In 2015, the global earthquakes with Ms ≥7.0 occurred mainly in the west segment of the circum Pacific seismic belt and the Eurasian seismic belt. Features of global seismicity of Ms ≥ 7.0 in 2015 are as follows ：展开更多

This paper has studied the seismicity parameters of the earthquake sequences such as the b-value in the Pishan region and its vicinity. In addition,we also relocated the aftershocks of the Pishan M_S6. 5 earthquake using the seismic phase report by the double-difference method. The temporal and spatial variation characteristics of the Pishan earthquake sequence in the rupture zone are analyzed. The study is of great significance in the seismic hazard assessment in this region.展开更多
