Study on the Calibration Function and Azimuth Correction of Hebei Local Earthquake Magnitude

  • 摘要: 基于2016—2020年河北测震台网记录的941次ML≥2.0地震事件为数据源,计算单台震级平均偏差,通过震级偏差频次趋势、量规函数及震源方位等方面分析影响震级偏差的因素。量规函数校正后,震级偏差绝对值在0.2以内的样本数占比由58.74%提升至62.20%,基于校正数据拟合出切合河北省台站特点的量规函数。在此基础上,以测震单台为中心平均划分为12个区间,分别计算不同方位震源的震级偏差值,发现不同方向的震源对单台震级偏差影响具有一定规律性。除去53个空值区间及样本数量为1的无法计算平均值的47个区间,其余752个区间的震级偏差值|$ \Delta M_{{\rm{L}}nm} $|≤0.2的区间有526个,占比为69.95%,经校正后各区间的震级平均偏差值有所下降,|$ \Delta M_{{\rm{L}}nm}$|≤0.2样本数占比提升至74.77%,说明方位角校正有必要且有意义。
