Southern California faults

The faults of southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. (Click on icon for a larger image.) Highlighted in purple are the San Andreas fault (left) and Santa Monica Bay complex (right). Foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse Range. Faults in the upper left are part of the Eastern California Shear Zone, connecting northward with the Walker Lane region. Faults extend deeper than shown.

Cumulative energy released by all earthquakes in Southern California from 1932 through July 2014. Highest energy in red, lowest energy in dark blue. Data from the Southern California Earthquake Center. (Click on icon for a larger image.)

Most of central and northern California rests on a crustal block (terrane) that is being torn from the North American continent by the passing Pacific plate of oceanic crust. Southern California lies at the southern end of this block, where the Southern California faults create a complex and even chaotic landscape of seismic activity.

Seismic, geologic, and other data has been integrated by the Southern California Earthquake Center to produce the Community Fault Model (CFM) database that documents over 140 faults in southern California considered capable of producing moderate to large earthquakes.^[1] A three-dimensional (3D) model has been derived that can be viewed with suitable visualization software (see image).^[2] The probability of a serious earthquake on various faults has been estimated in the 2008 Uniform California Earthquake Rupture Forecast. Details on specific faults can be found in the USGS Quaternary Fault and Fold Database.
