Gulf Of California Rift Zone
The Gulf of California Rift Zone (GCRZ) is the northernmost extension of the East Pacific Rise which extends some from the mouth of the Gulf of California to the southern terminus of the San Andreas Fault at the Salton Sink. The GCRZ is an incipient rift zone akin to the Red Sea Rift. In the GCRZ continental crust originally associated with the North American Plate has been pulled apart by tectonic forces and is being replaced by newly formed oceanic crust and seafloor spreading. The rifting has resulted in the transfer of the Baja California Peninsula to the Pacific Plate.

East Pacific Rise
The East Pacific Rise is a mid-ocean rise (termed an oceanic rise and not a mid-ocean ridge due to its higher rate of spreading that results in less elevation increase and more regular terrain), a divergent tectonic plate boundary located along the floor of the Pacific Ocean. It separates the Pacific Plate to the west from (north to south) the North American Plate, the Rivera Plate, the Cocos Plate, the Nazca Plate, and the Antarctic Plate. It runs south from the Gulf of California in the Salton Sea basin in Southern California to a point near 55° S, 130° W, where it joins the Pacific-Antarctic Ridge trending west-southwest towards Antarctica, near New Zealand (though in some uses the PAR is regarded as the southern section of the EPR). Much of the rise lies about 3200 km (2000 mi) off the South American coast and rises about 1,800–2,700 m (6,000–9,000 ft) above the surrounding seafloor.

Guaymas Fault
The Guaymas Fault, named for the city of Guaymas, Sonora, Mexico, is a major right lateral-moving transform fault which runs along the seabed of the Gulf of California. It is an integral part of the Gulf of California Rift Zone, the northern extremity of the East Pacific Rise. The Guaymas Fault runs from the San Pedro Martir Basin located at the southern end of the San Lorenzo Fault (the next transform to the north), and extends southward to the Guaymas Basin, a heavily sedimented rift which includes both continental and oceanic crust and contains numerous hydrothermal vents. The Guaymas Fault is often grouped together with the three transform faults to its north as the Guaymas Transform Fault System. These faults are, from north to south, the Ballenas, Partida, San Lorenzo, and Guaymas. This system of fault extends some 325 km, linking the Delfin Basin The Delfin Basin (''delfín'' is Spanish for "dolphin") is a pair of interconnected submarine depressions located on ...

Delfin Basin
The Delfin Basin (''delfín'' is Spanish for "dolphin") is a pair of interconnected submarine depressions located on the seabed of the northern Gulf of California. The northernmost of these is called the Upper Delfin Basin while the southernmost is called the Lower Delfin Basin. Both of these features are areas of subsidence caused by extensional forces imparted by a spreading center associated with the East Pacific Rise. The two basins are linked by a short transform fault which was the apparent source of an earthquake of magnitude 5.5 on November 26, 1997. The Delfin Basin is linked to the Guaymas Basin The Guaymas Basin is a marginal rift basin, the largest such basin in the Gulf of California. It consists of two axial troughs (northern and southern). The basin results from the activity of one of the several spreading centers in the Gulf. The ... located about 325 km to the south by a series of four transform faults called the Guaymas Transform Fault System. It is a ...

Consag Basin
The Consag Basin is a submarine depression in the far northern part of the Gulf of California associated with the East Pacific Rise. It lies south of the Wagner Basin with which it is closely linked. The depression is a result of subsidence caused by the extensional forces probably imparted by the same spreading center which has produced the Wagner Basin. Both basins are bounded on their eastern side by the Wagner Fault, a primarily normal (vertical motion) fault which dips approximately 60 degrees to the northwest. The western side of the basin is bounded by another normal fault, the Consag Fault which dips in a direction opposite the Wagner Fault. The seabed between these faults is sinking. The Consag Basin is linked to the Delfin Basin located to its south by a poorly understood deformation zone which further research may eventually define as a transform fault A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly hor ...

Wagner Basin
Wagner Basin is a submarine depression in the far northern part of the Gulf of California. The basin is currently tectonically active. It is the northernmost underwater depression associated with the East Pacific Rise and is located near the southern end of the Cerro Prieto fault. The depression is a result of subsidence caused by the extensional forces imparted by a spreading center. The Wagner Basin is bounded on its eastern side by the Wagner Fault, a primarily normal (vertical motion) fault which dips approximately 60 degrees to the northwest. The western side of the basin is bounded by another normal fault, the Consag Fault which dips in a direction opposite the Wagner Fault. The seabed between these faults is sinking. The basin is linked to the dextral (right lateral-moving) Cerro Prieto Fault at its north end.

Cerro Prieto
Cerro Prieto ( coc, Wee Ñaay, eng, "Black Hill") is a volcano located approximately 29 km (18 mi) SSE of Mexicali in the Mexican state of Baja California. The volcano lies astride a spreading center associated with the East Pacific Rise. This spreading center is also responsible for a large Geothermal power, geothermal field, which has been harnessed to generate electric power by the Cerro Prieto Geothermal Power Station. The Cerro Prieto spreading center intersects the southern end of the Imperial Fault and the northern end of the Cerro Prieto Fault.Fuis, Gary S. and Walter D.

Brawley Seismic Zone
The Brawley Seismic Zone (BSZ), also known as the Brawley fault zone, is a predominantly extensional tectonic zone that connects the southern terminus of the San Andreas Fault with the Imperial Fault in Southern California. The BSZ is named for the nearby town of Brawley in Imperial County, California, and the seismicity there is characterized by earthquake swarms. Geology The Brawley Seismic Zone represents the northernmost extension of the spreading center axis associated with the East Pacific Rise which runs up the axis of the Gulf of California and is in the process of rifting the Baja California Peninsula away from the mainland of Mexico, with significant subsidence taking place at southern California's Salton Sea and at Laguna Salada in Baja California. Other major locations along the axis include the Cerro Prieto spreading center located south of Mexicali, and Wagner Basin (a submarine depression in the Gulf of California).
