INTERPOLATED JEFFREYS AND BULLEN SEISMOLOGICAL TABLES

Abstract

The travel times for all body phases tabulated in the Jeffreys and Bullen Seismological Tables (1958) have been calculated by interpolation for distance intervals of 1 degree at each of the 14 focal depths established by Jeffreys and Bullen. Travel times have been similarly derived for the phases 'diffracted P' (P at distances beyond 105 degrees) and 'PKPPKPPKP,' based on data extracted from the Gutenberg and Richter travel-time charts (1934-1939). The calculations were effected by means of a digital computer program principally employing Lagrange's four-point interpolation formula. This report discusses the techniques involved and presents the fully interpolated tables in a convenient form.
