1. Chapter 10 Section 3 Earthquake Hazards Objectives: -Summarize earthquake hazards and the damage they can cause -Explain how safe building practices and earthquake prediction can prevent damage

2. Earthquake Hazards Aftershocks, fires, and tsunamis may cause damage after earthquakes

3. Ground Shaking and Foundation Failure Waves set in motion by earthquakes similar to the way a bell vibrates when struck Largest vibrations are side to side and cause buildings to collapse

4. Liquefaction Occurs when loose soil behaves like a liquid and causes the foundations of building to collapse. – What kind of waves? Be specific. Liquefaction animation of seattle harbour distruction

5. Aftershocks Smaller earthquakes after initial earthquake and further damages buildings

6. Tsunamis Underwater earthquakes and landslides sometimes cause huge ocean waves Tectonic Simulation Sumatra Simulation Sri Lanka Tsunami 2004

7. Seismic Gaps -Plotting earthquake foci from past earthquakes can reveal patterns in seismic activity. -Gaps may reveal places where stresses build.
