CXA001 Posted May 1, 2014 Report Share Posted May 1, 2014 On May 18th, 1980 at 8:32pst, Mount St. Helens after 2 months of increased seismic activity, catastrophically erupted. The eruption triggered an earthquake measuring 5.1 on the Richter scale causing the North face to collapse into the Columbia River basin and reducing the mountain’s summit elevation from 9,677 ft to 8,365 ft. By 17:30pst that evening after more than 9 hours of a vigorous plume of ash, reaching 16 miles above seas level, the ash column began to decline. On that day 34 years ago this month, Mount St. Helens released 24 megatons of thermal energy, 1.5 tons of sulfur dioxide and 2.8 cubic kilometers of debris. Sadly the event also killed 57 people, and nearly 7000 big game animals from the mountain area.
