2022年9月27日 · The Quaternary Fault and Fold Database of the United States database contains information on faults and associated folds in the United States that demonstrate geological evidence of coseismic surface deformation in large earthquakes during the past 1.6 million years (Myr).

In general, the Calaveras fault zone is expressed as numerous strands that form a zone tens of meters to more than 500 m in width (1982 #5521). Locally the Paicines fault is expressed as a zone as much as 2 km wide.

Calaveras fault: a northern segment from Calaveras Reservoir north to the San Ramon area, and a southern segment from Calaveras Reservoir to south of Hollister.

The map shows the locations of all known or suspected fault traces formed by recent tectonic displacements of the ground surface along the Hayward and the southern part of the Calaveras fault zones. The displacements may have been due to violent rupture during earthquakes, to imperceptible movement not accompanied by felt earthquakes (slippage ...

As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. For the most up-to-date information, please refer to the interactive fault map. Archived report (descriptions no longer maintained) Calaveras fault zone, Southern Calaveras section (Class A) No. 54c

presents a modern review of the Calaveras fault zone, and Bakun (1980) summarizes the seismic activity on its southern reach for a 10-yr period beginning in 1969. In the epicentral area of the Coyote Lake earthquake (Figure 2), the Calaveras fault …

The 142-km-long Calaveras Fault zone is an active right-lateral transform fault that accommodates 24- to 35-percent of the relative motion between the Pacific and North America plates at the latitude of the southern San Francisco Bay area (Figure 1).
