Earthquake early warning alerts will become publicly available throughout California for the first time this week, potentially giving people time to protect themselves from harm, the Governor’s Office of Emergency Services said Wednesday, Oct. 16, 2019.

LOS ANGELES (AP) — The U.S. Geological Survey says the earthquake early warning system known as ShakeAlert will be capable of delivering alerts directly to wireless devices in Oregon on March 11 and to Washington state in May.

The USGS announced the target for completing the West Coast rollout on Tuesday.

The ShakeAlert system warns of significant quakes and has been enabled in California since October 2019.

The system uses a network of sensors that detect the start of an earthquake and calculates magnitude, location and the expected amount of shaking. It sends the information in real time to distributors that send out alerts to cellphones and the internet.
