Features: • Interactive map view • Shows closest faults • Allows zooming in • Displays distances to faults • Quickly displays faults in the Bay Area, southern California and the state The vast majority of California faults the USGS classifies as "Historic" (active in the last 150 years) and "Holocene to Latest Pleistocene" (active in the last 15,000 years) are shown. That includes over 115 faults and 248 fault lines (some faults have multiple fault lines). Faults classified as "Quaternary" (15,000 to 1,600,000 years) by the USGS aren't shown. Tapping a fault will display its name. The locations of recent or historic earthquakes are not shown. Many other apps do that. This app simply shows the approximate locations of faults in California and distances to your current location or a location you specify. It is intended for people that live in California. IOS 16.0 or later and an active WiFi or cellular service (preferably both) is required. It should work on iPhones and iPads released in the last 6 to 7 years.

Great California fault map without having to spend lots of time web-crawling and trying to navigate the convoluted USGS sites. Would like to have more backup data, though, such as type of fault, history of related earthquakes, and brief, non-scientific narrative of relative likelihood for future EQ's. if you can add hazard overlays (e.g. Liquefaction zones, tsunami threat, unstable soils, etc.), I know MANY of us living in the zones will be quick to subscribe and tell our friends and neighbors. This is a good start - keep up the good work! -- Ladylonghorn444, 2012-09-30 ### ****- "Perfect tool for a realtor." Pretty basic information every California resident should know. Wish it covered more than just California. -- AustinDale, 2012-04-05 ### ***** "Informative!" Nicely laid out and clear with a lot of data . My kids love finding the nearest fault line while we are driving around. -- kclf, 2012-03-11 ### ***** "California Earthquakes: great info" App works well. Hope it can be expanded to other areas. Very informative. I use it as I travel. -- JV's iPad, 2012-03-05 ### ***** "Very informative and easy to use!" In California everyone wants to know how far they and their relatives are from an earthquake fault. Will also be helpful when we feel the next quake. -- RTXphone, 2012-02-21 [View all California Earthquake Faults reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## California Earthquake Faults Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | United States | Weather | #17 | | Top Paid | Türkiye | Weather | #215 | ## California Earthquake Faults Available In - [United States](https://apptail.io/app/california-earthquake-faults-fDoz/united-states) - [Kazakhstan](https://apptail.io/app/california-earthquake-faults-fDoz/kazakhstan) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
