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

    Graphical Abstract
    • 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.
