Next Tuesday is the 30th anniversary of the Mount St. Helen’s eruption that killed 57 people. The eruption’s blast wave and hot ash also killed thousands of wildlife and produced debris flows of mud and ash that destroyed homes, roads, and bridges. Hundreds of thousands of trees were blown down on DNR-managed land just a few miles away.
DNR’s geologists were among those who worked with the U.S. Geological Survey, other agencies and emergency officials following the May 18, 1980, eruption. See our Mount St. Helens information page with information and many links about volcanoes, including the Mount St. Helens National Monument.
QUESTION: What was the elevation of Mount St. Helens before the eruption and what was it after the eruption?
ANSWER: Find out tomorrow on Ear to the Ground …or… see the answer now on DNR’s Facebook page (while you’re there, please “fan us” — we’ve got plenty more information about Mount St. Helens coming in the next few days.)
