高台测震新旧台基记录地震及震相特征差异性对比分析

Comparative Analysis of Earthquake and Seismic Phase Characteristics Recorded on the Old and New Bases of Gaotai Station

摘要:

使用相同带宽、同类型地震计BBVS-120观测记录数据，对高台地震台新旧观测山洞的台基环境噪声、地震监测能力及震相记录特征进行对比分析，结果表明，高台测震新山洞的地震监测水平优于旧山洞，部分地区新山洞对于核面反射波的记录更加清晰。

Abstract:

Using the observation data recorded over the same bandwidth and with the same type of seismometer BBVS-120, the base ambient noise, the earthquake monitoring capability, and the seismic phase characteristics of the new and old observation caves of the Gaotai seismic station were compared and analyzed. The results indicated that the seismic monitoring level of the new cave is better than that of the old and that some new caves have clearer records of radially reflected waves.
