Entire U.S. West Coast Now Covered By Earthquake Early Warning System
Cellphone users from the U.S. border with Canada south to the border with Mexico should receive a mobile alert from the early warning system when an earthquake is detected.
Residents living on the West Coast don't know when the next earthquake will hit. But a new expansion of the U.S. earthquake early warning system gives 50 million people in California, Oregon — and now Washington — seconds to quickly get to safety whenever the next one hits.
