An Earthquake has struck California!
Draw in a Mercalli Intensity map using the following information.
1: San Jose had many buildings collapse, including some built to seismic code.
2: Only buildings not built to seismic code were damaged in San Francisco.
3: Fresno suffered massive casualties, very little remained.
4. Sacramento had lots of broken dishes and cracks in soft walls.
5: Bakerfield had lots of old buildings partially collapse.
6. Some in Los Angeles were awoken by the shaking.
7. People in San Diego wondered if there was a large truck was passing, cars slightly shook.
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.
Name three different earthquake mitigation strategies and explain their pros and cons.
1. Find the P and S wave arrival times for these three stations using the image given.
2. Find the difference between the arrival times.
3. Which stations was closest to the earthquake? Which one was the farthest?
