摘要
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M_L、宽频带面波震级M_S(BB)、矩震级M_W,与传统震级M_S进行对比研究,为震级测定的连续性提供可靠依据。
IASPEI working group on magnitude is put forward a new magnitude scale and the measuringmethod in allusion to wide band digital seismic records and the characteristics of large dynamicrange. In this paper, earthquakes of magnitude above 4 recorded by Inner Mongolia seismicnetwork in 2010-2015 years are selected to determined local magnitude ML, wide-band surfacewave magnitude MS（BB）, and moment magnitude MW. The comparative study with traditionalmagnitude provides reliable basis for the continuity of magnitude determination.
