There are several ways to get ShakeAlert-powered alerts on your cell phone. Water and gas utilities, transit systems, and emergency facilities like fire stations and hospitals alert staff to take a protective action such as Drop, Cover, and Hold On and trigger automated actions such as opening a fire house door so first responders can do their job. Many USGS partners across California, Oregon, and Washington already use ShakeAlert Messages to enhance public safety. To ensure that you can receive WEA alerts consult your cell phone instructions about receiving emergency alerts or contact your cell phone service provider. Alert delivery via the WEA system is available in California, Oregon, and Washington.

The USGS issues ShakeAlert ® Messages but alert delivery will come by other public and private means (internet, radio, television, cellular), including Wireless Emergency Alerts (WEA) - think of an AMBER Alert - delivered by FEMA’s Integrated Public Alert and Warning System (IPAWS).
