摘要
对江苏数字地震台网的波形资料,从震相、频谱、振幅比3个方面进行对比分析,找出天然地震、人工爆破、塌陷的不同之处,能够在地震定位过程中快速识别,并将此方法在江苏地震台网实际工作中应用。
The phase analysis is a basic work in the earthquake monitors. Seismic events usually inelude natural earthquakes and artificial blasts and collapses. In this paper, the waveform data recorded by Jiangsu Digital Seismic Network are summarized. The phase, spectrum and amplitude ratio were analyzed in three aread to distinguish among the natural earthquakes, artificial explosions and collapses, in order to quickly identify among earthquakes, artificial explosion or collapses in the earthquake location process. This method has been applied to practical work in the seismic network in Jiangsu.
