Since finding the first crater in 2014, Russian scientists have documented 16 more explosions in the Arctic caused by gas trapped in thawing permafrost.
Moscow — A natural phenomenon first observed by scientists just six years ago and now rereading with dangerous frequency in Siberia is due to the earth being 100 feet deep, leaving craters with extraordinary and tremendous force.
When Yevgeny Chowalan, a Moscow-based geoscientist with the Skolkovo Institute of Science and Technology, arrived at the edge of the site this summer, the latest explosion, called The Thread 17, "it left enough impression."
The pit is surrounded by the queen, table flat, the fitorelissis tandra in the dark. He stood by watching Mr. Chowalan, the dirt and ice slab sometimes turned away from the wall and marble perma-roast.
"It was making noise. It was like something alive," Mr. Chowalan said.
In a secret initial, scientists have established that underground gases appearing in the north of western Siberia are the cause, and the current eruption is likely related to global warming, Craters said. "
Since the first site was found in 2014, Russian geologists have located 16 more on The Yamal and Gdansk Panansolus, pulling its two thin fingers into the Arctic Sea.
"In Canada and Alaska and are also affected by global warming," Mr. Chowlan said.
The explosions are home-made on small hills or tandra where the gas from the waste organic matter gets trapped underground.
The top is present under a snow-covered sand and all around the perma-fast, gas pressure that creates the waste of the soil of the behavior. Explosions occur when the pressure increases or the ice sheet is blown and suddenly breaks.
"Where gas comes from is a matter of debate," Said Chowalan, who said that the permafrost is covered by well-known Russian experts, their soil, ice, para-pragithask plants and sometimes frozen body, which is 67 percent of the Surface of Russia's earth. The permaforest also expanded under the Arctic Sea in some place.

Chowalan, who graduated from the Department of Permafrost at Moscow State University, one of the few universities that is special.
From this ice box of the Arctic, bits or even whole frozen mothers, the custorian bells, the hair-stalking, the paragithasc horses, wolves and other ancient animals washed by the river bank. But Mr. Chowalan said he found no animal parts in the frozen soil. The explosion was thrown out.
Always frozen soil shards are usually some hundreds of yards, but they go down about a mile in some places in Siberia. Every summer, a part near the surface, known as active layer, is the tahos.
With hot summers, the active curtain is strong, potentially melting and the snow on gas deposits is weak.
"Because of the gas explosion, Chowalan said their current pressure was partially developed as organic components of permafrest, decades or hundreds of thousands of years ago," he said.
Another possibility is that methane is trapped in the deep layers of permaprost in a crystal, known as methane hydrate, gas in its recurrent state, possibly due to the effects of global warming. In this theory, gas is blown up by increasing pressure rather than throwing at the surface.
"It's like a bottle of champagne," Mr. Chowlan said.
Among the most recent, the 17th site at the Yamal Peninsula, was one of the more dramatic.
A pole deer had a header that was close enough to hear the explosion, but it was painful. The Russian scientific expedition came about a month after the helicopter arrived in August. The thread was at least 100 feet.

"While the Russian government is encouraging a low oil, natural gas and mining in the far north, there is still a high risk of an explosion," Mr. Chowlin said.
Mr. Chowalan, but Soviet and later Russian scientists did not document any examples in the first years, along with stories of such eruptions before 2014, said the header communities of the Pole deer. They have had rare incidents until recently. Global warming is faster Than the rest of the Earth's Arctic heat.
"The permaforst is not really very stable, and it never was," Mr. Chowalan said.
Within a year or two, craters are filled with water and are not more susceptible to small lakes.
