Southern California faults
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. A three-dimensional (3D) model has been derived that can be viewed with suitable visualization software (see image). 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.
