本文统计分析了湖北区域地震台网记录的近震资料,通过震级残差分析和最大震相平均衰减特性的估算,对现行测定M_L震级量规函数进行区域修正,得到新量规函数R_3(△),同时计算了该台网各台的台基校正值.在此基础上利用该台网又记录的近震资料进行验证,结果表明,应用R_3(△)和台基校正有助于提高该区域台网测定震级的一致性,使M_L震级误差从0.27下降至0.22左右.
This paper statistically analyzes the near-Earthquake data recorded by Hubei Seismological Network, and through the analysis of the magnitude residuals and the estimation of the average attenuation characteristics of the maximum phase, the existing measure M_L magnitude gauge functions are corrected by region, and the new gauge function R_3 (△) At the same time, the station-based correction value of each station in the network is calculated, and based on this, the near-field data recorded by the station network are used for verification. The results show that the application of R_3 (△) and station-based correction can help to improve the station The consistency of the magnitude of the network was measured, so that the M_L magnitude error decreased from 0.27 to 0.22.
