Study on the Triggering Effect of the October,2005 Pakistan Mw7.6 Earthquake on Its Aftershocks
摘要
Abstract
The influences upon aftershocks of Coulomb failure stress change (CFSC) generated by the main-shock of the October 8,2005,Pakistan earthquake are calculated and analyzed.The following factors are included in the calculation:(1) the difference between the pore fluid pressure and the medium elastic constant in the fault plane area and those of its surrounding medium;(2) the tectonic stress direction of the seismic source area;(3) the aftershock failure mechanism of aftershocks is calculated by stacking the tectonic stress with the stress change generated by the main-shock.Our study,which includes many factors,fits fairly well with the aftershock distribution.It indicates that most of the aftershocks were triggered by the Pakistan main-shock that occurred on October 8, 2005.关键词
