These data are a geospatial representation of liquefaction potential for the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data are the product of an analysis that created a detailed liquefaction probability map covering the northern Santa Clara County and western Alameda County areas. The approach of Holzer, Noce, and Bennett (U.S. Geological Survey) was used to produce the data; Holzer, Noce, and Bennett used the liquefaction potential index parameter as an indicator for liquefaction hazard in their mapping of a smaller part of northern Santa Clara County and western Alameda County. These raster .IMG data were developed and are intended for use in GIS applications such as ESRI's ArcGIS software suite.
