| 摘 要： | 大化水库自1982年蓄水后发生频繁的微弱地震,主要有6个小震群,延续时间长达7年,但由于震级很小(最大震级Ms1.7),对电站运行无影响。从地震发展趋势分析,目前已处于衰减过程中,但微震仍可能继续一段时间,故地震监测工作应继续进行。

| Abstract: | Since the water are stored in the Dahua Reservoir in 1982, the weak earthquakes occurred frequently,which belong to the small earthquake swarm and lasted for as long as seven years, and among them the largest magnitude is Ms=1.7. The author judges that they are the reservoir induced earthquake. As there are the active faults and the well developing karsts in the reservoir area, the mechanism of earthquake inducement may be caused by the porewater pressure or karst subsidence. By analysing the developing tendency of earthquakes, the seismic activity is now in the process of attenuation, and the strong earthquakes could not occur in reservoir region in the future. |
