通过长江三峡库首区沿江段、盐关和仙女山断裂带３个小孔径台网近３年的地震强化观测，发现该地区同时存在着天然地震和矿山地震。其中黄陵背斜轴部结晶花岗岩体内没有观测到极微震活动；西缘秭归香溪至龙马溪一带存在着百余次微震，最高震级为ＭＬ２．５级盐关地震，与这一带的矿山开采有关；东缘宜昌石门附近也分布有数次微震；在黄陵背斜外围区域分布着若干３～４级（ＭＬ）弱震。这些地震的发生基本上反映了该地区的弱活动构造格局。
Through the three years of intensive seismic observation of the three small aperture stations in the Yangtze River Three Gorges reservoir in the Yangtze River, Yanuan and Xiannushan fault zones, it is found that natural earthquakes and mine earthquakes exist simultaneously in this region. There is no microseismic activity observed in the crystalline granite of the axis of the anticline in the Huangling anticancer. There are over one hundred microseisms in the vicinity of the Xiangxi-Longmaxi belt in the west margin, the highest magnitude is the ML2.5-level salt-related earthquake, and the mining in this area There are also several microseisms around the Shimen near Yichang in the eastern margin; and some weak earthquakes of magnitude 3 to 4 (ML) are distributed in the periphery of the Huangling anticline. The occurrence of these earthquakes basically reflects the structure of weak activity in the area.
