摘要
辽宁半岛及两侧海域地震活动频繁，地震活动在空间上显示有条带状，网络状和团块状等分布特征，本文通过地震活动与深部构造、活动构造关系的分析认为，莫氏面的形态、深断裂的发育特征和活动断裂的特殊部位等对地震分布起了控制作用。
Liaodong Peninsula and its surrounding sea area are one of the places where the seismicity is frequent.The spatial distribution of seismic activity may emerge from some patterns with stripe shape,network shape and cluster shape etc.This paper presents an analysis of the relation between the deep tectonic,active tectonic and the seismicity.The results show that the shape of Moho discontinuity,the development of deep faults and the special sites of active faults play a controlling role in the seismic distribution,therefore,a number of distribution patterns of seismic activity were formed in the research region.
