To turn off emergency alerts on an iPhone, follow these steps:

1. Open the Settings app.
2. Tap Notifications.
3. Scroll all the way to the bottom to find the Government Alerts section.
4. Here you will see toggles for different types of alerts such as AMBER Alerts , Public Safety Alerts , and Emergency Alerts.
5. Toggle off the alerts you want to disable, for example, turn off AMBER Alerts and/or Emergency Alerts.

This will stop those specific emergency alerts from appearing on your iPhone

. If you want to keep receiving emergency alerts but want to silence the loud alert sounds, you can do this:

• In Settings > Notifications, scroll down to Emergency Alerts.
• Tap it and toggle off Always Play Sound.
• This way, alerts will still come through but without the loud siren noise, especially if your phone is on Silent mode

Note that some carriers may restrict the ability to toggle these alerts on or off, so if you don’t see the Government Alerts section, it could be due to your carrier’s settings

. For newer iPhone models (like iPhone 16 series), emergency contact alerts can be managed separately via Settings > Apps > Messages > Notifications > Customize Notifications > Emergency Contact Alerts

. In summary, the main method is to go to Settings > Notifications > Government Alerts at the bottom, and toggle off the alerts you want to disable. If you only want to silence the sound, toggle off the "Always Play Sound" option under Emergency Alerts.
