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 ...
This section of the San Andreas, located near the tiny central Californian town of Parkfield, last shook back in 2004. ... odds that a big earthquake will hit the fault line within 50 years ...
The plate margin that remains in California is that of the strike-slip San Andreas Fault (SAF), the diffuse Pacific–North American plate boundary that extends east into the Basin and Range Province of eastern California and western Nevada (a seismically active area called Walker Lane) and southwest into the California Continental Borderland ...
Scientists estimate that this section of fault—over the past 1,000 years—usually triggered a sizable earthquake every 180 years (give or take 40). But the southern San Andreas Fault (SSAF ...
The average timespan between earthquakes over the course of the last millennium has been about 180 years. ... including the nearby San Andreas Fault which runs under the small population town of ...
San Andreas Fault comes into being as the North American plate begins splitting the Farallon plate in two. 17 Ma - 14 Ma Miocene: Columbia River Basalt Group forms. 8 Ma Miocene Onset of faulting creating the Basin and Range geologic province. 5 Ma Miocene - Pliocene
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.
