How Earthquakes Cause Damage

 * earthquakes can cause a lot of damage
 * landslides
 * avalanches
 * tsunamis

Local soil conditions

 * solid rock shakes less
 * sandy soil shakes more

Liquefaction

 * can cause landslides
 * the 1964 Anchorage earthquake

Aftershocks

 * an earthquake that occurs after a larger earthquake in the same area

 * most people get injured or die from buildings
 * must make stronger and safer building

Choice of Location

 * Do not live near or on
 * steep slopes
 * can cause landslides during earthquakes
 * filled land
 * can shake dangerously during earthquakes
 * earthquake faults
 * will also shake very dangerously during earthquakes

Construction Methods

 * base-isolated buildings
 * a building made to decrease the amount of energy that reaches the building during an earthquake

Protecting Yourself During and Earthquake

 * hide under a strong table or desk
 * hold on to it so it doesn't move
 * if there isn't any table or desk sit against an inner wall
 * cover your head and neck with arms
