How to Enable Android Earthquake Alerts in 200+ Regions

A few seconds of warning can let you drop, cover, and hold on before strong shaking arrives. Google expanded the Android Earthquake Alerts System on October 15, 2026, from 98 countries and regions to more than 200, including Panama and Guatemala.

The system has already sent more than one billion alerts since 2021. It now covers far more people who previously had no early-warning option.

This guide shows how to confirm the feature is on, what each alert type means, and how the system works so you can use it when it matters.

How Android Earthquake Alerts Work

Android phones contain accelerometers—the same sensors that rotate your screen. When a stationary phone detects the faster primary (P) wave of an earthquake, it sends a coarse location signal to Google’s servers.

Servers combine reports from many phones to confirm an event, estimate location and magnitude, and decide who needs an alert. In California, Oregon, and Washington the system also distributes alerts from the USGS ShakeAlert network.

Alerts go out only for events of roughly magnitude 4.5 or greater. You need an internet connection (Wi-Fi or mobile data) and location services enabled. The system uses privacy-preserving coarse location data.

Google reports the system has detected more than 18,000 earthquakes and issued alerts for more than 2,000 of them.

Three Alert Types You May See

If an earthquake is detected in a covered region, your phone shows one of three alerts:

• Be Aware — Estimated light shaking. A standard notification that an earthquake has been detected nearby.
• Be Ready — Estimated stronger shaking. A more detailed alert that tells you to prepare to take action. Google is adding a map with a shaking radius, estimated magnitude, and recommended actions in the coming months.
• Take Action — Estimated moderate to heavy shaking. A full-screen alert with a loud sound that overrides Do Not Disturb and gives immediate safety advice.

The Take Action alert is designed to be impossible to miss. Be Aware and Be Ready are less disruptive so they can still reach people farther from the epicenter.

Check and Turn On Earthquake Alerts

Most Android devices turn the feature on by default where it is supported. Still, verify the setting after a system update or if you bought a used phone.

1. Open the Settings app.
2. Search for “earthquake” or go to Safety and emergency (sometimes under Location → Advanced on older versions).
3. Tap Earthquake alerts.
4. Make sure the toggle is on.
5. Tap the demo button if available so you know what the sound and screen look like.

On Samsung phones the path is usually Settings → Safety and emergency → Earthquake alerts. If you cannot find it, search Settings for “earthquake.”

Also confirm:

• Location services are on.
• The phone has a data connection.
• Google Play Services is up to date.

You can pair this with other Android safety features. See our guide on how to turn on Advanced Protection on Android 16+ for broader device hardening.

What to Do When an Alert Arrives

Be Aware or Be Ready

Note the information and stay ready. Move away from windows or heavy objects if you can do so quickly. The new Be Ready details (map, magnitude, actions) will appear in the coming months.

Take Action

Follow the on-screen instructions immediately. The standard advice is Drop, Cover, and Hold On:

• Drop to your hands and knees.
• Cover your head and neck under a sturdy table if possible.
• Hold on until the shaking stops.

If you are outside, move to an open area away from buildings, trees, and power lines. If you are driving, pull over safely and set the parking brake.

After the shaking ends, the alert often provides a link to more information. You can also search Google for “Earthquake near me” to see official details.

Tips for Reliable Alerts

Keep the phone charged and connected. Alerts require network access; a phone in airplane mode or with no signal will not receive them.

The system works best when many phones in an area are stationary and reporting. Dense urban areas tend to get faster confirmation.

False alarms have been rare. Google has refined the models after earlier acoustic events such as thunderstorms produced a small number of incorrect detections.

If you travel, the feature follows your phone. Coverage expands as Google adds more regions, so the same toggle works in newly supported areas.

For extra safety layers on Pixel or Galaxy devices, review theft-protection settings and Play Protect. Those tools do not replace earthquake alerts but reduce other risks.

Limitations to Know

Android Earthquake Alerts do not replace national systems where they exist. In Japan, Mexico, or the US West Coast, official seismic networks still provide the fastest and most precise warnings; Android distributes those alerts in addition to its own phone-based detections.

The system cannot warn everyone. Phones must be on, have data, and be in a covered region. Very close to the epicenter the warning time can be only a few seconds—or the alert may arrive after shaking starts.

iPhone users rely on government Wireless Emergency Alerts or national systems in supported countries; they do not participate in the Android phone-sensor network.

Google continues to improve detection accuracy and alert content. The expanded Be Ready map and magnitude details are rolling out in the coming months.

Conclusion

Enabling Android Earthquake Alerts takes under a minute and can give you critical seconds in more than 200 regions. Confirm the toggle is on, know the difference between Be Aware, Be Ready, and Take Action, and practice the Drop, Cover, and Hold On response.

The system has already delivered more than one billion alerts. With the October 2026 expansion, more people now have access to early warnings that were previously limited to a few dozen countries.

Keep the feature enabled, keep your phone connected, and treat every alert as a prompt to protect yourself and those around you.
