Android Earthquake Alerts System provides early warnings globally

The Android Earthquake Alerts System sent warnings to users in Dhaka, Chattogram, and nearby districts before they felt the earthquake on 2 December 2023 at 9:35 am. The system uses smartphone accelerometers to detect tremors and send alerts to Google's earthquake detection server, which then notifies users in affected areas. This system effectively turned over 2 billion Android phones into a global earthquake detection network, providing early warnings to protect lives and property.
