【Abstract】 The temporal distribution of induced earthquake following the filling of large reservoirs shows two types of response, rapid response and delay response.Based on analysis on the hydrogeologic condition of the seismicitic region,it is proposed that hydrogeological condition is the dominant factor that controls reservoir induced condition response with time.The rapid response is dominated by undrained or drained effect.The delay response is dominated by the diffusion of pressure from the reservoir to hypocentral depths.It is pointed out that the investigation of hydrogeological condition is the crucial problem in predicting reservoir induced earthquake.更多还原
