A phone-based seismometer network
Sensor Network
Android phones running UdesQuake team up to listen to Türkiye for earthquakes. Each phone listens with its accelerometer while it is charging and lying still.
Join with your phoneWhere the phones are
Provinces with phones in the last 24 hours. Green: sending signals right now.
Individual phones are never shown: phones are grouped at the province centre and no device identity is shared.
Can the network send warnings?
Not yet
To confirm an earthquake, at least three phones in the same area must detect shaking at the same time. The network is experimental and does not issue public warnings. For official alerts, follow AFAD.
How it works
- 1The phone listens while charging and lying still.In a hand, a pocket or on the move it stops listening, so it never drains the battery.
- 2It reports suspicious shaking to the network.Only the measurements are sent (acceleration, frequency, duration) with a location rounded to a 10 km square. No audio and no personal data.
- 3If several phones nearby detect it together, the network confirms it.A single phone trigger is usually a door, a footstep or a passing car. The network only looks at shared events.

Open this page on your phone, put it on a table and tap the table gently. Nothing is sent anywhere.
FAQ
Does it drain my battery?
No. The phone only listens while plugged in; it stops as soon as you unplug it.
What data leaves my phone?
Only shaking measurements (acceleration, dominant frequency, duration), whether the phone was still, and a location rounded to a 10 km square. No audio, camera, contacts or exact location.
Is it available on iPhone?
Not yet; the app is Android only for now. There is no date for an iPhone version.
Can I turn the sensor off?
Yes. In the app, open Settings and switch off "Sismik sensör" (seismic sensor). The rest of the app keeps working.
