San Francisco, Sacramento and the Sierra Nevada are on the North American Plate. The two plates crisscross with many active and passive convulsion faults.
The communities of Daly City, Point Reyes Station and Bodega Bay lie squarely on the San Andreas. Scientist project the San Andreas Fault line could cause a devastating earthquake in California by 2030. The San Andreas fault caused the biggest earthquakes in California with an approximate magnitude vii.9 in 1857 (Southern California) and 1906 (San Francisco).

History shows that five large earthquakes on the Hayward mistake have occurred on boilerplate every 150 years—last being in 1868. The Hayward fault is due for another big earthquake very soon. The Hayward mistake runs through the East Bay hills from Richmond to San Jose.
Well-nigh 3 million people currently alive forth the fault. Co-ordinate to U.S. Geological Survey (USGS), the Hayward fault is a "tectonic time bomb," set to go off anytime at present.
Hayward Error Earthquake Scenario
This scenario shows the ground shaking for a magnitude 7.0 earthquake on the Hayward error with the epicenter in Oakland, California. In this computer simulation synthetic through a collaborative effort between the United states of america Geological Survey and the Southern California Earthquake Center, the slip or outset beyond the error has the earthquake rupture start in Oakland. These scenarios are larger than the magnitude six.8 Hayward 1868 earthquake, but are about as likely to occur because at that place has not been a large convulsion on the northern portion of the Hayward fault for near 300 years.

Calaveras Fault
The Calaveras error is a major adjunct of the San Andreas fault in Northern California.
UC Berkeley reports that there is potential for larger earthquakes in the San Francisco Bay Area due to the direct connection between the Hayward and Calaveras faults.
