The Application of DFA Method on Near Earthquakes

    Graphical Abstract
    • Abstract
  • The waveform data of the same near earthquake recorded by all the seismic station within jurisdiction are studied using the Detrended Fluctuation Analysis method (DFA). This paper explored the scaling exponents of the sequence before, during, and after an earthquake as well as three components of seismic waves. The value of scaling exponents can reflect the difference of signal between the seismic waves and the background noise.
