The U.S. Geological Survey reports Southern California experiences about 10,000 earthquakes annually, though most are too small to be felt. Only several hundred each year exceed magnitude 3.0, and roughly 15 to 20 are stronger than magnitude 4.0. Major earthquakes can also generate aftershocks for months afterward.
