Tunguska Anniversary 6-30-1908

100 years ago, today, a huge fireball descended near the remote town of Tunguska in Russia. The object was estimated to be 50 feet across and exploded 3-5 miles above the earth where it leveled an area of 830 square miles. People 100 miles away were knocked to their feet and and the explosion was equivalent to a yield of 10-15 megaqtons of TNT. There is still debate as to whether the object was a comet or a meteor. Amazingly, there were no fatalities due to the remote location. Had this occured in a larger city, the devastation would have been complete and far-ranging.
