The USGS ShakeAlert Earthquake Early Warning System uses earthquake science and technology to detect significant earthquakes quickly so that alerts can reach many people before shaking arrives. The seconds to tens of seconds of advance warning can allow people and systems to take actions to protect life and property from destructive shaking.

Revised technical implementation plan for the ShakeAlert system—An earthquake early warning system for the West Coast of the United States

The U.S. Geological Survey (USGS), along with partner organizations, has developed an earthquake early warning (EEW) system called ShakeAlert for the highest risk areas of the United States: namely, California, Oregon, and Washington. The purpose of the system is to reduce the impact of earthquakes and save lives and property by providing alerts...

Earthquake Early Warning ShakeAlert System: Testing and certification platform

Earthquake early warning systems provide warnings to end users of incoming moderate to strong ground shaking from earthquakes. An earthquake early warning system, ShakeAlert, is providing alerts to beta end users in the western United States, specifically California, Oregon, and Washington. An essential aspect of the earthquake early warning...

Earthquake early Warning ShakeAlert system: West coast wide production prototype

Earthquake early warning (EEW) is an application of seismological science that can give people, as well as mechanical and electrical systems, up to tens of seconds to take protective actions before peak earthquake shaking arrives at a location. Since 2006, the U.S. Geological Survey has been working in collaboration with several partners to...
