Volcano Eruption – The Eruption of Mt St Helens 1980

In 1980, a major volcanic eruption occurred at Mount St. Helens, a volcano located in Washington, in the United States. The eruption (which was a VEI 5 event) was the only significant one to occur in the contiguous 48 U.S. states since the 1915 eruption of Lassen Peak in California.[1] The eruption was preceded by a two-month series of earthquakes and steam-venting episodes, caused by an injection of magma at shallow depth below the volcano that created a huge bulge and a fracture system on the mountain's north slope.
