Google is enhancing its Android earthquake alerts system, expanding its reach to over 200 regions worldwide, up from 98. The system, which has been operational since 2021, uses sensors in Android smartphones to detect initial tremors and has sent over a billion alerts. New locations added include Panama and Guatemala. The “Be Ready” alert will now provide more detailed information, including the earthquake's epicenter, estimated magnitude, a map of detected shaking, safety steps, and a button for further information. The alert system includes three types: "Be Aware" for light shaking, "Be Ready" for stronger shaking, and "Take Action" for moderate to heavy shaking.
