摘要
本文利用内蒙古台网中的二十九台短周期微震仪记录的近震资料,分别采用震级残差分析方法和最大震相平均衰减特性估算的方法,对本地区M_L量规函数进行了分析讨论。并计算了本台网内各台站的台基校正值。初步建立了本地区的近震M_L震级系统。通过检验认为,就本地区目前的观测条件和M_L测定方法而言,该震级系统已将M_L测定误差明显减小了。
In this paper, the calibrating function of local earthqukes at Inner Mongolia area is discussed based on the observation data of 28 stations in this area, and by the analysis of the magnitude deviation and the estimation of the average attenuation patterns of maximum seismic phase of near earthquakes. Each station correction is also estimated. Then, the magnitude system of local earthquakes at Inner Mongolia area is set up. The statistical results indicate th average error of magnitude M_L has been obviously decreased by this system.
