摘要

利用2008年以来辽宁地区流动重力网观测资料,探讨了该地区重力场时空演化特征与中小地震震中分布的关系,分析认为:(1)测区重力场出现高值异常现象,重力场异常时空动态变化与该区构造活动密切相关;(2)辽宁地区近年来所发生M3.0级以上中小地震震中分布多位于重力异常高值区。
Based on the mobile gravity data in Liaoning since 2008,the relationship between the spacetime evolution characteristics of gravitational field and moderate-small earthquakes epicenters distribution has been discussed.It is considered that the high value and the abnormal space-time evolution in gravity field are closely related with tectonic activities in this area.In addition,the epicenters of more than M3.0earthquakes in recent years mostly distributed in high value areas.
