Faults of Southern California

Southern Region

The area covered by this map, which extends from the Transverse Ranges (the San Gabriel and San Bernadino Mountains) in the north to Baja California, Mexico, in the south is dominated primarily by northwest-trending faults, generally of a right-lateral strike-slip nature, though faults of every type and orientation can be found here. In this area is the Salton Trough, a great inland basin, much of which is below sea level, that harbors the Salton Sea, a dominant feature of the right-hand side of this map. Several offshore fault zones are shown as well.
