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

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