California Geologic Regions and Hazards: Follow-Up Presentation Created by the Natomas High School / Inderkum High School Science Lesson Study Team 2005

What 6 geologic hazards occur in California?  Earthquakes  Landslides  Volcanoes  Floods  Coastal Erosion  Tsunamis You should now be able to make general conclusions about the types of places where these hazards occur. Review: Let’s begin...

Where do earthquakes occur? What does the land look like in areas with earthquakes? EARTHQUAKES:

Earthquakes occur in the provinces near plate boundaries. Fault lines are evidence of earthquakes.

Where do landslides occur? What does the land look like in areas with landslides? LANDSLIDES:

Landslides occur in mountainous areas where loose soil or rock slides downhill. Landslides can also occur on gentle slopes after long periods of rainfall. Landslides are a hazard in provinces with mountain ranges.

Where do volcanoes occur? What does the land look like in areas with volcanoes? VOLCANOES:

Volcanoes occur in provinces offset from converging (or once converging) plate boundaries. Volcanoes often look like single steep mountains.

Where do floods occur? What does the land look like in areas with floods? FLOODS:

Floods occur in provinces with flat land, rivers, and abundant rainfall. Excessive rainfall can cause rivers to rise over their banks, leading to flooding.

Where does coastal erosion occur? What does the land look like in areas with coastal erosion? COASTAL EROSION:

Coastal erosion occurs in the provinces along the California coast. The beaches and cliffs slowly move inland as land is eroded by the ocean.

Where do tsunamis occur? What does the land look like in areas with tsunamis? TSUNAMIS:

Tsunamis could occur in any province along California’s coastline. Tsunamis are caused when earthquakes or landslides in the ocean floor uplift a large volume of water. Ocean Beach, San Francisco
