View of the San Andreas Fault, one of the few transform faults exposed on land. Photo credit The San Andreas Fault is the boundary where two tectonic plates - the Pacific Plate and the North American Plate, meet. The fault runs across the state of California from Mendocino to the Mexican border, splitting it into two parts. San Diego, Los Angeles and Big Sur lies on the Pacific Plate, while San Francisco, Sacramento and the Sierra Nevada are on the North American Plate.
