DARRINGTON — The U.S. Forest Service has given the green light to install new seismometers on Glacier Peak, classified as one of the most dangerous volcanoes in the United States.
There’s only one monitor there now, according to federal agencies. More early warning sensors could provide precious time to evacuate, the Everett Herald reported.
The U.S. Forest Service determined the project would have no significant impact on the environment. Two groups opposed the use of helicopters in a wilderness area. The Forest Service considered a “full range of alternatives” in making the decision to move forward. Crews carry equipment in backpacks, cutting down on flight time.
The U.S. Geological Survey can start installing four new monitors and upgrade the old one, as part of a 30-year special use permit. Government officials estimate the GPS stations could detect eight times as many earthquakes.
