What is ShakeAlert®?
The ShakeAlert® Earthquake Early Warning 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 operates in California, Oregon, and Washington and serves over 50 million residents and visitors in those states. The purpose of the 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.
