Global Earthquake Early Warning System Leveraging Android Smartphones

A new study demonstrates the effectiveness of a global earthquake early warning system built using the accelerometers in millions of Android smartphones worldwide. The system, called Android Earthquake Alerts (AEA), rivals traditional seismic networks in accuracy, detecting earthquakes globally and delivering timely alerts to users. Even in regions lacking traditional infrastructure, AEA provides crucial early warning to millions, potentially mitigating earthquake damage. By exploiting the speed difference between seismic waves, AEA issues alerts before the destructive waves arrive, buying precious seconds for people to react.
