Analysis of the Recoed of Beijing Seismic Intensity Meter Network for the M 4.3 Yongqing Earthquake

  • 摘要: 2018年2月12日河北永清发生M 4.3地震,北京烈度仪台网共35个台站获得有效记录,记录最大峰值加速度的台站为丰台地震台(D0001),峰值加速度为10.76cm/s2,该台距震中约61km。本文对北京烈度仪台网获得的此次地震动记录进行了初步分析,并对3个同台址的强震动仪记录的数据进行了对比分析。结果表明,烈度仪记录计算得出的仪器烈度与强震动仪记录计算的仪器烈度结果具有较高的一致性,可用于烈度速报。
