曹妃甸地震台网天然地震与爆破波形记录特征

摘要

In this article, the seismic waveform recordings of Caofeidian Seismic Network since its inception have been summarized. The waveforms of natural earthquake and chemical explosion and mine blast that it received are compared. The difference between natural earthquakes and blasting seismic is illustrated with examples. The comparisons with waveform of the natural seismic and blasting show many differences in P wave touches, wave attenuation, amplitude and cycle. Through the spectrum analysis of waveform, the two types of seismic activity were further distinguished.%统计曹妃甸地震台网成立以来记录的地震波形资料,对比天然地震和化学爆炸、矿爆的波形,发现天然地震与爆破震相特征在P波初动、周期、波形衰减及振幅等方面有很大不同,并对波形进行频谱分析,进一步识别天然地震及爆破.
