CGS Seismic Hazards Program: Landslide Zones (DOC Hosted)

Note: The DOC hosted version will be maintained through 2022, but is being retired in favor of an ArcGIS Online Hosted version of the same data. Those data can be found at: https://cadoc.maps.arcgis.com/home/item.html?id=921a7c243d074fa081af2b9d19be0315This is a digital Seismic Hazard Zone Map presenting areas where liquefaction and landslides may occur during a strong earthquake. 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. Developers of properties falling within any of the three zones may be required to investigate the potential hazard and mitigate its threat during the local permitting process.
