The last big earthquake in this area on the San Andreas caused one part of the fault to move past the other by 12 to 14 feet, making it a likely magnitude 7.3 or 7.4 earthquake.
A report from 2008 – co-authored by Jones – estimated that even a magnitude 7.8 quake on the San Andreas Fault would cause fewer fatalities and less economic damage.
A simulation of a plausible major southern San Andreas fault earthquake — a magnitude 7.8 that begins near the Mexican border along the fault plane and unzips all the way to L.A. County's ...
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 U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific plate and the North American plate. Traditionally ...
Simplified fault map of southern California The faults of Southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse ...
About half of the San Andreas Fault system's movement has been from the San Felipe fault zone. [4] It has seen 5.8±2.8 km of right separation since its inception. [3] Both the San Jacinto Fault zone and San Felipe fault zones reorganized in the middle to late Pleistocene era and accumulated 600 meters of sediment during uplift and folding. [4]
Scientists believe they may have found a reason why the San Andreas Fault, the largest seismic hazard in California, has been dormant for more than three centuries.. The average timespan between ...
The Gulf of California Rift Zone (GCRZ) is the northernmost extension of the East Pacific Rise which extends some 1,300 km (800 mi) 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.
