| 摘 要： | 本文在分析辽宁岫岩地区地质构造、新构造运动、地震活动、地球物理场及深部构造等资料的基础上,对岫岩地区的地震地质背景和地震危险性作了分析和研究。认为在岫岩西北部的偏岭地区属海城地震的余震区,地震活动受北西向海城河断裂的控制,这里具备发生5-6级地震的构造条件。其它地区属中、小地震活动区。在有旋扭构造发育的地区,当外区有强震发生时有可能出现震害加重的现象。

| Abstract: | Base on the data of geological structure,neotectonic,seismicity,geophysical field,deep structure,etc.This paper presents an analysis of seismogeological background and earthquake risk in the Xiuyan county,Liaoning Province some research results can be triefly described as follow:(1)The Pianling area situated in the north-west part of Xiuyan county is a seismicity one with seismogenic structure caused the earthquakes of magnitude 5-6.(2)Other area of the Xiuyan county is a weak seismicity one only caused small-middle earthquakes. |
