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.
