Mount St. Helens Mount St. Helens or Louwala-Clough (known as Lawetlat'la to the indigenous Cowlitz people, and Loowit to the Klickitat) is an active stratovolcano located in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 96 miles (154 km) south of Seattle, Washington, and 50 miles (80 km) northeast of Portland, Oregon. Mount St. Helens takes its English name from the British diplomat Lord St Helens, a friend of explorer George Vancouver who made a survey of the area in the late 18th century.[1] The volcano is located in the Cascade Range and is part of the Cascade Volcanic Arc, a segment of the Pacific Ring of Fire that includes over 160 active volcanoes. This volcano is well known for its ash explosions and pyroclastic flows.
1980 eruption of Mount St. Helens The May 18, 1980, event was the most deadly and economically destructive volcanic eruption in the history of the United States.[6] Approximately fifty-seven people were killed directly from the blast and 200 houses, 47 bridges, 15 miles (24 km) of railways and 185 miles (298 km) of highway were destroyed; two people were killed indirectly in accidents that resulted from poor visibility, and two more suffered fatal heart attacks from shoveling ash.[29] U.S. President Jimmy Carter surveyed the damage and said it looked more desolate than a moonscape.[30][31] A film crew was dropped by helicopter on Mount St. Helens on May 23 to document the destruction. However, their compasses spun in circles and they quickly became lost.[32] A second eruption occurred the next day (see below), but the crew survived and were rescued two days after that. The eruption ejected more than 1 cubic mile (4.2 km3) of material.[33] A quarter of that volume was fresh lava in the form of ash, pumice and volcanic bombs while the rest was fragmented, older rock.[33] The removal of the north side of the mountain (13% of the cone's volume) reduced Mount St. Helens' height by about 1,280 feet (390 m) and left a crater 1 to 2 miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach.[33]
