As we reported a few days ago - at February 9 and February 12, 2012 in the Kuzbass, Kemerovo region, Russia, were observed two powerful explosions of unknown origin, with a magnitude of 3.6 and 2.6 on the Richter scale in the same place, and the new explosion with a magnitude of 3.7 on the Richter scale was occurred on February 15, 2012, a few hundred kilometers of to the east of the place of explosions, that were at February 9 and February 12, 2012. The cause of the new explosion on February 15, 2012, the Geophysical Service of Siberian Branch of Russian Academy of Sciences again, as well as the causes of explosions at February 9 and February 12, 2012, explained as the explosion (copy of the report message of Geophysical Service of Siberian Branch of Russian Academy of Sciences can be viewed at the top of this article). The explosion of February 15, 2012 took place in a deserted place of Siberia, far from human settlements and this new explosion completely rejects the all versions of the mining operations at the place of the explosion, as at the place of the new explosion were not conducted the mining operations. Despite the fact, that were versions, that this explosions were an ordinary earthquakes, but the experts of Geophysical Service of Siberian Branch of Russian Academy of Sciences as the causes of all these jarring of the earth's crust in Siberia at February 2012, were called the explosions on the surface of the earth, and did not an earthquakes, as the focus of conventional natural earthquakes could not located on surface of the earth. While none of the scientists can not explain the nature of these explosions, in the Kemerovo region continue to arrive a Russian scientists from Moscow and Novosibirsk, was established a special Commission for investigate of the causes of these explosions. Representatives of the Commission refuse to report about the causes of the explosions, but the online forums and social networks of the Kemerovo region is literally red-hot from the assumptions about the nature of these explosions, it is assumed, that the explosions were similar to the Tunguska explosion of 1908 or in this region were testing a new patterns of tectonic weapons.
