Tunguska Blast

On June 30th, 1908 the most powerful explosion in recorded history took place, and we’re still not certain as to what caused it. The Tunguska Blast exploded with 185 times more energy than the Hiroshima atomic bomb, leveled 772 square miles of forest, flattened roughly 80 million trees and shattered windows in the nearest town located 35 miles away. Residents of the town even felt the heat from the blast and several were knocked from their feet. Researchers today point to an asteroid, but there is no recorded impact crater and very few traces of extraterrestrial objects have been recovered.
