摘要:
通过国内许多学者研究丽江M7.0地震震源过程及云南地区地壳结构的结果,运用离散波数法,计算了丽江地震产生的动态库仑破裂应力变化,并研究了其与后续余震活动的关系。结果表明,丽江主震产生的动态库仑破裂应力场瞬态的正区与稳态的正区对余震的发生促进作用十分明显。
Abstract:
Based on the research on the focal process of the Lijiang M7.0 earthquake and on the crustal structure of Yunnan,we use discrete wavenumber method to calculate the dynamic Coulomb rupture stress changes caused by the Lijiang earthquake and study its relationship with the aftershocks.The results show that the positive peak value regions of dynamic and static Coulomb rupture stress changes caused by the Lijiang mainshock are helpful for the occurrence of the aftershocks.
