LOS ANGELES (AP) 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, completing the West Coast rollout, the U.S. Geological Survey said Tuesday.

As massive slabs of Earth squish into and grind past each other off the coast of the Pacific Northwest, many people may wonder when they will feel ensuing earthquakes. Although the U.S. Geological Survey cannot predict where and when future earthquakes will occur, the bureau, along with a team of organizations, helped create a system that can provide vital seconds of warning
Scientists watching tremors under Vancouver Island By David Rasbach, The Bellingham Herald

BELLINGHAM The Pacific Northwest Seismic Network is monitoring an “out of the ordinary” series of nearly 3,000 small seismic events over the past week that have rattled just northwest of Whatcom County under Vancouver Island.
“If you’ve checked the Tremor Map in the last couple days, you may have noticed an uptick in activity,” the network tweeted Tuesday morning. “Tremors in between ETS (episodic tremor and slip) events are normal, but starting on about Jan. 26th, tremor under Vancouver Island started getting stronger and longer over the next few days.”

A potential change to normal tremor activity in the Pacific Northwest is not typical, but experts do not believe it poses any greater risk.
Starting around Jan. 26, slow-slip events under Vancouver Island migrated back into an area that had significant tremor activity a few months ago, instead of filling an area that has been relatively quiet since early last year.
It appears the standard 14-month slow-slip events are covering similar areas, but are becoming scattered out over time.
