EARTHQUAKE EPICENTER DETERMINATION USING DELTA T DATA,
Abstract
Theoretical time differences in the arrival of P-waves at different seismic stations around the Pacific were compiled and plotted by digital computer and by hand. Time-difference curves were plotted for each pair of seismic stations; such curves will allow the quick determination of earthquake epicenters. The following seismic stations were used in the compilations: Honolulu, Hawaii; Tucson, Arizona; Hong Kong; College, Alaska; and Sitka, Alaska. Included in this report is a modified version of the spherical hyperbola program that was used in the compilation. Travel-time difference charts are included as appendices for all combinations of the seismic stations listed above. (Author)
