摘要
选用吉林地震台网正式运行以来记录的18次东北地区m_b(m_B)≥4.0深源地震资料,以中国地震台网地震目录给出的震级为标准震级,进行震级偏差统计分析,得出震级校正值。分析震级差异形成的原因,为吉林地震台网测定东北深源地震震级偏差校正提供参考。
As the magnitudes presented by China Earthquake Networks Center are the standard magnitudes,a statistical analysis on magnitudes deviation of 18 m_b(m_B)≥4.0 deep earthquakes in Northeast China recorded by Jinlin Province Earthquake Networks Center is conducted.Magnitude correction values are obtained.The reason that causes magnitude deviation is analyzed.The result can be a reference for magnitude correction when measuring magnitudes of deep earthquakes by Jilin Province Earthquake Networks Center.
