1. Earthquake Safety Chapter 6 Section 4

2. How Earthquakes Cause Damage Shaking –Avalanches, landslides –Destroy buildings, bridges, utility poles, gas lines, water mains The severity of the shaking is determined by the soil.

3. How Earthquakes Cause Damage Liquefaction –Violent shaking turns loose soft soil into mud –Ground that gives way can cause buildings to sink and pull apart

4. How Earthquakes Cause Damage Aftershocks –Can topple weakened buildings –Can occur hours, days or weeks later

5. How Earthquakes Cause Damage Tsunami –Ocean floor that pushes on water can form a giant wave that moves out from the epicenter

6. Earthquake safety Drop, cover and hold Indoors –Get under sturdy table or desk –Crouch near an inner wall –Cover your head and neck –Avoid windows, mirrors, things that can topple –prepare an earthquake kit (ahead of time)

7. Earthquake safety Outdoors –Get to an open area away from power lines and trees –Sit
