Google announced on October 15 that Android Earthquake Alerts is expanding from 98 countries and regions to more than 200. Panama and Guatemala are among the locations named. The release does not provide an exhaustive region-by-region list.
The system uses a mobile-based earthquake detection network. Google reports sending more than one billion alerts since its launch. That cumulative delivery figure is a company-reported usage measure, not a count of earthquakes or independent evidence of the system's accuracy.
Google describes three alert levels in active regions: Be Aware for estimated light shaking, Be Ready for stronger shaking, and Take Action for moderate to heavy shaking. The level shown is tied to the estimated conditions rather than a single warning style for every event.
The company plans to add more detail to Be Ready alerts in the coming months. Planned information includes a map and radius of detected shaking, an estimated magnitude, suggested action and a way to learn more as information arrives.
That richer Be Ready display is described as coming soon, separate from the coverage expansion announced today. The post does not establish that every Android device in every newly covered location already shows the redesigned alert.
What to watch: confirm that earthquake alerts are active for the relevant location and device. The announcement does not promise that every earthquake will be detected or that every user will receive warning before shaking begins. The reported alert total should not be read as a guaranteed safety outcome.
