POSSIBLE SEISMOGENIC TRIGGER MECHANISM OF ABRUPT ACTIVATION OF METHANE EMISSION AND CLIMATE WARMING IN THE ARCTIC

The author proposes a seismogenic trigger mechanism to explain the abrupt activation of methane emission and climate warming phases in the Arctic as a result of strong mechanical disturbances in the marginal region of the Arctic lithosphere, caused by the great earthquakes in the Aleutian subduction zone, the transfer of these disturbances to the Arctic shelf and adjacent regions, and the trigger effect of the methane release from permafrost sedimentary rocks and metastable gas hydrates with subsequent emissions of greenhouse gas into the atmosphere.
