PAGE 63

7. Earthquake Damage Earthquakes can violently shake the ground
Surface ground cracking can occur
horizontal and vertical displacement of the ground are common

11. Earthquake Damage
However, movement of the earth rarely causes human injury or death
Most injuries result from:
Collapse of buildings/bridges
Falling objects
Flying glass

14. Earthquake Damage
Well constructed buildings made of heavy materials are more likely to withstand earthquake stress
Poorly built buildings will receive more damage

16. Liquefaction Saturated soil loses strength during an earthquake
Causes the ground to behave like a liquid
Some areas are very susceptible to liquefaction
Mostly below sea level or the water table
Areas built on bedrock do not experience liquefaction

19. Other Effects of Earthquakes
Landslides
Tsunamis
Caused by earthquakes in the ocean
