摘      要：In this research work,we present the evolution of Coulomb failure stress(CFS)in the Sulaiman Lobe and its implications for seismic hazard *** Chaman transform fault,~1,000 km long,is the major active fault that marks the western boundary between Pakistan and Afghanistan on the Indian *** date,few studies have been conducted to unveil the interactions among earthquakes and the implications of these interactions for seismic hazard assessment in the *** thoroughly investigated the published and online catalog to construct a sequence of major earthquakes that occurred in this region during the *** final earthquake sequence was composed of 15 earthquakes of M_(w)≥6.0,beginning with the 1888 *** used the stress-triggering theory to numerically simulate the evolution of CFS caused by these *** numerical results revealed that 8 out of 15earthquakes were triggered by the preceding *** earthquakes in 1908,1910,1935,1966,and 1997 were rather independent earthquakes in this *** the epicenters of the 1975a and 1975b earthquakes were in the stress shadow zone,the partial rupture segments of both these earthquakes were in high-CFS *** CFS induced by the 1935 earthquake was notable,as it later triggered the 2008 ***,our results revealed that the northern segment of the Chaman Fault,the southern segment of the Ghazaband Fault,and the northwestern segment of the Urghargai Fault demonstrated a high change in CFS that could trigger seismicity in these *** necessary arrangements must therefore be made to mitigate any possible seismic hazards in the region.
