Earthquake Hazards in Southern California
Southern Californians are well acquainted with the hazards created by earthquakes because the region is traversed by many fault zones capable of producing seismic events. Earthquake-generated hazards include:
A useful summary of the kinds of earthquake hazards facing southern Californians can be found in Putting Down Roots in Southern California.
Earthquake-hazard Studies by the U.S. Geological Survey (USGS)
The USGS Earthquake Hazards Program conducts research and mapping studies in southern California that answer questions about:
The hazards program also conducts post-earthquake investigations that map ground-rupture patterns, evaluate ground-response patterns, and determine regional stress distribution throughout southern California prior to and after a major earthquake event. Extensive post-earthquake investigations have been conducted for the 1968 Borrego Mountain earthquake, the 1971 San Fernando earthquake, the 1979 Imperial Valley earthquake, the 1992 Landers earthquake, the 1994 Northridge earthquake, and the 1999 Hector Mine earthquake.
The USGS also maintains a National Earthquake Information Center
Southern California Earthquake Data Center
The SCEC Data-Center website has many useful links that describe earthquake activity and earthquake geology in southern California. Among these are:
