MS(BB)、M、MS7震级对比

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MS(BB)的各项条款,重新量取MS(BB),与中国地震台网中心编目结果产出的M震级和MS7震级进行对比分析,结果显示:MS(BB)震级与MS7震级的一致性较好.%According to the items for measuring seismic broadband surface wave magnitudeMS(BB) of general rules of earthquake magnitude (GB17740—2017), the broadband surface wave magnitude of chosen 46M≥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 magnitudeMS) andMS7 magnitude. The result shows that theMS(BB) magnitude is in good agreement with theMS7 magnitude.
