Italian scientists identify impact crater; UK scientist says no way

Researchers from the University of Bologna are claiming that Lake Chelo in Siberia occupies a crater resulting from the most violent visitation by extraterrestrial debris in modern Earth history. Meanwhile, a source at Imperial College in London says that circumstantial evidence argues against the possibility.


In the Tunguska event in 1908, a comet or asteroid is believed to have exploded five to 10 kilometers (three to six miles) above the surface of the earth. The estimated force was equivalent to 20 million tons of TNT, or 1,000 Hiroshima bombs.
The London source says that the presence of ancient living trees around the perimeter of the lake and the shape of the bowl in which the lake sits argue against the idea of a large rock remnant striking ground and generating what would later become Lake Chaka.
The Italian team, on the other hand, onthe other hand, claiums that a “soft” impact could account for the terrain features observed in the vicitinity of the lake, and plans to return next year to investigate further.

    I have seen comments on one of Russian news sites that lake Cheko was thoroughly investigated in sixties by scientists from Tomsk State University and they did not find any evidence of lake’s extraterrestrial origin.
