Plaque showing location of San Andreas Fault in San Mateo County. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific plate and the North American plate. Traditionally ...
Simplified fault map of southern California The faults of Southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse ...

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 western and central segments of the Transverse Ranges are bounded to the north and east by the San Andreas Fault, which separates those segments from the Mojave Desert. [1] [2] The eastern segment bounds the southern Mojave Desert. Notable passes along the San Andreas fault include Tejon Pass, Cajon Pass, and San Gorgonio Pass.
The Elsinore Fault Zone is a large right-lateral strike-slip geological fault structure in Southern California. The fault is part of the trilateral split of the San Andreas Fault system and is one of the largest, though quietest faults in Southern California. [1] [2]
The San Felipe Fault Zone (also known as the Agua Caliente or Murrieta Hot Springs Fault zone) is an active Quaternary fault zone made up of continuous right-lateral fault strands]. [1] It is a part of the San Andreas Fault system and it is located in the western Salton Trough spanning three counties: Imperial , Riverside , and San Diego county ...
In the Soledad Basin and the San Andreas Fault Zone, the formation is described by the United States Geological Survey (USGS) as: Early Miocene to Oligocene? yellowish and reddish sandstone, conglomerate, and interbedded andesite-basalt, lying on pre-Tertiary crystalline basement rocks and unconformably below strata of Tick Canyon Formation ...
