Location of the largest volcanic
eruptions in the last 25 million years, which almost destroyed the entire human
race began in 1980, Mount St. Helens in Washington spit a plume of smoke 80,000
feet high, people were killed and
57,200 houses destroyed, 27 bridges, 15 miles of track and 185 miles from the
highway. It was deadly and destructive
eruption most economically volcanic history of the United States.
For comparison, the largest
volcanic eruption in recorded historic times, the eruption of Tambora in 1815. He was eighty times more
powerful than Mount St. Helens and spat about 100 km3 of rock and the entire
northern hemisphere is dark and cold for all of 1816, making it the "year
without summer" , as we have known. But compared to the case who
participated in North Sumatra, Indonesia around 73,000 years ago, this was as
good as nothing.
Known as the event they Toba
ejected almost 2800 km3, or 28 times the largest volcanic eruption in
historical memory, and more than two thousand times more powerful than Mount
St. Helens. It was like the Yellowstone
supervolcano "big" sister, and when these mega-colossal volcanic
levels 8 - the highest rating on the volcanic explosivity index - burst was the
largest volcanic eruption in the last 25 million years.
It can have almost destroyed the
human race.
