| 摘 要： | 计算2016年3月12日运城盐湖ML 4.8地震序列谱振幅相关系数，并与2006年代县震群相关系数进行对比分析。结果显示，2016年运城盐湖序列与2006年代县震群谱振幅相关系数总体呈下降趋势，但存在起伏变化，在转折上升过程中发生最大余震或震群的主震；2个地震序列的相关系数平均值均不高，可能是因为震源机制一致性较弱，区域应力水平较低。

| Abstract: | In the paper, the correlation coefficient of spectral amplitude of Yanhu ML 4.8 earthquake sequence in Yuncheng on March12, 2016 is analyzed and compared with the correlation coeffcient of Daixian earthquake swarm in 2006. The results show that the correlation coeffcient of spectral amplitude of Yuncheng Yanhu earthquake sequence in 2016 and Daixian earthquake swarm in 2006 both appear downward trends, existing up and down change, and the largest aftershocks or the mainshock of earthquake swarm occurs in the rising process of correlation coefficient. However, the correlation coefficient of spectral amplitude of two sequence are both not high, probably implying the weaker consistency of focal mechanism and the lower regional stress. |
