San Jacinto fault
From the Simple English Wikipedia, the free encyclopedia that anyone can change
The San Jacinto fault zone is a series of dextral strike-slip faults, located in southern California. The San Jacinto fault zone accommodates a portion of the deformation caused by the opposing movements between the North American and Pacific plates. The San Jacinto fault zone branches westward from the San Andreas fault zone in the Transverse Ranges. The fault zone is characterized by a series of strike-slip faults that cross through the pre-Cretaceous metasedimentary and Cretaceous plutonic rocks of the Peninsular Ranges as well as late Cenozoic sedimentary rocks of the Salton Trough (Dibblee, 1954; Sharp, 1967; Matti and Morton, 1993; Morton and Matti, 1993). Throughout the fault zone there are minor compressional, tensional, and oblique zones, but most of the plate motion is taken up by a series of dextral strike-slip faults (Dibblee, 1954; Sharp, 1967; Sanders, 1989).
