【摘要】

：

利用濮阳周边数字地震台网近十年的震相观测报告数据及3级以上地震事件的波形记录,基于人工地震宽角反射/折射剖面的速度模型,采用Hypo2000地震定位法对研究区内1级以上287次地震事件进行绝对定位。同时,以Hypo2000绝对定位结果为初始位置,对濮城镇附近约25 km范围内的153个一级以上地震进行双差相对定位,获得更为准确的相对位置关系。定位研究结果表明:重新定位后研究区的小震震丛在震中和震源

应用综合震源机制解法对辽宁及邻区现今构造应力场的初步分析

根据辽宁测震台网最近10年记录到的6 245次天然地震,28 698个P波初动极性数据,在考虑不同震中距数据权重的同时给出辽宁及相邻地区0.25°×0.25°的精细构造应力场,并结合构造背景对反演结果进行分析。总体来看,反演得到的主压应力轴方位以NE、NEE向为主,倾伏角较小;主张应力轴方位以NW、NNW向为主,局部有近NS向分布,倾伏角近乎水平。该结果与之前学者的研究比较相近。大多数网格点的主张
