Environmental disaster of gas hydrate: its relationship with submarine geology hazard, climate hazard and biology hazard

PENG Xiaotong1, ZHOU Huaiyang 1, CHEN Guangqian1, YE Ying2(1. Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640 ,China; 2. Department of Earth Science, Zhejiang University, Hangzhou 310027, China)  
This paper discussed the relationship of gas hydrate to submarine land slide, global warming and benthos extinction. The decomposition of gas hydrate in submarine decreased sediment strength and lead to excess pore pressure, which triggered submarine land slide. Gas hydrate and global warming could interact. Methane released from gas hydrate could provoke a global warming of 4 to 8 ℃ and the result of increasing temperature might neutralize the trend of global cooling or enhance the trend of global warming. The release of methane from gas hydrate led to the mass extinction of benthos, especially single cell fauna. Therefore, when we draw a plan to exploit gas hydrate resource, we must have consciousness and take technology measures to prevent or decrease various environment hazards triggered by gas hydrate exploitation. 
