| Abstract: | In this paper, the characteristics of three earthquake sequences with ML ≥4. 0 main events occurred during the latest 2 years have been compared with the focal mechanism and depth of the major earthquakes as well as the parameters of sequences. Further, we have preliminarily analyzed the regional seismic hazard based on the seismicity feature, characteristics of the sequences, and seismic apparent stress result. |
