Earthquake California
Earthquakes in California are common since the state is located on the San Andreas Fault, which cuts across California and forms the tectonic boundary between the Pacific and the North American Plate. There are many thousands of small earthquakes per year, most of them so small that they are not felt.
The largest recorded earthquake in California was the 1857 Fort Tejon earthquake, with an estimated magnitude of 7.9. The most destructive earthquake to date was the 7.8 magnitude 1906 San Francisco earthquake, when more than 3000 people perished in the earthquake and the fires that followed.
More recently, the 1989 Loma Prieta earthquake, which registered 6.9 and affected the San Francisco bay area, and the 1994 Northridge earthquake which registered 6.7 and hit the Greater Los Angeles area, caused widespread damage and deaths in their respective regions.
