Seismogenic-triggered Mechanism of Activization of Methane Emission in the Arctic as Possible Factor of Climate Warming
A seismogenic-triggered mechanism is proposed to explain the abrupt activization 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. Those disturbances might have been caused by great earthquakes in the Aleutian subduction zone, and slowly propagated across the Arctic shelf and adjacent regions, triggering the methane release from permafrost and metastable gas hydrates, followed by greenhouse gas emissions into the atmosphere.
