摘要
选取2009—2015年内蒙古测震台网速报的46个M≥4.1地震,依据《地震震级的规定》(GB17740—2016)中关于量取地震宽频带面波震级M_(S(BB))的各项条款,重新量取M_(S(BB)),与中国地震台网中心编目结果产出的M震级和M_(S7)震级进行对比分析,结果显示:M_(S(BB))震级与M_(S7)震级的一致性较好。
According to the items for measuring seismic broadband surface wave magnitude M_(S(BB)) of general rules of earthquake magnitude(GB17740—2017), the broadband surface wave magnitude of chosen 46 M ≥ 4.1 earthquakes from quick reports of Inner Mongolia seismic Network, from 2009 to 2015 are remeasured. Then the results are contrasted the with China Seismic Network M magnitude(surface wave magnitude M_S) and M_(S7) magnitude. The result shows that the M_(S(BB)) magnitude is in good agreement with the M_(S7) magnitude.
