The Tunguska Event, A Mysterious And Devastating Explosion
The Tunguska Event occurred on June 30, 1908. The explosion leveled about 800 square miles (2,000 square kilometers) of remote Siberian forest, knocking over trees and sending shockwaves across the continent. One man was thrown from a chair on the porch of a trading post 40 miles (64 kilometers) away. He described the event in terrifying terms: "...The sky was split in two, and high above the forest the whole northern part of the sky appeared covered with fire...At that moment there was a bang in the sky and a mighty crash...The crash was followed by a noise like stones falling from the sky, or of guns firing. The earth trembled."
