A map displaying each of the seven major faults in the San Francisco Bay Area, and the probability of an M6.7 earthquake or higher occurring on each fault between 2003 and 2032 The slip on the San Andreas Fault which caused the 1906 San Francisco earthquake was visible in Wrights Tunnel along the South Pacific Coast Railroad after the earthquake
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 most famous fault in the U.S. is San Andreas. ... The area also contains another seismic quirk—the fault in this area usually records an earthquake of around magnitude 6 every 22 years ...
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.
Studies of past earthquake traces on both the northern San Andreas Fault and the southern Cascadia subduction zone indicate a correlation in time which may be evidence that quakes on the Cascadia subduction zone may have triggered most of the major quakes on the northern San Andreas during at least the past 3,000 years or so. The evidence also ...
The bay is formed along a submerged portion of the San Andreas Fault. The fault divides the Point Reyes Peninsula through Tomales Bay in the north, and the Bolinas Lagoon in the south. The Bear Valley Visitor Center in Point Reyes Station is home to the Earthquake Trail, where visitors can see a visible rift formed on the fault during the 1906 ...
The Hayward Fault is parallel to the San Andreas Fault, which lies offshore and through the San Francisco Peninsula. To the east of the Hayward Fault lies the Calaveras Fault. In 2007, the Hayward Fault was discovered to have merged with the Calaveras Fault east of San Jose at a depth of 6.4 kilometers (4.0 mi), with the potential of creating ...
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
