Abstract:: The changes of far-field dynamic Coulomb failure stress produced by great earthquakes in Yunnan are calculated on the basis of seismic records from 26 digital seismic stations in Yunnan by using three great earthquakes as examples including M_S8.7 Indonesia earthquake,M_S8.1 Kunlun earthquake and M_S7.8 Gujarat earthquake in India.The far-field dynamic triggering effect of Coulomb stress changes on seismicity and their triggering characteristics are studied in Yunnan.Result shows that the dynamic Coulomb failure stress caused by the Indonesia earthquake have strong triggering effect on earthquake activity in Yunnan,the stress of Kunlun earthquake also have some triggering effect,but that of Gujarat earthquake don't have triggering effect.The physical mechanism of the different triggering effect among the three earthquakes are investigated and discussed.
