Mount St. Helens monitoring ongoing 36 years after eruption
MOUNT VERNON, Wash. (AP) — Thirty-six years after a deadly volcanic eruption at Mount St. Helens, the United States Geological Survey is still closely monitoring the volcano and others in the state.
The Skagit Valley Herald reports (http://goo.gl/sf96ct ) the USGS monitors volcanoes in Washington and Oregon’s North Cascades region through its Cascades Volcano Observatory and activity this year has been considered normal. The agency issues weekly reports on seismic activity near the volcanoes.
Washington’s five major volcanoes are Mount Rainier, Mount Adams, Mount Baker, Mount St. Helens and Glacier Peak.
Mount St. Helens erupted on May 18, 1980, killing 57 people and eventually sending volcanic ash around the globe.
