1. Californias Natural Hazards Volcanoes, Landslides, and Floods Presenters: Steven, Bryan, and Leo

2. - Earthquake triggers eruption - Pressure pushes magma up chamber - Volcano has an eruption

3. 5 potentially ( possibility ) active volcanoes Medicine Lake – Last activity 900 years ago Mount Shasta - 1786 Clear Lake – 10,000 years ago Lassen Peak - 1921 Long Valley – 1750s Coso – 2.5 million years ago

4. Seismic activity near volcanoes means, might have an eruption Get breathing masks and goggles Get out of the volcanoes area

6. A flood is the submerging ( to put underwater ) with water of a normally dry area. Floods are caused by many things, including rainstorms, slow water run-off, earthquakes, broken dams, underwater volcanic eruptions and tsunamis, or hurricanes.

7. floods are a natural consequence of stream flow in a continually changing environment caused by precipitation, which is caused by weather For example, heavy snow melts, water saturated ( unable to absorb or dissolve ) ground, unusually high tides, and drainage modifications ( to change ) when combined with heavy rain can lead to flooding

8. Next to rivers Where there is bad weather Areas below sea level

9. Natural weather disaster Most dangerous flood power of a flood with incredible speed and unpredictability. Dams and levees brake

10. Definition: Movement of slope Important Factor: Gravity

11. Major Types Creep ( to slip or gradually shift position) and Slump (to fall or sink suddenly.)

12. Explanation of Causes Construction Environmental Man-Made

13. Building Drainage pipes Reforestation (the action of renewing a forest) Careful Planning: When building near slopes and hazardous areas
