In addition, a fourth feature may be included representing areas not evaluated for liquefaction or earthquake-induced landslides.The California Geological Survey, a division within the California Department of Conservation, provides data and analysis of California's seismic and geologic hazards. These hazards include earth shaking (strong motion), fault ruptures, landslides, liquefaction, and tsunamis as well as mineral hazards such as radon, mercury, and asbestos.The individual fault data sheets include information on map and data sources, fault location, geologic setting of the fault, the geomorphic expression of the fault, recency of fault movement, fault slip rate(s), and fault zone length and orientation.

A Southern California Earthquake Data Center map of fault lines in the Los Angeles region shows two faults - one with two branches - that run through or near the South Bay. The San Andreas Fault is probably the most famous of fault lines. It is the fault that people in California refer to as THE Fault. Through Southern California, it stays a fair distance from major population centers until the Cajon Pass, where it passes right next to San Bernardino, Redlands, and Palm Springs. In California, the known active surface faults are classified in the 1997 Uniform Building Code as A faults, B faults and C faults. An A fault is the most destructive and a C fault is the least destructive. Only the A and B faults are included in the probabilistic maps.
