Orogeny. Gorda-California-Nevada. 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 Californias. [1] It forms the tectonic boundary between the Pacific Plate and the North American Plate. The individual fault data sheets include information on map and data sources, fault location, geologic setting of the fault, the geomorphic expression of the fault, recency of fault movement, fault slip rate(s), and fault zone length and orientation. Faults are grouped into slip rate categories of <0.02 mm/yr, < 0.2 mm/yr, and <1 mm/yr.It runs almost the length of California, parallel to the Pacific coast, making it one of the longest fault lines in the world. Movement along the fault line has led to major earthquakes, including the 1906 San Francisco earthquake, which killed an estimated 3000 people and left half the city’s residents homeless.Acquisition of additional information and data sets in the future may however require revisions of these maps.
