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-west and north-west directions. The revised hypocenter locations showed some relations with the known major active faults.
