Abstract：In Badong alongshore zone of the Three Gorges reservoir and its adjacent regions, the changes of seismicity and strength are caused by the impoundment of the Three Gorges reservoir. According to the basic seismic data and characteristic of wave, the earthquakes in this area can be distinguished into tectonic earthquake and atectonic earthquake. The latter includes karst collapse, mining collapse and hill collapse and all of them are caused by water action of reservoir i.e. they are reservoirinduced earthquake.
