U.S. Earthquake Faults shows your current location (or a location you specify) the closest faults in the continental United States and approximate distances to those faults. There are 5 screens: 1. Fault Maps: A map view of the current (or found) location and the names and distances to the closest 4 faults. And a map view of the faults in the continental United States. You can zoom into the 4 closest faults. 2. Distances: Names, distances and color coding of the closest faults 3. Find: Find the nearest faults to a location you specify 4. App Info 5. App Settings 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 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!

No faults in Alaska. Only the major faults have been digitized. Zooming in does not reveal more. Pretty disappointing. Having read the developer’s response, I agree. But then the app needs a new name. Still disappointed. **Developer response:** This review is not fair or accurate. 1. The app description has always made it clear that the app covers the continental United States. The continental United States does not include Alaska and Hawaii. 2. The app has always covered the continental United States, not just the western states. 3. The app description has always made it clear that the app shows the vast majority of faults the USGS classifies as “Historic” (active in the last 150 years) and “Holocene to Latest Pleistocene” (150 to 15,000 years) and that it does not show faults classified as “Quaternary” (15,000 to 1,600,000 years). The app description has always been accurate. It appears that the reviewer did not read the description before purchasing the app. ## Frequently asked questions about U.S. Earthquake Faults ### What is U.S. Earthquake Faults?
