CALCULATING FOCUS DEPTH USING SPN PHASE RECORDED ON HEBEI DIGITAL SEISMIC NETWORK

    Graphical Abstract
    • Abstract
  • On basis of seismic wave data recorded on Hebei digital seismic network, using sPn phase, focus depth of two typical earthquakes in Hebei is calculated, the residual error of the two earthquakes is much smaller than that of the result given by China earthquake networks center.Our result indicates that this method can be applied in daily work.
