"Google Public Alerts is Google’s platform for disseminating emergency messages such as evacuation notices for hurricanes, and everyday alerts such as storm warnings. We aim to show relevant official weather, public safety and earthquake alerts around the world when you search on Google Search, Google Maps, and when you activate Google Now on your Android device. Currently, we publish content from our partners in the U.S., Australia, Canada, Colombia, Japan, and Taiwan.
Google Public Alerts is a project of the Google Crisis Response team, supported by Google.org, which uses Google's strengths in information and technology to build products and advocate for policies that address global challenges. We hope Google Public Alerts provides the public with information it needs to make informed decisions in times of crisis."
