Mysterious blast is early in the morning June 30, 1908 near the Stony Tunguska River, for over a hundred years is haunted by the researchers. Recently, a group of experts from the University of Bologna found in the center of Lake Cheko, located eight kilometers from the epicenter of the explosion, a strange anomaly, which may be a fragment of a celestial body.
Tunguska — a common name the three largest right tributary of the Yenisei River: Upper (Angara), Average (Stony) and Lower. In the area of the Stony Tunguska River near the village of Vanavara June 30, 1908 around 7:00 am saw a large fireball overflying the Yenisei basin area from the south-east to north-west (the alternative certification, the body had a cylindrical shape). Mission ended rolling deafening blast of the taiga at the height of seven to ten kilometers.
The powerful blast wave observatory recorded worldwide. The flash of light was observed at a great distance — bursting into a ball of fiery column height of about 20 kilometers. In more than two thousand kilometers of trees were knocked down, and in the houses, located hundreds of kilometers from the epicenter of the explosion blew out windows.
Ironically, in 13 years no one has dared to carry out studies on the site of the explosion. Only in 1921, enthusiastic and romantic fellow of the Mineralogical Museum in Moscow, Leonid A. Kulik, accidentally learned of the Tunguska mystery of old sheet tear-off calendar, seriously burned by it. With the support of Academician VI Vernadsky and Fersman he organized the first expedition to the area of the Stony Tunguska.
Kulik and his associates have collected more than 230 pieces weighing more than 200 pounds. But these were fragments of meteorites, previously fallen in the forest. In addition, the expedition found microscopic silicate and magnetite balls, as well as fragments of rocks with a high content of the elements of a possible cosmic origin of the substance. But has not been established whether this is due to the above events.
At present there are about 120 scientific, pseudo-scientific and pseudo-scientific hypotheses to explain the nature of the Tunguska event. The most common of them — the fall of the meteorite (presumably iron) or passing meteor swarm — quickly has been questioned, because it could not find the meteorite fragments.
Despite doubts about the nature of the meteorite explosion, enthusiasts continue to search for the crater (or craters) in the alleged epicenter. And it is not in vain.
So, in 1994, participants in the research association "Kosmopoisk" B. Romeyko able to make a successful aerial Stony Tunguska region. In pictures clearly see the outlines of the mysterious lake, located a few dozen kilometers from the proposed ground zero.
Round lake, with an area — 200 to 250 meters. The banks of the reservoir are covered by forest, where the trees were pushed down … As taiga around difficult to pass, this place was previously almost nobody knows. According to the hypothesis B. Romeyko, it is a water-filled crater of meteoritic origin.
For another "crater" ran in 2007, researchers from Bologna, led by an expert on marine geology Luca Gasperini. Italians noticed Ceco taiga lake that lies eight kilometers north-west of the proposed ground zero. The location of the reservoir coincides with the flight path of the giant body, which later for no particular reason was called the Tunguska meteorite. Curiously, Lake Cheko unchecked on any map, made before 1929, and according to the testimony of local residents, before the crash in 1908 it did not exist …
The project "Tunguska 99" Gasperini and his colleagues conducted a study of the lake area. First of all, they are struck by its almost right hemispherical shape. It was also found that the bottom of the reservoir has a conical shape, and its maximum depth is 50 meters. This may indicate that something huge been in this tunnel, and it took place in the ground. Indeed, the ground penetrating radar recorded a large object at a depth of 10 meters below the bottom of the lake.
Italian researchers suggest that the "culprit" was a fragment of the reservoir formation exploding cosmic body. Weight "splinter" in this case is about 1.5 × 106 pounds.
But, somehow, finds "craters" are so far just speculation. To date in the Stony Tunguska did not find any items about which it is safe to say that they are related to the long-time events …
