Data Source History: The earthquake planning scenario map was based on a 1:100,000 USGS quad. The map was produced by the California Department of Conservation in 1987, and was part of a study to find the varying degrees of land movement during an earthquake, depending on soil type. Kyle Draganov, Earthwise Consulting, digitized the liquifaction zones from an earthquake planning scenario map produced by California Department of resources. Land in the liquifaction zones are known to be landfill and will liquify during an earthquake.
