"Tunguska event
From Wikipedia, the free encyclopedia

The Tunguska Event, or Tunguska explosion, was a massive explosion that occurred near the Podkamennaya (Lower Stony) Tunguska River in what is now Krasnoyarsk Krai of Russia, at around 7:14 a!.m!.[1] (0:14 UT, 7:02 a!.m!. local solar time[2]) on June 30, 1908 (June 17 in the Julian calendar, in use locally at the time)!.[2]

The explosion was most likely caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 miles) above Earth's surface!. Different studies have yielded varying estimates for the object's size, with general agreement that it was a few tens of metres across!.[3]"Www@QuestionHome@Com

The theories are:

Asteroid
Comet
Crashed UFO
Anti-Matter

An asteroid usually leaves a crater!. They think that it was possibly a small comet that exploded about 1-5 miles above the epicenter!. Recent studies of buried peat-moss in the area show small particles usually found in comets!.Www@QuestionHome@Com
