天津测震台网子台地脉动分析与应用

THE ANALYSIS AND APPLICATION OF EARTH PULSATION AT THE STATIONS OF TIANJIN SEISMIC NETWORK

    摘要
  • 摘要: 利用地脉动信号波形数据,计算了天津台网31个地震台站背景噪声水平、地动噪声功率谱,进一步研究了台站观测环境随时间和季节的变化情况,并对整个台网的监测能力进行了重新估算,同时也对天津周边的一些大震前的地脉动进行了分析,希望能捕捉到明显的震前异常变化。

     

    Abstract: Based on wave form data of earth pulsation,the background voice level of 31 seismic stations in Tianjin is calculated,the power spectrum is given.Furthermore,the station environment changes with time and season is studied,the monitor ability of whole network is re-estimated.Earth pulsation before some strong earthquakes in Tianjin area is analyzed in order to catch obvious anomaly.
