This paper begins by providing a brief geological history of the mountain, separating it into nine different periods. It then examines various lava types found in the area. The paper moves to modern day when the first actual threat was realized for eruption. It discusses the process of eruption and the different types of blast - lateral blast (direct blast zone, channelized blast zone, seared zone); vertical blast and pyroclastic flows. It concludes with an analysis of the aftermath and its effect on wildlife in the area.
From the Paper:"On May 18, 1980, Mount St. Helen's in southwestern Washington erupted with a massive explosion. Leading up to this day was increasingly intense earthquake activity. There were also lots of relatively weak eruptions and many locations of minuet gas discharge. The devastating impact of the suddenly unleashed volcanic energy caused the worst volcanic and geological disaster in the recorded history of the United States."
