Fault Activity Map of California

The 2010 edition of the Fault Activity Map of California was prepared in recognition of the 150th anniversary of the California Geological Survey (CGS). It replaces the Fault Activity Map of California and Adjacent Areas and is more complete with the addition of recent data. The map shows the locations of known faults and indicates the latest age when displacements took place, according to available data. Fault names are indicated on the map where space permits, including newly named faults. The ages of faults on the 1994 map have been revised where improved dating methods were available, and occurrences of surface faulting caused by earthquakes since 1994 have been added.
