- Option in testing to share seismic alerts via networks and messaging to non-Android contacts.
- The feature appears in Google Play Services code 25.40.30 and would use the hashtag #AndroidEarthquakeAlerts.
- The Android alert system detects earthquakes using mobile accelerometers and estimates magnitude and epicenter.
- Notifications show magnitude (≥4,5), distance from the epicenter, and advisories; active service in Spain.
Google is finalizing an option to forward earthquake alerts via social networks and messaging apps, so that the warning also reaches family and friends who do not use an Android phone.
The new feature was discovered in the code of Google Play Services (v25.40.30) and, according to the text found, would allow users to share the notification with a predefined message that includes the hashtag #AndroidEarthquakeAlerts . It is not yet publicly available.
What changes with the sharing option
With this addition, a user could manually notify people without Android (for example, iPhone users or those who do not have the system active) when they receive an earthquake alert near their location.
The system would integrate with social networks and messaging apps , expanding the reach of an alert that, in emergency situations, can help to react quickly.
There is no confirmed release date; for now, the clue comes from the analysis of the Google Play Services 25.40.30 build shared by specialized media such as Android Authority, so the final implementation could change.
How the Android seismic alert system works
The Android Earthquake Alert System (AEAS) uses the accelerometer of millions of mobile phones to detect the first vibrations of an earthquake (P-waves) and act as a distributed network of mini-seismometers.
When several phones in an area detect that initial signal, they send data to Google's servers, which confirm the event and quickly calculate the epicenter and estimated magnitude to send the corresponding notification.
Compared to traditional networks based on dedicated physical seismometers , this crowdsourcing approach offers potentially wider coverage, although its effectiveness depends on the density of active Android devices in each region.
Types of notices and what information they display
Currently, the system issues two notification categories based on the expected intensity in your area, and each includes a different level of recommendation for the user.
- Be aware (Stay alert): designed for mild or low intensity jolts.
- Take action (Take precautions): oriented to moderate or strong movements and incorporates safety instructions.
The alerts include the estimated magnitude of the earthquake (starting at 4,5 on the Richter scale) and the approximate distance to the epicenter, as well as advice on how to act ; this service is available in Spain.
Why it can make a difference
The ability to manually share an alert transforms a personal protection tool into a community-wide warning, overcoming platform barriers and expanding the number of people informed in a matter of seconds.
Since its launch in 2020, the system has proven its usefulness in real-world incidents in countries such as Mexico, the Philippines, and Greece , and the collaborative function outlined in the code would reinforce that impact by making it easier for the alert to reach more recipients.
With this new development on the horizon, everything points to Google seeking to make critical information circulate more quickly and without depending on each user's operating system, something especially useful in contexts where every moment counts.
