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,

Back in 2020, Google kicked off a project to crowdsource signals from Android phones that an earthquake might be imminent. The system leveraged the accelerometers inside these devices to gather seismic data, combine it to detect patterns consistent with an earthquake, and deliver timely alerts to people who might be affected.

An early-warning system on Android phones has detected more than 1,000 earthquakes worldwide since 2021, sometimes giving people 15 to 60 seconds’ notice

Google's Android Earthquake Alerts system uses your phone's accelerometer to provide crucial seconds of warning before seismic activity.

Google’s Android Earthquake Alerts program is a globe-spanning earthquake early-warning system that uses billions of phone sensors to detect seismic shaking and alert those at risk
