Scientists have discovered two peninsulas of Yamal-Nenets Autonomous district hills, which may be the precursors of giant craters resulting from ejection of gas out of the ground, reported the press service of the Tyumen industrial University.

In 2014, in the district of Bovanenkovo Deposit on the Yamal Peninsula was discovered two funnels, which, as expected, was the result of gas emissions, and then filled with water, becoming a lake. The diameter of one of them on the outer edge at the time was at least 60 meters and a depth of 200 metres. At the same time, according to scientists, in recent years the crater has increased in size, and the water is characterized by very high turbidity and different from other nearby lakes.

«Tyumen scientists on two peninsulas of the Arctic region — the Yamal and Gydan — exploring the particular mounds of swelling that preceded an explosion and the emergence of the famous Yamal funnels. But the blowout is possible to predict», — stated in the message of the University.

According to associate Professor of the Department of Earth’s cryosphere, Tyumen industrial University Anatoly Gubankova such hillocks «Mature» for about three years.

«Today, sold less than a dozen craters. For the settlements of the danger they represent… This is a very dangerous process, but predictable. In the fields in the monitoring services are experienced experts, so no reason to panic there. Mature mound height of two to three meters, not to notice this before it will be impossible. The only one where it is difficult to predict the explosion is in rivers and lakes», — quotes the press service of the University words Gubankova.

In this case, as in Tyumen scientists believe, a real risk of new explosions is available only on deposits of Bovanenkovskoye group.

Earlier in the Earth cryosphere Institute in Tyumen scientific center Siberian branch of the Academy of Sciences, which also study these natural processes on the Yamal Peninsula, told RIA Novosti that in 2018, a group of scientists planned three expeditions in the YNAO, including in the areas of the craters and gas emissions. Researchers plan to draw up a forecast map. They believe that this natural phenomenon is due to warming. In particular, according to them, in the past year, a number of gas emissions on the Yamal Peninsula occurred after the extremely warm summer of 2016.
