APPL ICATION OF WAVELET ANALYSIS TO PRECURSOR OBSERVATION AT YONG'AN SEISMIC STATION

    Graphical Abstract
    • Abstract
  • The precursor observation data at Yongan seismic station are analyzed using wavelet analysis methods.The results show that the wavelet analysis method is effective in rejecting pulse interference, data fluctuation and co-seismic deformation waves from observation data and getting clear original trend of precursory data and make it easier to identify short and long term pre-earthquake anomaly in the future.
