Fault Line watches AFAD, Kandilli, USGS and EMSC around the clock and pushes verified earthquake alerts to your phone the moment they are published.
Fast alerts are only the beginning. Fault Line keeps you informed and your family connected before, during and after an earthquake.
Fault Line ingests data directly from AFAD, Kandilli (KOERI), USGS and EMSC, then cross-checks and deduplicates events so you get a single verified alert instead of noise.
Create a private safety circle with the people you care about. When an earthquake hits, a single glance tells you everyone's status.
Numbers tell you magnitude. People tell you what it was actually like. Felt reports and moderated comments from users near the epicenter arrive in real time.
Recent seismic activity on an interactive map with magnitude, depth and distance from you.

Typically within seconds of an event being published by the seismic network. Delivery time can vary with network conditions and the reporting agency's own latency.
No, and neither does anyone else. Earthquake prediction is not scientifically possible today. Fault Line reports confirmed events from official sources as fast as possible.
No. Alerts are delivered via push notifications, so the app doesn't need to run in the background or poll for data.
