Google's earthquake early-warning system has used phone accelerometers on Android devices to increase quake alerts by tenfold across 98 countries.

Google has admitted its earthquake early warning system failed to accurately alert people during Turkey's deadly quake of 2023. Ten million people within 98 miles of the epicentre could have been sent Google's highest level alert - giving up to 35 seconds of warning to find safety.

Google's Android Earthquake Alerts system faced criticism for its inadequate response during the February 2023 Turkey earthquake, which resulted in over 55,000 deaths. The system's miscalculation of the quake's magnitude led to minimal urgent alerts being sent.
