摘要
以山西测震台网2016-2018年的地震观测报告为基础,分别对震中分布、主要震相、震源深度和震级等参数进行统计分析,认为山西测震台网震相分析质量较高,无偏差较大的现象发生。通过线性拟合的方法得出山西地区主要震相的平均传播速度,验证了该地区地壳速度模型的正确性。
Based on the 2016-2018 earthquake observation reports of Shanxi seismic network,this paper carries out statistical analysis on the parameters such as epicenter distribution,main seismic phases,focal depth and magnitude.The results show that the quality of phase analysis of Shanxi seismic network is high,and there is no phenomenon of large deviation.The average propagation velocity of main seismic phases in Shanxi area is obtained by linear fitting method,which verifies the correctness of the crustal velocity model in this area.
