STUDY OF SEISMIC PROPAGATION PATHS AND REGIONAL TRAVELTIMES IN THE CONTINENTAL UNITED STATES

Abstract

The Geological Survey recorded seismic waves generated by LONGSHOT at five stations on the Alaskan mainland, two stations on the Aleutian chain, five stations in Colorado, one station in Nevada, and one station in California, in addition to locations where we have a permanent-station recording capability. Distances ranged from 440 km at Attu to 5987 km at Trinidad, Colorado. Good quality seismograms were recorded at all stations. Reduced traveltimes of first arrivals are shown with a comparison with the standard Jeffrey-Bullen curve. The time scale has been reduced by a velocity factor of 8.1 km/sec.
