摘　　要：利用台阵分析软件、"十五项目"地震分析软件,结合新疆强震台网数据与新疆地震台网数据的交切法和俄罗斯科学院提供的比什凯克科学站地震数据、新疆强震台网数据与新疆地震台网数据的交切法,对2008年10月5日乌恰6.8级地震进行了重新定位。分别采用4种方法进行定位,对定位结果进行比较与讨论。分析后判定,2008年10月5日乌恰6.8级地震类型为主震余震型。并利用新疆地震台网清晰震相对6.3级余震也进行了定位。Wuqia earthquake with Ms6.8 on Oct. 5 in 2008 is mainshock-aftershock type. The characteristics of aftershocks are flexuous attenuating. With the help of SWA, the fifteen project seismic analysis software, we relocated Wuqia Ms6.8 earthquake, using intersection of seismic network and strong motion network data in Xinjiang, seismic network and strong motion network data in Xinjiang and the data provided by Bishkek＇s scientific stations . After comparing and corresponding review the results of the above four methods, we gave the seismic vertical location of Wuqia earthquake with Ms6.8,using the same methods we gave the seismic vertical location of its aftershock with Ms6.3.
