The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. According to the United States Geological Survey, Southern California experiences nearly 10,000 earthquakes every year. [3] Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
The San Diego Trough Fault Zone is a group of connected right-lateral strike-slip faults that run parallel to the coast of Southern California, United States, for 150–166 km (93–103 mi). The fault zone takes up 25% of the slip within the Inner Continental Borderlands. Portions of the fault get within 30 km (19 mi) of populated cities ...

The Rose Canyon Fault Zone can produce large earthquakes which can be very destructive due to its proximity to major population centers in Southern California. [8] On the fault, earthquakes nearing magnitude 7 have a recurrence interval between 700±400 [24] and 2,000 years. [23]
