Schematic evolution of retrogressive slope failure due to overpressured gas below the gas haydrate stability zone (GHSZ): a submarine slope with gas hydrate-bearing sediments  and overpressured gas (bright area) at the bottom of the GHSZ induces pipe generation into the GHSZ,  the conduit encounters a permeable layer; gas enters and leads to overpressure transfer from the bottom of the GHSZ to the shallow subsurface, and finally overpessured gas causes shear banding in the weak layer and generates retrogressive slope failure.
