Earthquake Mitigation Quiz

Earthquake Mitigation is about...

• Responding to earthquakes in the most effective way.

• Designing and implementing plans that reduce damages from earthquakes before they occur.

• Doing everything possible to predict when, where and how strong the next earthquake will be.

• Locating which areas have the most risk for being struck by an earthquake and advising people to move out of that region.

2: Only buildings not built to seismic code were damaged in San Francisco.

3: Fresno suffered massive casualties, very little remained.

4. 4. Sacramento had lots of broken dishes and cracks in soft walls.

5. 5: Bakerfield had lots of old buildings partially collapse.

6. 6. Some in Los Angeles were awoken by the shaking.

An earthquake has struck this region. Each station has already calculated their distance from the epicenter.

S1 is 10 km from the epicenter

S2 is 15 km from the epicenter

S3 is 20 km from the epicenter

Using triangulation, find the epicenter using this information.
