On Android, emergency alerts are sent through the Wireless Emergency Alerts (WEA) system. WEA is a government-run system that allows authorized senders to send messages to cell phones in specific areas.

When you receive an emergency alert, your phone will make a loud noise and display a message on the screen. The message will include information about the emergency, such as the type of emergency, the location of the emergency, and what people should do to stay safe.

You can turn emergency alerts on or off in your phone's settings. To do this, open the Settings app and go to Notifications > Wireless emergency alerts.
