Estimation of Direction of Wavefront Propagation and Apparent Velocity Using Earthquake Signals Recorded in Small-Size Dense Seismic Arrays

Abstract:

This paper presents that the cross-correlation method is used for estimating the direction of wavefront propagation and the apparent velocity for seismic signals in the small-size dense seismic array. The near earthquake signals samples adopted from US Geological Survey Parkfield Dense Seismograph Array (UPSAR array) of the U.S are used for analyzing. The results analyzed indicate that the wavefront propagation and the apparent velocity of near earthquake signals can be succinctly and accurately estimated by the method proposed in this paper.
