Deprem app
Earthquakes, in your pocket.
An earthquake app that alerts you by the shaking expected where you are, not by magnitude alone. AFAD, Kandilli, EMSC and USGS in one place; no account needed.
- iPhoneComing soon to the App Store
- AndroidComing later
Until the app is out, you can get the same intensity alerts in this browser.
What it does
Live map
Earthquakes merged from four sources on the map within seconds. Clusters, filters and a source comparison.
Personal intensity alerts
You are notified when the expected shaking at your saved places crosses your threshold; a large quake far away does not wake you for nothing.
Live Activities and Dynamic Island
After a significant earthquake, magnitude, aftershocks and felt reports update on the Lock Screen and in the Dynamic Island.
Widgets
Latest earthquakes, a daily summary and the nearest assembly area on the Home Screen and Lock Screen.
Apple Watch
The latest earthquakes and their details on Apple Watch.
Station mode
Turn a charging iPhone into an earthquake sensor. It listens for shaking 50 times a second and sends only a short summary. Community detection is experimental and runs in shadow mode.
Aftershock forecast
Aftershock probabilities for the next day, week and month after earthquakes of M4 and above (Reasenberg–Jones).
Active faults
The GEM Global Active Faults map and the nearest fault to every earthquake.
I’m safe
Tell your family with one tap; report shaking you felt even before the earthquake is announced.
Offline assembly areas
Assembly areas near you are saved on the phone and open even without a connection.

Privacy first
No account, no ads, no trackers. Your places are rounded to about 100 m, felt reports are kept on cells of about 0.7 km², and station mode sends only an area of about 5 km².
Deprem is not an official warning system; AFAD is the official authority.
