ABSTRACT: Methane clathrate hydrate (MH) bearing sediments related Geomechanics issues are summarized. Mechanical properties of MH bearing sediments highly depend on the saturation of MH, pressure and temperature and structure of it in pore spaces. Such mechanical properties influence various scales of geological formation stabilities. Because the stability of MH is a function of temperature and pressure, the mechanical behaviour of the material is coupling phenomena of mechanics to fluid dynamics and heat transfer phenomena. Also the host sediments are relatively shallow unconsolidated or weakly consolidated sand, silt or clay, and there behaviour itself is complex. To understand the physical and mechanical processes, all of the elements stated here should be taken into account. 1
