Seismic activity analysis of relocated earthquakes in southwest Tienshan region
西南天山地区的地震重定位与活动性分析

We presented the relocated hypocenter parameters for 522 events of 864 earthquakes which occurred in the southwest Tienshan region. The double-difference (DD) relocating method was utilized to produce the pronounced relative event locations through adopting both the absolute and relative P-wave arrival times. The resolution of the relocated earthquake hypocenters was significantly increased. After the relocation, those formerly randomly-distributed earthquakes were clustered and aligned tending to the east-...
