| 摘 要： | 本文结合编制 1：100 万辽宁省地震构造图,分析了辽宁省近 20 年来地震构造环境相关研究成果,确定辽宁地区共有第四纪以来活动断裂 29 条：全新世断裂 1 条;晚更新世断裂 5 条;早、中更新世断裂 23 条。其中北东向晚更新世活动断裂和北西向全新世活动断裂为辽宁地区的主要控震、发震构造。北东向晚更新世活动断裂与北西向断裂交汇部位、海城河隐伏断裂的端点部位和鸭绿江断裂南西端黄海海域是未来发生中强地震的主要部位。本研究可为深入研究辽宁地区地震构造条件、编制第五代全国地震区划图提供基础资料。

| Abstract: | Based on 1:1000000 Liaoning Seismotectonic Map, there are 29 faults that are active since Quaterary period in Liaoning Province. Among those one fault is active in Holocene, 5 are active in late Pleistocene fault, and 23 are active in early and middle Pleistocene. The major seismogenic structures in Liaoning Province are controlled by NE trending Q3 fault and NW trending Q4 fault. The intersection of NE trending Q2 fault and NW trending Q2 fault, the end positions of Haicheng river fault and southeast Yalujian fault in the Yellow Sea are the potential areas of moderate to strong earthquakes in the future. |
