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.
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 ...
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 ...
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 ...
The San Andreas Fault is an active continental transform fault, and there is evidence for recent basaltic volcanism across this region. Majority of magmatism here occurs as a result of releasing fault bends along the transform which form pull-apart extensional basin structures: Coachella Valley, Imperial Valley, Owens Valley, Panamint Valley ...
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 ...
The biggest quake came around 9 a.m., measured a 4.6, and happened under the Salton Sea, which sits on the San Andreas Fault line. Small earthquakes could agitate San Andreas Fault, says seismologists
The San Andreas fault runs through this town, and six successive magnitude 6 earthquakes occurred on the fault at unusually regular intervals, between 12 and 32 years apart (with an average of every 22 years), between 1857 and 1966. [1] The latest major earthquake in the region struck on September 28, 2004.
