Mount St. Helens is one of the Cascade Volcanoes that reach from Washington to California. Before and After the Eruption Earthquakes caused by magma forcing its way to the surface, called harmonic tremors, preceded the blast.
Mount St. Helens is best known for its large explosive eruption, summit collapse and directed blast of May 18, 1980, which was the most expensive and deadly volcanic event in United States history. The volcano continued erupting during 1981-1986, producing a lava dome within the 1980 crater. Mount St. Helens last erupted in 2004-2008, when it produced a series of spectacular lava spines with a cumulative volume of almost 100 million cubic meters.
