Description: Earthquake Paleoliquefaction Sites, 1996 (1:24,000) - Shows paleoliquefaction features that were caused by strong-motion earthquakes having energies equivalent to Mb 5.0 or greater. This layer shows locations of sites where paleoliquefaction features have been identified by geologists. Ages of the features were determined by radiocarbon dating, dating of associated archaeological artifacts, and floodplain stratigraphy. Data were derived from a database that appears as an appendix in a project report for the National Earthquake Hazards Reduction Program (U.S. Geological Survey), Grant No. 14-08-0001-G2117.
