内蒙古测震台网新震级标度试用

摘要

IASPEI working group on magnitude is put forward a new magnitude scale and the measuring method in allusion to wide band digital seismic records and the characteristics of large dynamic range. In this paper, earthquakes of magnitude above 4 recorded by Inner Mongolia seismic network in 2010—2015 years are selected to determined local magnitudeML, wide-band surface wave magnitudeMS(BB), and moment magnitudeMW. The comparative study with traditional magnitude provides reliable basis for the continuity of magnitude determination.%针对数字地震记录频带宽、动态范围大的特点，IASPEI震级工作组提出新的震级标度及测定方法，本文选取内蒙古测震台网2010—2015年4级以上地震，按照新震级标度测定地方性震级ML、宽频带面波震级MS(BB)、矩震级MW，与传统震级MS进行对比研究，为震级测定的连续性提供可靠依据。
