(a) Distribution of aftershocks (circles) determined by the China Earthquake Networks Center. The light blue and white stars indicate the hypocenters determined by the USGS and the China Earthquake Networks Center, respectively. The solid black line indicates the fault model of the mainshock. The light-blue and white lines indicate the Manyi-Yushu-Xianshuihe fault and the observed surface rupture trace shown in Chen et al. (2010) and Lin et al. (2011). The purple square indicates the county seat of Yushu. (b) The deformation field caused by the 2010 Yushu earthquake. The flight and line-of sight directions are also shown in the panel. The black line and star indicate the fault model and hypocenter used in this study. (c) Results of the W-phase (left) and P-wave (right) centroid location grid searches. Inverted grids are colored by their misfit percentage relative to the minimum RMS value. The best-fitting solution is shown with a star. Red, light-blue, and white lines indicate the fault model, the Manyi-Yushu-Xianshuihe fault, and the surface rupture trace, respectively. (d) Stations observing the teleseismic seismograms used in this study.
