| 摘 要： | 位于福建省闽江中游的水口水库，自１９９３年３月蓄水以来，诱发了一系列水库地震。研究表明，这些地震具有国外一般水库地震的共同特征；库区为少震弱震区，地质构造并存在活断层；震源浅，震不集中；地震与水位变化相关性好等。此外，还具有ｂ值偏低，水位或降引发地震特别敏感等个别特怀。

| Abstract: | Earthquakes of Shuikou reservoir located at middle of Minjing River have been induced since the reservoir impounded in March, 1993. After studying up, it is indicated that these earthquakes have common features as well as general reservoir earthquakes at home and abroad, that is, the reservoir area is a region where the number of earthquakes is less and magnitude lower; the geologic structure complex and the active fault in existence; the seismic sources shallower; the epicentral locations concentrative and the correlation between earthquake and water level good. Mire than that, the b value of the earthquakes is lower and those usually were induced just as the water level changes sharp. |
