Natural gas hydrates in sediments are widely distributed in offshore continental margins and in polar regions. The amount of methane contained in gas hydrates is currently estimated to be between 10 and 10 m (Kvenvolden, 2000), considered an important natural resource in the future. Natural gas hydrates are also believed to be a factor in global climate changes (Haq, 2000) and submarine geologic hazards (Paull et al, 2000b).

The physical defects have existed widely in the natural rock, such as fracture, joint and fault and other discontinuous structural plane. The physical and mechanical characteristics of the rock have been influenced seriously by the structural plane, and also the seepage and thermodynamic features and other characteristics have been determined mostly according to the structural plane. It involves mine excavation, environment protection, water conservancy construction, radioactive waste disposal and reservoir induced geologic hazard etc.

Geological hazards vary in their nature and can be complex. One type of hazard, for example, an earthquake, can be responsible for the generation of others such as liquefaction of sandy or silty soils, landslides or tsunamis. Certain hazards such as earthquakes and landslides are rapid onset hazards and so give rise to sudden impacts. Others such as soil erosion and subsidence due to the abstraction of groundwater may take place gradually over an appreciable period of time. Furthermore, the effects of natural geohazards may be difficult to separate from those attributable to human influence. In fact, modification of nature by humans often increases the frequency and severity of natural geohazards, and, at the same time, these increase the threats to human occupancy.
