ShakeAlert early warning system adds real-time satellite data to improve earthquake detection [Video]

SEATTLE — The United States Geological Survey (WSGS) announced Wednesday that its ShakeAlert System, which alerts the public before an earthquake begins, will add real-time satellite data to improve its early detection warnings. 

In addition to over 1,500 seismic sensors used to detect ground shaking, the ShakeAlert system will use sensors that detect earth-surface movement via satellite.

The WSGS said in a release the system’s new capability will use data from real-time Global Navigation Satellite System sensors, improving scientists’ ability to quickly and accurately determine the magnitude and area of shaking from large earthquakes. In turn, this will result in faster notifications for people to take protective action, such as “Drop, Cover, and Hold On.”

The ShakeAlert System, currently available in California, Oregon and Washington, can protect people and infrastructure by delivering alerts to cell …
