Time-Lapse Video Shows Volcanic Activity of Mt. St. Helens Eruption

Mt. St. Helens Eruption Video

Located in Skamania County, Washington, Mount St. Helens is ranked as a person of the most perilous volcanoes in the United States. Its most popular eruption in 1980 is viewed as to be the most lethal and harmful volcanic celebration in the record of the U.S. In the aftermath, hundreds of properties were shed, 57 individuals dropped their life, 47 bridges were being destroyed, and hundreds of miles of freeway and railways have been broken. The eruption also still left a massive crater at the volcano’s summit, lowering its general peak by 1,314 feet.

Mt. St. Helens continued to screen symptoms of moderate volcanic activity, from the time of its catastrophic 1980 eruption effectively into the early 90s. However, it commenced to clearly show major signals the moment once again in Oct 2004. This period of activity ongoing for four decades, with the magma from the eruption constructing a new lava dome in the middle of the volcano’s gaping crater—as if the mountain was rebuilding itself from the within out.

According to John Eichelberger, a volcanologist at the University of Alaska-Fairbanks, Mt. St. Helens is essentially “a huge tube of toothpaste, squeezing out lava.” Owing to the mountain’s condition, the magma does not have any room to obtain. In its place, it finds a route to the floor and commences to ooze out, forming a “spinelike” dome in the volcano’s crater.

Throughout the eruption, the United States Geological Survey (USGS) positioned a camera in close proximity to the volcano to capture a time-lapse video clip of the activity. The corporation revealed the a long time of footage, condensed down into an 86-2nd video clip that shows the astonishing level at which the lava dome grew amongst 2004 and 2008. About the 4-yr period, around 125 million cubic yards of lava gushed into the crater, forming the new dome.

“The initial phase made quick growth of a lava dome as magma pushed upward,” the USGS points out. As revealed in the movie, an initial succession of lava spines, two recumbent and just one steeply sloping, grew to approximately 500m [1,640 ft] in size just before disintegrating into mounds of rubble.”
