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
