- ShakeAlert – Because seconds matter.
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
- Introduction – ShakeAlert
To advance this goal, the USGS has developed this ShakeAlert Tests, Drills, and Exercises Toolkit to incorporate earthquake early warning (EEW) into existing training activities
- Post ShakeAlert® Message Summaries
They summarize how accurately the ShakeAlert system estimated an earthquake’s location, magnitude, shaking intensities, how much warning time for selected nearby cities, and how many seismic stations contributed data to these estimates
- Alert Delivery Thresholds – ShakeAlert
End-users in California, Oregon, and Washington receive ShakeAlert-powered alerts only if certain thresholds for magnitude and shaking intensity are met, as identified below
- ShakeAlert® Messaging Toolkits – ShakeAlert
ShakeAlert ® Messaging Toolkits augment existing earthquake preparedness efforts, offer consistent information about ShakeAlert Earthquake Early Warning System technology, and promote protective actions
- ShakeAlert® System Algorithms
The ShakeAlert System includes the USGS component, plus the pathways by which ShakeAlert-powered products and services are delivered to end-users, such as alerts to a cell phone or computer systems that trigger an automated action, such as slowing or stopping trains
- Toolkit – ShakeAlert
To advance this goal, the USGS has developed this ShakeAlert Tests, Drills, and Exercises Toolkit to incorporate earthquake early warning (EEW) into existing training activities
- ShakeAlert® Ready – ShakeAlert
ShakeAlert, the nation’s only public earthquake early warning system, provides potential seconds of warning when strong shaking is expected
