two new holes in Siberia, the mystery remains
How many holes? This is the question posed in Siberia for several days. On July 15, the Times newspaper Siberian unveiled images of a curious crater formed in the Yamal Peninsula, the "end of the world" in the local dialect in northwest Siberia, washed by the Kara Sea. Opening with clean edges, which gives a large underground cavity, appeared on earth that usually remains frozen all year round (permafrost or permafrost in English), not far from one of the largest gas deposits Europe.
Reported by the journal, two new holes were discovered by reindeer herders, the few people that go to those areas. One of them, a diameter of 15 m, were a few hundred kilometers of the first, near the Yamal Peninsula, across the Gulf of Ob, Taz in the district. According to nearby residents, would have formed in September 2013, with explosive sound. The third crater, meanwhile, was far beyond the Taimyr Peninsula, east and north. This crater is a perfect cone, surrounding a central hole diameter of 4 m.
These holes they explain a feature of the landscape of the Yamal peninsula?
Scientists are very interested in this phenomenon and studies are carried out in the first crater discovered. According to Andrey Plekhanov's Arctic Research Center, this hole is formed there are one or two years. Teams work on images taken by satellites to determine. The snapshots have been made inside the cavity, which would be approximately 70 m deep. The fund, which was not achieved, appears full of ice. It seeps from the lips of the crater, it sinks to the bottom and then freezes. (See all pictures of the three sections of Siberia Times, whose links are grouped at the bottom of this article.).
The explanation of this phenomenon has not yet been written. According to Andrey Plekhanov, there was no explosion, as has been said. The soil around the hole was launched by "internal strength". The first possible cause is the unusually high temperature prevailing in the region this summer, as was the case in 2012 and 2013, but there is nothing at this time no reason to make this assumption to certainty. The researcher recalls a sense of the 1980s, and abandoned, that small lakes are typical of the Yamal peninsula, formed by a phenomenon of the same type. He said that if these things happen from time to time by 8,000 years, could explain the landscape of this region.
