英文摘要	Using the broadband P wave records of the Global Digital Seismograph Network (GDSN) and the adaptive hybrid global search algorith, we investigate the rupture process of the 19 March, 1996 Artux, Xinjiang, earthquake(M-S = 6.9). Slip vectors, risetime and rupture time for a finite fault are obtained and their errors is estimated by introducing a random weight method. Aftershock data, field geology and seismic investigations are applied to constrain the fault plane. This event occurred in the west part of the Kalpin fault zone and is a unilateral-rupture thrust event with a small strike slip component. The fault plane has a stricke of 252 degrees and a dip of 30 degrees. The rupture duration is 15s and the focal depth is 13km. We conclude that the inferred slip distribution contains two major slip sources. A sub-event with a slip amplitude of 0.3m and a risetime of 0.8s is located at the hypocenter. The maximum slip amplitude of 1.0m is associated with a 3.5s risetime subevent located to the east of the first major slip source. The distance between the two major slip sources is about 25km, and corresponds with the 30km difference between the instrumental and macroseismic epicenters.
