What is ShakeAlert®?
The ShakeAlert® Earthquake Early Warning (EEW) System, managed by the U.S. Geological Survey, detects significant earthquakes quickly enough so that alerts can be delivered to people and automated systems potentially seconds before strong shaking arrives. ShakeAlert is the nation’s only public EEW system and it serves over 50 million residents and visitors in California, Oregon, and Washington. The purpose of the ShakeAlert System is to reduce the impact of earthquakes to save lives and property.
The USGS works with licensed technical partners who use USGS-issued ShakeAlert Messages to alert people to take a protective action or to trigger automated actions. These automated actions could include slowing trains, closing water valves, turning on backup generators, issuing public announcements, and many others.
