Fundamental aspects of the catastrophic gas blowout genesis and the formation of giant craters in the Arctic

Abstract
The article considers the fundamental aspects of powerful explosive degassing of the Earth in the north of Western Siberia (mainly Yamal). The author presents the results of a comprehensive analysis and compilation of a large volume of factual materials obtained during field studies of a number of catastrophic gas blowout objects in 2014—2020. The author outlines that most of the craters found in Yamal are confined to the zone of anomalous heat flow in the area of the Bovanenkovskoye field. The researcher substantiates the process formation model of gas-saturated cavities in the massifs of ground ice, heaving mounds, blowouts and self-ignition of gas with the formation of giant craters and formulates the main features of powerful explosive degassing in the Arctic.
