| Abstract: | The water level variation of the Yudong reservoir in Zhaotong, Yunnan, and the seismicity and tectonic stress field in the reservoir and nearby before and after the water storage have been analyzed. The results show that the pattern, strength and frequency of the seismic activity do not change obviously before and after the water storage. Both water storage and level variation have not influenced the tectonic stress field in the study area obviously. |
