%X A part of the aftershocks of Yushu earthquake occurred from April 14 to December 31,2010,were relocated by means of the double difference algorithm.These following conclusions can be obtained from the results.The area changing of stress growth led to aftershocks distribution shifting over time.The aftershock distribution presents spatial inhomogeneity.On both sides of Longbao,the intensity,width and the focal depth of the aftershocks are different.The seismogenic fault of aftershocks of Yushu earthquakes is the northern branch of Garzê-Yushu fault zone,i.e.Yushu-Longbao fault,which dips to northeast with high-angle left-lateral strike-slip.To the northwest of Longbao town,the intensively distributed aftershock group is not only due to Yushu-Longbao fault zone,the more important seismogenesis is that the northwest "weak plane" is nearly vertical to the fault.
