The Calaveras Fault is a major branch of the San Andreas Fault located in northern California in the San Francisco Bay Area. To the east of the Hayward-Rodgers Creek fault, the Calaveras fault extends 123 km, splaying from the San Andreas fault near Hollister and terminating at Danville at its northern end. It runs east of the San Andreas, diverging from it in the vicinity of Hollister, California, and is responsible for the formation of the Calaveras Valley there. Between the San Andreas Fault and the Calaveras Fault lies the Hayward Fault, which diverges from the Calaveras Fault east of San Jose, California. To the east lies the Clayton-Marsh Creek-Greenville Fault. These four fault structures are the some of the major faults in California at the latitude of San Francisco. All are right lateral moving strike-slip faults.
The Calaveras Fault was named for Calaveras Creek in Santa Clara County east of San Jose where it was first identified. ("Calaveras" is Spanish for "skulls".) "Calaveras" is also the name of a California county in the foothills of the Sierra Nevada mountains, some 100 miles (160 km) east of Santa Clara County, far from the Calaveras Fault.

Famous quotes containing the word fault:
“Dug from the tomb of taste-refining time,
Each form is exquisite, each block sublime.
Or good, or bad,disfigurd, or depravd,
All art, is at its resurrection savd;
All crownd with glory in the critics heavn,
Each merit magnified, each fault forgiven.”
—Martin Archer, Sir Shee (17691850)
