【摘要】 根据地震动态触发理论,计算了2000年苏门答腊MS8.0,地震在缅甸MS6.5地震破裂面上产生的动态库仑应力:正峰值为1.357 5 MPa,负峰值为-1.113 5 MPa。峰值大于地震触发阈值0.01 MPa,苏门答腊地震的发生对缅甸地震具有一定的触发作用。在计算过程中发现,主震基本参数、传播过程中介质参数和被触发地震断层参数的准确性对计算结果有较大影响。更多还原

【Abstract】 According to the seismic dynamic triggering theory,we calculate the dynamic coulomb stress changes in rapture planes of Burma 6.5 earthquake after Sumatra 8.0 earthquake: the positive and negative peak values of dynamic stress are 1.357 5 MPa and-1.113 5 MPa,respectively.Sumatra earthquake triggered the Myanmar earthquake to certain degree,because the peak change is greater than the earthquake triggering thre-shold 0.01 MPa.In the calculation process,we found that the basic parameters of the main shock,the medium parameters in transportation process and the fault parameters of triggered earthquake have a significant impact on the calculation results.更多还原
