USGS Quaternary Fault and Fold Database

This database contains information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). Maps of these geologic structures are linked to detailed descriptions and references. Used to supplement faults mapped on the USGS 2007 Geologic Map of the State of Hawaii.
