Abstract：In this paper,the waveforms of 1272 earthquake events recorded by nine stations are selected in the western section of the Bolokenu-Aqikekuduke fault around 30 km during 2010-2015.Using cross-correlation analysis of waveforms,we identify 65 groups of repeating earthquakes.The results show that the repeating earthquakes make up 18.2％ of total events.Furthermore,we obtain the average slip rate about 0.99 mm/a at the Alashankou-Jinghe section,1.35 mm/a at the Jinghe-Xinyuan section,1.36 mm/a at the Usu-Shichang section,and 2.03 mm/a at the Balguntay-Wushicheng section,which is consistent with GPS observations.The maximum deep slip rate appears at the depth ranging from 2 km to 10 km,and the Balguntay-Wushicheng section reaches a maximum of 8.6 mm/a at the depth of 8 km.
