单台测定中强震震级偏差的修正方法

The Method of Revision Single seismic station Moderate-strong earthquake Magnitude's deviation

选取淮北地震台(简称淮北台)测定中强震面波震级编目MS4.5及以上震例为样本,以中国地震台网中心(简称CENC)的震级参数为标准震级,新定义"二维震级修正法"对淮北台震级进行修正,分析结论显示"二维震级修正"效果显著,且易于操作,对提高单台速报和编目震级的准确性具有现实意义。

This paper edited and corrected the Ms4. 5 and above moderate-strong earthquake＇ s surface wave magnitude of Huaibei seismic station（for short Huaibei station）, contrast with the China Earthquake Netwok Center（for short CENC） magnitude parameter by a standard. Define the method of Two-dimen- sional revision of magnitude, comparative analysis of the two revision methods, we concluded that the method of T wo-dimensional revision of magnitude is remarkable and effectable.
