BBVS-120型甚宽频带数字地震计典型地震波形记录特征

Characteristics analysis on typical seismic waveform: using very-wide-band-digital-seismograph BBVS-120

对太原基准地震台BBVS-120型甚宽频带地震计记录的不同震中距及不同类型天然地震和非天然地震波形进行分析和对比,结果表明,该地震计能够清晰记录近震、远震、极远震及爆破、塌陷等震相,对各类地震具有较好的监测能力,基本实现全频带观测,可为获得丰富的震相资料并提升地震台监测能力及速报质量,提供技术保障。

In this article, the different types of natural earthquake and non-natural earthquake waveform data with different epicentral distance recorded by the very wideband BBVS-120 seismometer at Taiyuan, Shanxi Province are analyzed. The result shows that, the BBVS-120 seismometer can record the waveform of near earthquake, teleseism, extreme distant earthquake, blasting and collapse with different spectrum band. The seismogram recorded is clarity with abundant seismic phase data and promote the capability of seismic station monitoring and earthquake quick report.
