What is the USGS doing about earthquake early warning?
Earthquake early warning (EEW) is the rapid detection of an earthquake and issuance of an alert or notification to people and vulnerable systems likely to experience potentially damaging ground shaking.
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.
Learn how earthquake warning systems work, where they are deployed, and what benefits they provide. Compare different countries' systems, such as China, Japan, Mexico, and the US, and see examples of alerts and data.
Learn about USGS's research and development of earthquake early warning for the United States, and how to get alerts from ShakeAlert® system. Find out how other countries have implemented and used earthquake early warning systems.
Earthquake early warning systems don’t predict earthquakes. Instead, they detect ground motion as soon as an earthquake begins and quickly send alerts that a tremor is on its way, giving people crucial seconds to prepare.
Learn how earthquake early warning works, who can benefit from it, and how to get the MyShake app. See how BART and other institutions use ShakeAlert, the public system based on UC Berkeley's ElarmS algorithm.
