| 摘 要： | 基于云南数字地震台网记录,计算了印尼大震、昆仑山口西大震和古吉拉特邦大震的地震波在云南地区产生的远场动态库仑破裂应力变化,研究了大震产生的动态库仑破裂应力变化对云南地震活动的远场动态应力触发作用及其特征。结果显示,印尼大震产生的库仑破裂应力对云南地震活动有明显的触发作用,昆仑山口西大震产生的库仑破裂应力对云南地震活动有触发作用,但不显著,古吉拉特邦大震在云南地区产生的库仑破裂应力没有触发作用。最后分析和探讨了这3次大震触发作用差异的原因。 |

| 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 MS8.7 Indonesia earthquake,MS8.1 Kunlun earthquake and MS7.8 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 failu... |
