The 1994 Fault Activity Map of California and Adjacent Areas by Charles W. Jennings (available from the California Geological Survey) was used as a guide. These maps should not be considered as zoning guides, nor be used for risk assessment. Because of the sheer number of faults in southern California, this is not an exhaustive collection.

There are hundreds of identified faults in California; about 200 are considered potentially hazardous based on their slip rates in recent geological time (the last 10,000 years). More than 70 percent of the state's population resides within 30 miles of a fault where high ground shaking could occur in the next 50 years.1. Deadliest dam failure.
