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 Clear Lake – 10,000 years ago Lassen Peak 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
