According to the British newspaper The Independent, the large crater was initially discovered in July by a television crew flying over the area returning from working on the phenomenon.
A team of scientists from the Russian Center for the Development of Arctic Lands has already announced that they are studying the “big” crater, which is the result of a gas eruption that occurs in the middle of the Yamal tundra, in the northwest from Siberia.
Scientists believe that the formation of these craters is related to the accumulation and subsequent explosion of methane gas, which may be a consequence of the high temperatures in the Siberian tundra, but they admit that much remains to be discovered.
“For now, there is no single accepted theory about the formation of this complex phenomenon. They may have developed over several years, but it is difficult to estimate. Since craters often appear in uninhabited and largely unspoiled areas of the Arctic, there is often no one to document them, “lead researcher Evgeny Chuvilin explained to CNN.
“Even today, craters are usually found by accident during helicopter, herder or hunter flights,” he said. The researchers explain that methane accumulates in a layer of soil that never freezes and acts as a “trap.” When the gas is released, it deforms the ice and soil, forming a “pile.” In the summer heat, these “hills” explode creating giant craters.
At the same time, the record temperatures recorded this summer in Siberia are causing an unprecedented expansion of the Batagaika Depression, known worldwide as the “door to the underworld.”
The Batagaika Crater in the eastern Siberian republic of Sakha was formed in the 1960s after the state ordered the clearing of the surrounding forest. The absence of the biosphere caused the earth to “sink.”
Currently the world’s largest depression, one kilometer wide and 100 meters deep, the crater continues to grow and expand due to global warming and the melting of the region’s permanently frozen soil.
