摘要

利用中国地震台网数字地震资料,选取国内M_S≥5.3地震波形数据,采用长周期波形拟合方法,快速计算2008年至今86个中强震的标量地震矩M_0和矩震级M_W,并将M_W与GCMT的测定结果及中国地震台网中心测定的面波震级M_S进行对比。结果表明:矩震级与GCMT测定一致,与中国地震台网中心测定的面波震级关系为M_W=0.86M_S+0.63。
The scalar seismic moment M_0 and moment magnitude M_W of the 86 earthquakes with M_S 5.3 since 2008 in China are calculated rapidly,by long-period fitting with the digital data from China Seismograph Network.M_W in this paper are compared with the those from GCMT and with the surface wave magnitude M_S from CENC.It is shown that the moment magnitudes we calculated are in accordance with measurements from GCMT and the relationship between our M_W and CENC's M_S is M_W= 0.86M_S+0.63.
