May is Volcano Awareness Month in Washington State. As we lead up to the 34rd anniversary of the May 18, 1980, eruption of Mount St. Helens, DNR Ear to the Ground is featuring one of our state’s five active volcanoes each day.
Glacier Peak. Located in a wilderness area in eastern Snohomish County, Glacier Peak is not easily visible from any major metropolitan centers, and so the hazards (and attractions) of this 10,451-foot peak may get overlooked. Yet, Glacier Peak has produced larger and more explosive eruptions than any other Washington volcano except Mount St. Helens. Glacier Peak is only 70 miles from Seattle, which puts it closer to the state’s largest metropolitan area than any volcano except Mount Rainier.
Eruptions of Glacier Peak have characteristically produced large volumes of volcanic ash and airborne pumice that could endanger the closest centers of population. The last major eruption of Glacier Peak was around the year 1700.
We want our awareness-raising about Washington State volcano threats to encourage preparation and not raise unnecessary alarm, so here is the very latest on alert levels for Cascade Range volcanoes from the U.S. Geological Survey Cascades Volcano Observatory.
DNR and its Division of Geology and Earth Resources help map, monitor and educate the public, governments and others about geologic hazards, including volcanoes.
