The earthquake occurred along the Calaveras Fault, with the epicenter 16 kilometers (9.9 mi) northeast of San Jose, and at a depth of 8 km (5.0 mi). The shock was felt in Sacramento in California's central valley.
The earthquake was reported to be felt over an area of 120,000 square kilometers (46,000 sq mi). Morgan Hill was the worst affected, with a number of mobile homes sliding off foundations, and moderate damage to several masonry buildings in the city. The communities of San Jose, San Martin and Coyote were some areas that experienced minor damage. In Santa Clara County, over 550 buildings were reported to have received at least minor damage.
The outline of aftershocks show that the rupture propagated southeast over a 25 km (16 mi) section of the fault, as far as San Martin, to the location of the 1979 Coyote Lake earthquake's mainshock. That event's aftershock zone also stretched to the southeast.
