Understanding Tectonic Hazards

A student reads an article about the 1906 San Francisco earthquake.The student lists several problems that may occur if a region is hit by a massive earthquake.

1. production of acid rain
2. damage of properties and lives
3. contamination of air
4. loss of electrical infrastructure
5. creation of tsunamis and landslides
