The Cascadia subduction zone intersects the San Andreas fault at the Mendocino triple junction. It has been hypothesized that a major earthquake along the Cascadia subduction zone could trigger a rupture along the San Andreas Fault. [2] [3] [4] In the south, the fault terminates near Bombay Beach, California, in the Salton Sea.
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 Cascadia subduction zone is capable of producing megathrust earthquakes on the order of MW 9.0. Due to the relative plate motions, the triple junction has been migrating northwards for the past 25–30 million years, and assuming rigid plates, the geometry requires that a void, called slab window , develop southeast of the MTJ.

This section of the San Andreas, located near the tiny central Californian town of Parkfield, last shook back in 2004. ... (USGS), the stretch of fault near Parkfield is a “transition zone ...
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 ...
The Mendocino fracture zone is a fracture zone and transform boundary over 4000 km (2500 miles) long, [1] starting off the coast of Cape Mendocino in far northern California. It runs westward from a triple junction with the San Andreas Fault and the Cascadia subduction zone for about 300 km to the southern end of the Gorda Ridge. It continues ...
The San Jacinto Fault Zone and the San Andreas Fault (SAF) accommodate up to 80% of the slip rate between the North American and Pacific plates.The extreme southern portion of the SAF has experienced two moderate events in historical times, while the SJFZ is one of California's most active fault zones and has repeatedly produced both moderate and large events.
