Google is bringing its Android earthquake alerts to Wear OS smartwatches. The feature, which uses phone sensors to detect seismic activity and send early warnings, will now alert users directly on their watches. This update is rolling out with Google Play Services version 25.21. Alerts will show estimated magnitude and distance to the epicenter, just like on phones. While not officially announced, this addition has been expected since earlier leaks and is especially useful for users who leave their phones behind.
