U.S. Earthquake Faults shows the vast majority of faults in the continental U.S. that the USGS classifies as "Historic" (active in last 150 years) and "Holocene to Latest Pleistocene" (active in last 15,000 years). That includes over 300 faults and 700 fault lines (some faults have multiple fault lines). It does not include all faults or faults classified as "Quaternary" (15,000 to 1,600,000 years).
All fault lines and distances are approximations. For more information, go to the app's web site (http://www.usfaults.com) or the USGS web site (http://www.usgs.gov). Thank you USGS!
