Although most of California's quakes are small in magnitude and cause little or no damage, every year the Southern California area alone has about 10,000 earthquakes!

Annually, California typically experiences two or three quakes large enough to cause moderate damage to homes or other structures.

The California Eathquake Authority reports although earlier earthquakes have been documented—such as significant movement on the southern San Andreas fault all the way back to the 1600s—the earliest reported earthquake in California was on July 28, 1769, noted by members of a Spanish expedition to chart a land route from San Diego to Monterey. Members of the expedition led by Gaspar de Portolá were camped along the Santa Ana River when they felt a strong earthquake.
