2 Mount St. Helens 1980 Eruption Small earthquakes Small steam and ash eruptions in March and April 1980 USGS monitoring station set up north of the mountain on Coldwater Ridge May North side of mountain began to bulge, many micro-earthquakes, eruption was imminent; red-zone closed See USGS Professional Paper 1250 (1981) for much more information and pictures

4 8:32 AM 5/18/80 Magnitude 5.1 earthquake triggered the Big Eruption The unstable bulge on the North side collapsed and exposed magma in a shallow chamber to air Gas bubbles formed instantaneously in the magma causing expansion, a shock wave and a big ash eruption Most of the force of the eruption was directed horizontally to the North Only 57 people died in the eruption

29 Mount St. Helens 2004 October 1, A small explosive eruption of Mount St. Helens on October 1st; the first in more than a decade followed a week of increasing earthquake activity beneath the volcano and deformation of the lava dome. This eruption sent a steam and minor ash plume to an altitude of about 10,000 feet above sea level.
