Study of the Induced Earthquake of Kongliang Reservoir

The deep geological structure,geophysical and seismic record,and karst hydrological characteristics of Kongliang reservoir are discussed in the paper.The stress concentration of the compression nappe structure in the upper crust is the dynamic source of the natural earthquake.The nappe structure also controls the reservoir induced earthquake's distribution and strength.Synthesizing various estimation method results and by the help of seismo-geological condition analysis,we get the result that the magnitude of the biggest earthquake in Kongliang reservoir is about 4,the intensity is Ⅵ.
