The U.S. Geological Survey is greatly increasing funding for the region's seismic network, putting it on track to send public alerts of impending earthquake shaking within the next two years, the network's director said.

The federal agency gave $10.4 million to the Pacific Northwest Seismic Network (PNSN) for the next two years. The University of Washington and University of Oregon, which jointly operate the network, will receive $7.3 million and just over $3 million of that funding, respectively, said PNSN director Harold Tobin, who is also a professor in UW's Department of Earth and Space Sciences.

Funding - PNSN - Stations - Washington - State

The additional funding will help PNSN add 104 more seismic stations. It operates about 200 in Washington state now. The state of Washington has provided funding for 36 more stations, Tobin said. Another 70 stations would deliver optimal performance, he said.

Each station improves the speed, reliability and accuracy of the ShakeAlert early warning network, which PNSN operates in the Northwest.

Earthquakes - Region - Size - Amount - Delay

"It will help us detect earthquakes all over our region down to size and with the minimum amount of delay," Tobin said.

Even without the ideal number of seismic stations, a pilot version of the system performed well during...
