摘要
以"霍山震情窗"的地震质为背景,讨论安徽省大别山地区"4大水库"的水位变化,引起的水库诱发地震,对"霍山震情窗"中提取更多前兆信息的影响。在科学地排除水库地震活动"穴"对"霍山震情窗"影响的同时,用地震活动窗的思想,客观反映孕震区附近的构造应力场信息,在华东及安徽省附近中强地震前后应力状态的差异性。
Taking the seismic geologic condition of ＂Huoshan seismic window＂ as the background, we discussed the influence of reservoir earthquakes caused by the water level variation of the ＂four greatest reservoirs＂ in Dabieshan area on the extraction of precursor information from the ＂Huoshan seismic window＂. After expelling the influence of the reservoir earthquake activity ＂cave＂ on ＂Huoshan seismic window＂ scientifically, the information of tectonic stress field in nearby seismogenie area and the contrast of strain status before and after moderately strong earthquakes near the Anhui, as well as in East China are reflected objectively.
