Russian scientists have begun studying a new gas release funnel that was discovered in the tundra of the Yamalo-Nenets Autonomous district. The Russian center for Arctic development claims that the funnel is in perfect condition, which will allow it to be studied in detail.
Several craters have been found on the territory of the Autonomous district since 2014. The depth of the most famous - in the area of the Bovanenkovskoye field-is at least 35 meters, the diameter is about 40 meters, at the moment they are completely submerged. The reason for the formation of craters is the release of gas from the ground. Another sinkhole was formed on June 28, 2017, 34 kilometers from the village of Seyakha, its depth at the narrowest point is more than 50 meters. The new funnel is the 17th such find since 2014.
"In the permafrost, a gas-saturated cavity is formed, an empty space filled with gas with high pressure. When the pressure of the gas mixture exceeds 12 atmospheres, a stream of great force, accompanied by a loud sound, breaks out, tearing the earth's permafrost surface, scattering blocks of ice and soil for hundreds of meters, forming a cylindrical funnel, up to 50 meters deep with perfectly round shapes," the center said.
