SMRTR summary
Google's Android Earthquake Alert system uses smartphones to detect seismic activity and warn users of imminent earthquakes. It analyzes data from multiple devices to identify earthquakes and sends alerts to nearby users. Since 2020, it has issued nearly 1,300 alerts in 98 countries, covering 2.5 billion people. Alerts can provide up to a minute of warning, potentially saving lives. The system has improved over time, with only three false alarms reported.
