California Earthquake Faults

California Earthquake Faults helps you quickly locate earthquake faults based on your current location or a location you specify.

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. You’ll find more details at https:www.calfaults.com. Feel free to contact us at [email protected].
