Step 2. The number of earthquakes, both low and high magnitude, was nor-malized by the length of the fault line for each major fault in Southern California. From this, a list was made for both high and low magni-tude events. The top 20 most-active fault lines was determined by. combining the two lists.

The eroded cliffs of "fault gouge" are the prominent feature at this location.California's Earthquake History. 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 ...The San Andreas fault is one of the most famous and—because of its proximity to large population centers in California—one of the most dangerous earthquake-generating faults on Earth. Concern about the timing, magnitude, and location of future earthquakes, combined with convenient access, have motivated more research on this fault than on any other. In recent years, an increasing number of ...The Elsinore fault zone is one of the largest in southern California, and in historical times, has been one of the quietest.
