Abstract:: We discussed the characteristics of crustal deformation before and after the M_S6.8 BaChu-JiaShi earthquake,using multiple mobile GPS observation results and continuous observation results in WuShi、Taxkorgan GPS stations.We believe that each point near the epicenter moves to the NNW or NNE direction with the velocity of 15-20mm before the earthquake,which engendering high shear strain concentration area in the epicenter and adjacent area.However,the moving velocity of each point near the epicenter decrease to several millimeters after the earthquake and high shear strain concentration area disappears.At the same time,the time series of Wushi、Taxkorgan GPS continuous observation station appear wide-range sudden jump 2-3 months before the earthquake.
