摘　　要：对辽宁灯塔地震序列中的事件进行重新定位,最终得到了研究地区较精细的震中分布图像和有所收敛的震源深度剖面图像以及小震精确定位结果,结果显示辽宁灯塔震群大致呈北南向线性分布,初步推断该地区存在一条隐性北西向地震条带。We relocated sequence of Dengta Ms5.1 earthquake. We finally get the finer iomage of the earthquake distribution and the profile section of the convergen focal depth. The results show- that Liaoning Dengta earthquake swarm roughly north-south direction linear distribution,we concluded that the presence of a recessive north-west earthquake belt in the area.
