Abstract
This paper reports on the heaviest submarine fluxes of natural gas bubbles (flares) that have occurred in the Sea of Okhotsk, the Laptev Sea, and Lake Baikal. It has been concluded that there is a “gas-geochemical response” of geodynamic and seismotectonic processes in the interaction of lithospheric plates. Using the example of one of the lineaments of Eastern Asia, we have shown that lineament geotectonic structures, which compose the regmatic net of the Earth, control the formation and activity of the biggest centers of methane emission, which are indicators of tectonospheric activity and hydrocarbon accumulation. Changes in the activity of these centers are informative signals of seismic fluctuations. It is concluded that Russian studies play a leading role in gas hydrate forecasts in the seas of the Eastern Arctic.
