California Fault Classification

State of California
  • Added 13 Sep 2018

This layer is a component of 2010 Fault Activity Map of California.

The 2010 Fault Activity Map of California presents a much more detailed depiction of faults in California than previous versions. Faults active in the Quaternary (2.6 Ma) were digitized from their original sources in order to preserve as much of the original detail as possible. Similar to the 1994 Fault Activity Map, the new map is accompanied by an extensive listing of the sources of fault maps and age determinations. In the 2010 Fault Activity Map, the faults are depicted in as much detail as possible at the scale of the map.
