What Google Public Alerts does
Being prepared is just as important as knowing what to do in a crisis. Google Public Alerts provide a warning before disasters cause damage, and information on how to stay safe.
For providers of emergency alert data, Google offers tools, instructions, and support for delivering industry-standard warnings and recommendations, to the right people, at the right time.
Google Public Alerts are integrated with Google Search, Google Maps, and Google Now.
Results in Google Search
If you search for a place where there is a relevant active alert, or from within an affected area where there's a relevant active alert, you'll see a warning, and a link to click through to find out more information.
Local updates on Google Maps
If you're searching Maps on desktop or mobile, you'll get relevant alerts for that area. The Google Maps for Mobile app can also display a warning notification if there is a relevant alert nearby.
Notifications on Google Now
If there's a relevant active alert for your local area, you'll receive a notification to let you know what's going on, and where.
