Abstract
The Jianhe MS 5.5 earthquake has relatively serious threat to people's lives and property in earthquake region, and has certain influence to “the safe island of earthquake” southeast Gizhou. This paper briefly describes the tectonic background of Daxinan-taihang-wuling gravity gradient zone and its faults, and analyzes of the cause of the Jianhe MS 5.5 earthquake. The results show that the Tudong fault cutting through the reservoir joins the Jianhe (gedong) -taijiang fault in deep epicenter, which results in the concentration of local tectonic stress and earthquake preparation; under the influence of water percolation of fault and function of Sanbanxi reservoir's load, stress is unbalanced and earthquake is triggered. By the adjustment of reservoir, the greater earthquake may be prevented and avoided.关键词
