CGS products have included geologic maps and reports for land-use planning, landslide hazard identification maps, watershed maps, and earthquake-triggered landslide-zone ...

1) It directs the state's California Geological Survey agency (then known as the California Division of Mines and Geology) to compile detailed maps of the surface traces of known active faults. These maps include both the best known location where faults cut the surface and a buffer zone around the known trace(s);
