【摘要】 该文基于1950年以来新疆周边强震与境内中强地震活动的统计分析结果,解算了1976—2007年新疆周边强震活跃、境内相对平静时段,周边3组强震产生的库仑应力变化,并结合其后3年新疆地区中强地震活动特征,分析探讨了周边强震活动对境内地震活动的影响作用。结果表明,新疆周边这3组强震活动对新疆境内具有一定程度的减震作用。更多还原

【Abstract】 Based on the statistical results of the relations between strong earthquake surrounding Xinjiang and moderate-strong earthquake within Xinjiang from 1950,this paper calculates Coulomb failure stress changes of three groups of strong earthquakes surrounding Xinjiang during the active phase outside Xinjiang and the quiet phase inside Xinjiang from 1976 to 2007.Combining Xinjiang moderate-strong earthquake activity 3 years after these strong earthquakes,we analyze and discuss the influence of strong earthquakes surrounding Xinjiang on seismic activities within Xinjiang.The results show that the three groups of strong earthquake activities surrounding Xinjiang mitigate to a certain extent the seismic hazard in Xinjiang.更多还原
