Three types of geological hazards, referred to as seismic hazard zones, may be featured on the map: 1) liquefaction, 2) earthquake-induced landslides, and 3) overlapping liquefaction and earthquake-induced landslides. In addition, a fourth feature may be included representing areas not evaluated for liquefaction or earthquake-induced landslides.

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. The slip rate and maximum magnitude of earthquakes associated with a fault ...

Current Earthquake Information. Fault trace visible as a line of trees above the orange grove east of Hemet, CA along State 74. While most of the major fault lines have some surface expression here, there are many that do not. These faults can also produce large earthquakes, such as the M6.7 Reseda/Northridge Earthquake of January 17, 1994.Brown lines are known hazardous faults and fault zones. Magnitude = ? for new earthquakes until a magnitude is determined (takes 4-5 minutes). Maps are updated within 1-5 minutes of an earthquake or once an hour.
