Mount St. Helens -- From the 1980 Eruption to 2000, Fact Sheet
March 16 May 17, 1980. The first sign of activity at Mount St. Helens in the spring of 1980 was a series of small earthquakes that began on March 16. After hundreds of additional earthquakes, steam explosions on March 27 blasted a crater through the volcano's summit ice cap. Within a week the crater had grown to about 1,300 feet in diameterWhen Mount St. Helens erupted, it left hundreds of square miles of what appeared to be a barren wasteland.
