Four inversion results of the rupture process of 14 April 2010 oft-com:office:smarttags" />Yushu, Qinghai, earthquake, obtained by inverting the broadband seismic data of Global Seismographic Network (GSN) based on the inversion method of earthquake rupture process, was compared and discussed. It is found that the Yushu earthquake has several basic characteristics as follows: 1) there exist two principal sub-events which correspond to two slip-concentrated patches locating near the hypocenter and to the southeast of the epicenter; 2) the peak slip and peak slip-rate are about 2.1 m and 1.1 m/s, respectively, indicating that the Yushu earthquake is an event with large slip-rate on the fault plane; and 3) overall the Yushu earthquake is a unilateral rupture event with the rupture mainly propagating southeastward.oft-com:office:office" />
