Abstract
The release of methane deposits in the Arctic, which is bound in the form of gas hydrates, can accelerate global warming. The threat of increasing methane content in the atmosphere is associated with the decomposition of gas hydrates located in the sedimentary layer in a metastable state. The authors formulate destruction mechanisms that can affect the dissociation of natural gas hydrates and assess the risks of possible gas emissions during the advancement of slow tectonic waves. They have studied the instability of moving granules of the sedimentary strata and obtained the condition for the bifurcation of the micropolar continuum, which may be associated with the emission of methane from zones of accumulation of metastable relict gas hydrates.
