This page has an embedded map showing liquefaction zones in and around the City of Buena Park. The California Geological Survey (CGS) created the data contained in the map below. More information on liquefaction zones, and earthquakes in general, can be found on the CGS Home Page. You can also review the CGS publication "Guidelines for Evaluating and Mitigating Seismic Hazards in California."
Seismic Hazard Zones are organized by "quadrangles." Clicking on the liquefaction zone quadrangles in the map below will give you more information on the specific quadrangle. This includes links to the official published CGS map of each quadrangle, as well as the current CGS "Seismic Hazard Zone Report" for that quadrangle.
