Android Earthquake Alerts Expand to 200+ Regions

Android earthquake alerts now cover over 200 regions with updated Be Ready details. Learn how they work and how to check your settings.

Google expanded its Android Earthquake Alerts System on 15 October 2026. The system now covers more than 200 countries and regions, up from 98. It has already sent over one billion alerts since launching in 2021.

A few seconds of warning can give you time to drop, cover, and hold on before stronger shaking arrives. The update also improves the Be Ready alert with maps, magnitude estimates, and clearer guidance in the coming months.

This guide explains how the system detects earthquakes, the three alert types, how to confirm it is enabled on your phone, and what the expansion means for users.

How Android Phones Detect Earthquakes

Every Android phone has an accelerometer. This sensor detects motion and orientation changes, such as rotating the screen or counting steps. When a phone sits still, the same sensor can pick up the initial P-wave of an earthquake.

P-waves travel faster than the damaging S-waves. Stationary phones near the epicenter send a coarse location signal to Google’s servers. The system aggregates reports from many devices to confirm an event, estimate its location and magnitude, and decide who should receive an alert.

In California, Oregon, and Washington the system partners with ShakeAlert, which uses traditional seismic sensors. Everywhere else it relies on the crowdsourced phone network. Google describes this as the world’s largest mobile-based earthquake detection network.

Alerts require Wi-Fi or mobile data and location services enabled. The feature ships through Google Play services and works on Android 9 and later.

Three Alert Types and the New Be Ready Details

When an earthquake of magnitude 4.5 or greater is detected in a covered region, Android users see one of three alerts based on expected shaking intensity:

Be Aware — A standard notification for estimated light shaking. It lets you know an earthquake has been detected nearby.
Be Ready — A more detailed alert for stronger shaking that tells you to prepare to act. Google is adding a map showing the radius of detected shaking, an estimated magnitude, recommended actions, and a button for more information as data arrives.
Take Action — A full-screen alert for moderate to heavy shaking. It plays a loud sound, can override Do Not Disturb, and gives immediate safety advice such as drop, cover, and hold on.

The Be Ready improvements roll out over the coming months. Until then, the existing alert types continue to function. Google notes that these alerts supplement, and do not replace, official government warning systems.

How to Check and Enable Earthquake Alerts

Earthquake alerts are usually on by default in supported regions. You should still confirm the setting and test the sound.

Open the Settings app on your Android phone.
Tap Safety and emergency (or search for “earthquake”).
Select Earthquake alerts.
Make sure the toggle is on. Tap See a demo to hear the alert tone and view the on-screen message.

The exact menu path varies slightly by manufacturer. On Samsung devices look under Safety and emergency. On older Android versions it may sit under Location > Advanced. Location services and an internet connection (Wi-Fi or mobile data) must stay enabled for alerts to arrive.

After an event you can tap the alert for tips on what to do next. Searching “Earthquake near me” in Google also shows recent information from the system.

What the Expansion Means

The jump from 98 to more than 200 regions includes places such as Panama and Guatemala. Rollout to newly supported areas began on 15 October and should finish within about a week.

Google says the system has already helped people in regions without dense traditional seismic networks. A Science paper from 2025 reported that over three years the network detected hundreds of earthquakes per month and delivered alerts that many recipients felt before or during shaking.

Coverage still depends on having enough stationary Android phones nearby to detect the P-wave. Near the epicenter the warning window can be very short. Farther away it can stretch to tens of seconds or longer.

Tips for Using the Alerts Effectively

Keep location services on and maintain a data connection. Test the demo alert so the sound is familiar. Practice the drop-cover-hold response so the seconds of warning are useful.

Treat the alerts as one layer of preparedness. Official local warning systems, if available, remain important. After an alert, check Google Search or trusted news sources for updated magnitude and impact information.

If you travel, the system follows your phone into covered regions. No extra app is required.

Conclusion

Android Earthquake Alerts now reach more than 200 regions and have delivered over one billion warnings. The upcoming Be Ready improvements add maps and magnitude estimates so the few seconds of advance notice become more informative.

Confirm the setting on your phone, test the demo, and know the three alert types. Those steps take less than a minute and can make the system more effective when it matters.
