Tables of extended distances for PP and pP

Abstract

This paper is the third in a series extending Byerly's method of determining the direction of faulting in an earthquake to deep focus earthquakes and permitting the use of secondary P phases. Here tables of extended distances are presented for the reflected rays of PP and pP, for earthquakes of all focal depths down to 0.12 R. The tables are consistent with earlier ones for P, PKP, and PcP, so that the several phases can be used in a single solution.
