Automated Source Depth Estimation Using Array Processing Techniques

摘要

In this paper we present a routine that exploits the power of seismic arrays and cepstral techniques to estimate the depth of an event directly from the observed seismograms. A discussion of the pertinent geophysical assumptions, cepstral processing algorithm, stable peak identification via 'cepstrograms,' false alarm reduction methodology, and our array-based depth estimation routine is presented. An analysis of several shallow events is performed and compared to results produced by a standard location algorithm, waveform forward modeling, and previously published solutions.
