%X In this paper, we relocated earthquakes occurred around Longtan reservoir from 2006 to 2007 by using hypoDD relocation method and waveform cross-correlation technique, analyzed its seismic activity. Relocation results by applying the waveform cross-correlation technique and hypoDD method demonstrates that the earthquake location quality are obviously enhanced. Analysis of the characteristics of seismicity around Longtan reservoir proved that there is a tight correlation between the seismic activity around Longtan reservoir and the process of reservoir recharge. Earthquakes clustered around Longtan reservoir region and performed different response corresponding to water level change respectively, indicating that there may exist local differences of lithological characteristic, penetrative condition, geological structure, as well as stress field condition around the Longtan reservoir.
