  • 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.
