Tunguska impact - HD 影片檔

"Animation of the comet impact at Tunguska. The Tunguska impact occurred on 30th June 1908, when an object, thought to be a comet, exploded above forest in Siberia, Russia. The explosion flattened trees over more than 2000 square kilometres. The explosion is thought to have been some 1000 times more powerful than the atomic bomb dropped on Hiroshima, with a power of some 15-20 megatons of TNT. The event released huge amounts of dust and water vapour into the upper atmosphere, which caused the sky to glow at night even far away from the region."
