Overview
- Google announced on Thursday that the Android Earthquake Alerts System now covers more than 200 countries and regions, up from 98.
- Since the system launched in 2021, Google says it has delivered over one billion earthquake alerts to Android users worldwide.
- The network uses idle phones’ accelerometers to detect the first fast seismic waves, sends quick signals and rough locations to Google, and issues warnings when multiple devices report the same shaking.
- Google plans to update the mid‑tier “Be Ready” notification in the coming months to show a map with a detected‑shaking radius, an estimated magnitude, recommended safety actions, and a button for more details, and its highest‑urgency “Take Action” alert can override phone settings to ensure visibility.
- The wider rollout could extend early warning where local systems are limited and potentially save lives, but effectiveness depends on users having location and Earthquake Alerts turned on, an active data or Wi‑Fi connection, and stationary phones for best detection.
