Improved Procedures for Determining Seismic Source Depths from Depth Phase Information

Abstract

Implementation of the seismic source depth analysis package at SDAC has been completed. This version includes Calcomp plot output of seismograms, cepstrums, and depth plots, and allows the analyst to easily reprocess an event using different combinations of input data and analysis parameters. Three new processing features have been developed: phase editing, an improved significance level algorithm, and computation of a depth threshold based on data bandwidth. Phase editing permits point-by-point editing of cepstrums, based on phase; the other two features are designed to assist the analyst in interpreting the final depth plots.
