June 30, 1908 –
An explosion near the Tunguska River in Siberia on this date, incinerated some 300 sq. km. that encircled the impact of an estimated 60 meter diameter stony meteorite. It flattened some 40,000 trees over 900 sq. miles and caused damage equivalent to a 15-megaton hydrogen bomb.
The explosion in Siberia, which knocked down trees in a 30-mile radius and struck people unconscious some 40 miles away, is believed by some scientists to be caused by a falling fragment from a meteorite.
