhich can cause them to tilt or slide
33
D Choudhury IIT Bombay India
Increased water pressure causes collapse of dams
34
Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse
eg 1989 Loma Prieta
1906 San Francisco
Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

D Choudhury IIT Bombay India
bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Liquefied soil exerts higher pressure on retaining
wallswhich can cause them to tilt or slide
33

Increased water pressure causes collapse of dams
34
Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

1906 San Francisco
Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis
37
D Choudhury IIT Bombay India
Tsunami Movement ~800 kmph in deep water
~350 kmph in medium depth water
~50 kmph in shallow water

38
D Choudhury IIT Bombay India
bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors

Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well
Earthen materials unreinforced concrete -- very vulnerable to
shaking

Liquefied soil exerts higher pressure on retaining
wallswhich can cause them to tilt or slide
33

Increased water pressure causes collapse of dams
34
Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse
eg 1989 Loma Prieta
1906 San Francisco
Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis
37
D Choudhury IIT Bombay India
Tsunami Movement ~800 kmph in deep water
~350 kmph in medium depth water
~50 kmph in shallow water
Tsunami

D Choudhury IIT Bombay India
bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Earthquake Destruction Fire

D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Damage due to Earthquakes
Earthquakes have varied effects including changes in
geologic features damage to man-made structures and
impact on human and animal life
Earthquake Damage depends on many factors
The size of the Earthquake
The distance from the focus of the earthquake
The properties of the materials at the site
The nature of the structures in the area
10
D Choudhury IIT Bombay India
Ground Shaking Frequency of shaking differs for different seismic waves
High frequency body waves shake low buildings more
Low frequency surface waves shake high buildings more
Intensity of shaking also depends on type of subsurface material
Unconsolidated materials amplify shaking more than rocks do
Buildings respond differently to shaking depending on construction styles materials
Wood -- more flexible holds up well

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

34
Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Liquefied soil exerts higher pressure on retaining
wallswhich can cause them to tilt or slide

Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire

D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Increased water pressure causes collapse of dams
34
Earthquake Destruction Lifelines
35

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse

Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

Earthquake Destruction Retaining Structure Failure
September 1999 Chi Chi Earthquake Taiwan
32
D Choudhury IIT Bombay India
Liquefied soil exerts higher pressure on retaining
wallswhich can cause them to tilt or slide
33
D Choudhury IIT Bombay India
Increased water pressure causes collapse of dams
34
Earthquake Destruction Lifelines
35
D Choudhury IIT Bombay India
Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse
eg 1989 Loma Prieta
1906 San Francisco
Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area
Earthquake Destruction Tsunamis

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

Earthquakes
sometimes cause fire
due to broken gas lines
contributing to the loss
of life and economy
The destruction of lifelines
and utilities make
impossible for firefighters to
reach fires started and
make the situation worse
eg 1989 Loma Prieta
1906 San Francisco
Earthquake Destruction Fire
36
D Choudhury IIT Bombay India
Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes

Tsunamis can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water
The water above the deformed area is displaced from its equilibrium
position Waves are formed as the displaced water mass which acts
under the influence of gravity attempts to regain its equilibrium
Tsunami travels at a speed that is related to the water depth - hence as
the water depth decreases the tsunami slows
The tsunamis energy flux which is dependent on both its wave speed
and wave height remains nearly constant
Consequently as the tsunamis speed diminishes as it travels into
shallower water its height grows Because of this effect a tsunami
imperceptible at sea may grow to be several meters or more in height
near the coast and can flood a vast area

bullGeomorphological changes are often caused by an
earthquake eg movements--either vertical or horizontal--
along geological fault traces the raising lowering and
tilting of the ground surface with related effects on the flow
of groundwater
bullAn earthquake produces a permanent displacement across
the fault
bullOnce a fault has been produced it is a weakness within
the rock and is the likely location for future earthquakes
bullAfter many earthquakes the total displacement on a large
fault may build up to many kilometers and the length of the
fault may propagate for hundreds of kilometers
