Giant Earth Fart: Party Prank Gone Horribly Wrong?
On June 30, 1908, a large segment of the Tunguska forest in Siberia experienced some kind of spectacular explosion. Trees were flattened, and there was a major conflagration. The force has been estimated as the equivalent of a 50 megaton hydrogen bomb.
The most popular scientific explanation has been a meteorite impact. (Other theories include aliens and so forth.) Now, in charmingly imperfect English, we read a Siberian scientist's alternate theory.
The scientist assumes that the gases associated with the oil deposits, and methane produced in the depths of coal beds were accumulated under a thick cover of basalts and then they broke free one day....
The gas kick started nine days prior to the major explosion, a narrow jet of gases rushed up southbound. The fluid jet from under the earth was accompanied by dust, and the wind carried the dust to the west. In the upper layers of atmosphere a layer of aerosols was formed. This layer charged with electricity could have produced the fatal 'sparkle'. It put on fire the top of the liquid jet, and the fire ball rushed towards the Earth. In the oxygen saturated layer of atmosphere the fire ball exploded, the blast wave stirred up the ground, and the gas discharge ceased.
