| 摘 要： | 分析中国东北地区深震 (mb≥ 6 .0 )及浅震 (MS≥ 5 .0 )的成组性活动特征 ,研究了深震“强震组”与浅震“强震组”的时、空相关性。着重探讨了西太平洋板块与欧亚板块碰撞带的地震分布特征及其与西太平洋俯冲带形态的关系 ,并着重分析了西太平洋板块对欧亚板块地震活动的影响。结果表明 :西太平洋板块俯冲倾角小的地区 ,板块碰撞带地震活动强烈 ,板块俯冲对欧亚大陆的影响也较强 ,俯冲带处于较强的挤压应力状态 ;西太平洋板块俯冲倾角大的地区 ,板块碰撞带地震活动较弱 ,板块俯冲对欧亚大陆的影响也较弱 ,深部俯冲带引张应力增强。分析认为 ,未来 10年中国东北地区将进入浅震“强震组”活动时段 ,期间可能发生MS≥ 5 .0地震 6次左右 ,应加强东北地区的地震监测预报工作

| Abstract: | Based on the analyses of grouped activities of deep-focus (m b≥6.0) and shallow-focus (M S≥5.0) earthquakes in Northeast China, the spatial and temporal correlation between the deep-focus "strong earthquake group" and shallow-focus "strong earthquake group" was studied. The study was focused mainly on the characteristics of earthquake distribution along the collision zone between the west Pacific plate and Eurasian plate, as well as its relation to the form of the west Pacific subduction zone.
