河北永清M4.3地震北京烈度仪台网记录分析
摘要:    2018年2月12日河北永清发生M4.3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。

Analysis of the Recoed of Beijing Seismic Intensity Meter Network for the M4.3 Yongqing Earthquake
Abstract:      An earthquake with magnitude 4.3 occurred on 12 February 2018 in Yongqing County, Langfang City of Hebei Province.There are 35 seismic stations that received the acceleration data in the Beijing seismic intensity meter network.The nearest station is Fengtai station,with an epicentral distance 61km,and peak ground acceleration was 10.7cm/s2. The farthest station is Sankuaishi station,with an epicentral distance 158km, and the peak ground acceleration was 2.1cm/s2.The preliminary analysis shows that the data recorded by the seismic intensity meters were clear and complete. Data recorded by the seismic intensity meter and the acceleration meters at the same station are comparable to each other.
