【摘要】 水口水库建成蓄水后诱发了频繁的地震活动 ,至今延续时间已超过 10年 ,目前还在继续活动。其间共诱发地震 12 0 0余次 ,其中最大震级是 1996年 4月 2 1日发生的ML4 .1地震。根据诱发地震序列资料 ,对水口水库诱发地震的区域地质构造背景、时空特征、地震序列性质、地震活动趋势以及可能诱发的最大震级进行了综合研究更多还原

【Abstract】 After the Shuikou reservoir being built and impoundment, it has been inducing frequent seismic activity for ten years. Up to now, more than 1 200 earthquakes are recorded, among them, the largest one is %M%-L4.1 in April,1996. In this paper, according to induced seismic sequence, an integrated study and analysis on the regional geologic structure setting, the temporal and spacial characteristics of seismicity, the characteristics of seismic sequence, the active tendency and the maximum magnitude of induced earthquake in the Shuikou reservoir was carried out.更多还原
