摘要

在分析3次千岛群岛大地震对应东北地区地震的基础上,讨论了在地质构造背景下千岛群岛大地震引起板块俯冲与我国东北地区地震的相关性。结果表明,千岛群岛发生7级以上地震对应东北地区地震有较强相关性;千岛群岛在大地震破裂过程中产生的俯冲作用自东向西对东北板块产生挤压作用,东北地震区相继发生了浅源地震;千岛群岛地区发生地震时,东北地震区地震活动明显提高。
At fi rst,the relationship between 3 large earthquakes in the Kuril Islands and the earthquakes in Northeast China are analyzed.Then,on the background of the geological structure, the relativity between plate subduction caused by Kuril Islands earthquakes and the earthquakes in Northeast China is discussed.The result shows that the earthquakes above magnitude 7 in Kuril Islands are closely related to the earthquakes occurred in Northeast China. The subduction caused in the rupture process of large Kuril Islands earthquake pushes the Northeast plate from east to west,and then shallow-focus earthquakes subsequently occur in northeast seismic zone.When earthquake occurs in Kuril Islands,seismic activity of northeast seismic zone is significantly increased.
