Yushu earthquake 2010 ruptured the northwestern segment of the Ganzi-Yushu Fault in Qinghai, China. In this paper, the authors decompose the remaining GPS station velocities into strike-parallel and strike-normal components and examine the data along profiles across corresponding fault segments. The slip rates of the Fenghuoshan, Ganzi-Yushu, and northwestern segment of the Xianshuihe Faults are estimated as (6.1±1.9), (6.6±1.5), and (10.2±0.7) mm/a, respectively. These results agree with geological estimates of the fault slip rates, which show progressive increase from northwest to southeast across segments of the Ganzi-Yushu-Xianshuihe Fault zone, implying variation in transferring and absorbing patterns of deformation in different regions in and around the Tibetan Plateau.
