Set up emergency alerts
To get earthquake alerts, tsunami alerts, and other disaster information on your iPhone or Apple Watch,* follow these steps:
- Tap Settings > Notifications.
- Scroll down to the bottom of the screen.
- Tap Emergency Alerts to turn them on or off.
* If you have an iPhone 4, you can only get earthquake alerts and tsunami alerts. iPhone 3G or iPhone 3GS can only receive earthquake alerts. Alerts are supported when using a SIM card from a supported carrier. Your Apple Watch can receive these alerts if your iPhone can receive them and is nearby, or your Apple Watch is on a Wi-Fi network. With a cellular plan from a supported carrier, your Apple Watch Series 3 (GPS + cellular) can receive these alerts without your iPhone nearby. For more information, contact your carrier.
