Alerts will be triggered for earthquakes with a magnitude of 4.5 or greater, providing users with critical details such as estimated magnitude and distance to the epicenter.

Significant shaking alerts will override volume and Do Not Disturb settings, emitting a loud sound and offering safety advice on screen.

There are two types of alerts: a 'Be Aware Alert' for light shaking that does not disrupt silent modes, and a 'Take Action Alert' for stronger quakes that triggers loud alarms and displays safety tips.

The earthquake detection system utilizes accelerometers in Android phones as mini seismometers to identify quakes based on crowdsourced data.

This feature is especially advantageous for smartwatch users with cellular models, as they may not always carry their phones during outdoor activities.

Google is set to enhance its Android earthquake alert system by extending it to Wear OS smartwatches, enabling users to receive seismic activity warnings directly on their wrist.

This rollout is part of the June 2025 Google Play services update, which is expected to improve emergency preparedness for users in earthquake-prone areas.

The feature is particularly beneficial for residents in regions like California, Japan, the Philippines, and Turkey, allowing for quicker response times during natural disasters.

According to the Google System Release Notes, users will receive alerts when an earthquake is expected to cause shaking.

The latest update supports devices in 98 countries, indicating a broad reach for this life-saving technology.

While Google has not officially announced the rollout, indications of the feature's implementation were discovered in an earlier APK teardown.

Google Play services updates for both phones and wearables will be applied automatically in the coming days.
