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

Lateral spreading in the soil beneath embankment causes the

embankment to be pulled apart producing the large crack down the

center of the road

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

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

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

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

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

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

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

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

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

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

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

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

impossible for firefighters to

reach fires started and

make the situation worse

eg 1989 Loma Prieta

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

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

Liquefied soil exerts higher pressure on retaining

wallswhich can cause them to tilt or slide

33

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Earthquakes

sometimes cause fire

due to broken gas lines

contributing to the loss

of life and economy

The destruction of lifelines

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

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

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
