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.

The California Geological Survey produces State-mandated regulatory maps that show “Zones of Required Investigation” for liquefaction (and landslide) hazard. Google Earth software enables you to zoom in beyond the level of accuracy provided in these data layers.
