Improved Procedures for Determining Seismic Source Depths from Depth Phase Information
Abstract
The objective of this research has been to develop an improved technique for estimating the depths of seismic sources at teleseismic distances. Based on this depth estimate, deep events could immediately be classified as earthquakes and further discriminant analysis could be concentrated on the remaining shallow events. Work during this contract has been directed towards further improving and evaluating the automated depth determination procedure developed during three previous contracts. This procedure uses computed travel times to combine depth phase information associated with P, PP, PPP, and PcP arrivals recorded at a network of stations. The resulting depth estimate is better than those obtained by conventional methods, which do not make full use of all this depth phase information.
