| 摘 要： | 丹江口水库二期蓄水后，根据2013～2015年地震台网监测成果分析，库区地震主要以微震、极微震为主，震中位置每年均呈团状或带状聚集在5个密集区，没有随库水位变化发生明显迁移现象。丹库区地震强度和频度高于汉库区，丹库区以水库地震居多，汉库区以水库地震及其他类型非构造地震居多。

| Abstract: | After the second phase water storage in the Danjiangkou reservoir, according to the monitoring results of seismic network from 2013 to 2015, reservoir earthquakes are mainly either microseismic or ultra-microseismic. The epicenter location cloddy or banded together in five concentration areas every year. There is no apparent migration phenomenon along with the change of reservoir water level. Earthquake intensity and frequency in Dan reservoir are higher than Han reservoir. Earthquakes in Dan reservoir are mainly reservoir-induced, while the Han reservoir earthquakes combine reservoir-induced earthquakes with other types of untectonic earthquake. |
