Abstract
Sudden natural gas blowouts from within the permafrost sections in West and East Siberia and some results of permafrost core samples study are present ed. Topics covered include gas geochemistry, blowout intensity (gas flow ra te), depth interval and permafrost rock peculiarities in places of these ga s releases. Although microbial gas is widespread within permafrost, thermog enic gas can also occasionally migrate from deep gas reservoirs along fault s, or be present locally in areas of gas reservoirs within the permafrost s ection. Gas can be preserved within permafrost in a free state as well as i n hydrate form throughout the permafrost zone and be a potential threat to climate in the course of global warming.
