Rays and travel times in a spherical anisotropic earth

Abstract

A study is made of the propagation of stress discontinuities (wave fronts) in a radially inhomogeneous, tangentially isotropic model of an anisotropic spherical medium.

The results are given in the form of integrals for the ray paths and the travel times for the several body-wave phases.

A special case of anisotropy dealt with in Section 2.2 (3) gives rise to considerable simplifications. This case in particular appears to be useful for the construction of travel-time tables for an Earth in which anisotropy occurs.
