With the Third Pixel Feature Drop at the beginning of June, Google added a bunch of new features to Android 10 on Pixel devices. Among these, Google added some improvements to the Personal Safety app by extending the Crash Detection feature from Pixel 4/4XL to Pixel 3 series and adding two new features – "Safety Check" to keep emergency contacts updated about your whereabouts if you don't respond to scheduled check-ins and "Crisis Alerts" to inform you of natural disasters in your area.

Although Crisis Alerts are not for any specific type of natural calamity, Google is preparing to add an alert mechanism specifically for earthquakes. We spotted references in the Google Play Services 20.26.12 beta that the company added for earthquake alerts specifically in California. These alerts are powered by ShakeAlert, a service that provides early warnings about earthquakes specifically for the West Coast.

In an APK teardown of the Google Play Services 20.26.12 beta, we found the following strings hinting towards the features and its applications:

The earthquake warning feature should share details including your distance from the epicenter, share tips on how to keep you safe as well as action points to follow in case you need to evacuate the premises.
