This 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. 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.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The map is used by cities and counties to regulate development and by property owners selling property within areas where seismic hazard zones have been identified. Local governments can withhold development permits until geologic or soils investigations are conducted for specific sites and mitigation measures are incorporated into development plans. Sellers of property use the maps to check the location of their specific site and if applicable, disclose to the buyer that the property lies within a seismic hazard zone.</SPAN></P><P><SPAN>Information about the Alquist-Priolo Earthquake Fault Zoning (AP) Act and links to data downloads is </SPAN><A href="http://www.conservation.ca.gov/CGS/rghm/ap/"><SPAN>here</SPAN></A><SPAN>.</SPAN></P><P><SPAN STYLE="font-weight:bold;">UPDATE HISTORY:</SPAN></P><UL><LI><P><SPAN STYLE="font-weight:bold;">11/6/13 - ADDED to SDE</SPAN></P></LI><LI><P><SPAN STYLE="font-weight:bold;">01/18/18 - Updated with data from Calif.
