| 摘 要： | 大化水库自1983年蓄水后出现频繁的微弱地震,延续时间达7年,最大震为Ms1.7级,地震系列属震群型,初步判断属水库诱发地震。由于库区有活动断层且岩溶发育,地震诱发机制可能为断层孔隙水压力效应或岩液塌陷。从地震发展趋势分析,目前已处于衰减程过,预测今后不会有强震发生。

| Abstract: | Since the reservoir filling in 1982, weak earthquakes occurred frequently in Dahua Reservoir, which lasted for as long as seven years, the largest magnitude is Ms=1.7 and all of them belong to the type of earthquake swarms. The author judges that they are reservoir induced earth-quake.As there are active faults in the reservoir area and the karst develops very well, the mechanism of earthquake inducement may be caused by pore water pressure or karst subsidence. By analysing the developing tendency of earthquake, they are in the process of attenuation at the present time and it forcasts that strong earthquakes may not occur in the future. |
