英文摘要	The left-lateral strike-slip Xiaojiang fault system is a main boundary between the southeastern Tibetan Plateau and the South China Block, and accumulates several large (M>7) earthquakes in the past similar to 500 years and a dozen of moderate (5 7) earthquake ruptures occurred in the past similar to 500 years are simulated with split-node technique in seismogenic upper crust. We investigate the Coulomb failure stress changes mainly on vertical planes parallel to the different strands of the Xiaojiang fault system, and at the epicenters of large (M>7) earthquakes in the past similar to 500 years and of moderate (5 7) earthquakes that occurred in the past similar to 500 years both from their coseismic and postseismic effects, among which the postseismic effect results in the stressing rate being obviously accelerated near epicenters of the large (M > 7) earthquakes after their occurrence. Thus, the percentage of positive Coulomb failure stress changes of >0.01 MPa at the epicenters increases from similar to 37% to similar to 50% for the large (M>7) earthquakes, and from similar to 43% to similar to 64% for the moderate (5
