Improved Procedures for Determining Seismic Source Depths from Depth Phase Information

reportActive / Technical Report | Accession Number: ADA021931 | Open PDF

Abstract:

Seismic Source depth determination techniques, developed under two previous contracts, were formulated into an automated analysis procedure Differential travel time information, for several propagation modes relevant to the analysis, have been made accessable through 3-D curve fitting.
