The red line on this map of southern California is the San Andreas fault. Other lines represent other active faults some of which lie beneath urban centers. The San Andreas fault passes through the cities of San Bernardino, Lancaster, Palmdale, and only 3 miles from San Francisco. Los Angeles also has active faults.

Deformation observed along the San Mateo (SMT) and San Onofre trends (SOT) in southern California has been explained by two opposing structural models, which have very different hazard implications for the coastal region. One model predicts that the deformation is transpressional in a predominantly right lateral fault system with left lateral step-overs. Conversely in the alternative model ...

The Working Group on California Earthquake Probabilities (WGCEP, 1995, 2007) identified a continuous belt of deformation south of the San Andreas fault between Los Angeles and Ventura that has the potential to produce more than four damaging earthquakes in the next century ().Extremely high rates of contractional deformation …Geologic rates.
