Quaternary Fault and Fold Database of the United States
NOTE: Fault data were last updated 3 November 2010.
You can download data by any of these methods, either download complete data from the ftp site or download a subset of the data from the Interactive Map Server (IMS). Data is in ArcGIS shapefile format.
It is recommended to use Internet Explorer 7 or greater. Mozilla, Safari do not work well. Firefox is okay.
Using the IMS, you can zoom to an area of interest and extract faults and fault areas on the map (zip and ship). Data are in geographic coordinates (lat/lon), in shapefile format, and zipped for download.
