The study of the Earth's degassing processes is one of the main areas of research at the OGRI RAS. The authors created the geoinformation system "The Arctic and World Ocean" (GIS "AMO") with a huge amount of constantly updated geospatial data, giving possibilities for a comprehensive analysis of various natural and man-made phenomena directly or indirectly related to the degassing of the Earth. In the Arctic, a large amount of expeditionary works have been carried out with a wide range of geological and geophysical methods, which are analyzed in conjunction with RS data from space. This made it possible to obtain fundamentally new data on the gas-dynamic mechanisms of dangerous processes in the permafrost, including catastrophic blowouts and gas explosions with the formation of giant craters and mud volcanic eruptions. In total, about 18.5 thousand potentially dangerous objects were identified, which allows identifying the most dangerous zones in the terms of gas explosion in the north of the Western Siberia. In the Arctic, Caspian and other regions of the World, using remote sensing, the causes and consequences of technogenic degassing of the subsoil at a number of emergency oil and gas exploration wells with catastrophic consequences were investigated.

Keywords: Earth degassing, gas blowouts and explosions, mud volcanoes, gas seeps, remote sensing (RS), unmanned aerial vehicles (UAVs)
