How Android Phones Became an Earthquake Warning System
GLOBAL, JUL 17 – Google's system uses accelerometers in Android devices to issue timely earthquake alerts, reaching 2.5 billion users across 98 countries with over 790 million warnings sent.
- On July 17, 2025, a new study in Science shows that the Android Earthquake Alerts system, using smartphone accelerometers, can detect earthquakes in real time and warn users before shaking occurs.
- To complement seismic networks, Google expanded its Android Earthquake Alerts system in September 2024 to cover all US states, serving as a supplementary solution in underserved regions.
- The study recorded an average of 312 earthquakes per month across 98 countries, according to the study, demonstrating the system’s extensive detection performance.
- In that event, the system issued its first alert eight seconds after the quake began, showing rapid detection and potential early warning benefits.
- Future updates could enhance post-earthquake information delivery to emergency responders, with performance varying by region, phone density, and event size.

How Google's Android earthquake detection system can save lives
If you're in an earthquake-prone area and own an Android phone, it could save your life. It may even have already done so. The Android Earthquake Alert (AEA) system, which began in the U.S. in 2020 and has since expanded globally, sends an automatic alert approximately one minute before the ground starts shaking. That can be enough time to take cover or warn others nearby.
