Abstract

Methods for computing synthetic seismograms for aspherical global earth models (i.e., methods for the spherical coordinates) are reviewed. The methods for the spherical coordinates should be applicable to the problems in the Cartesian coordinates. However, formulations in the spherical coordinates are, in general, tedious, and their detailed methodology appears to be unfamiliar with researchers in other studying fields. The purpose of this paper is to review the methods for the spherical coordinates without using tedious mathematics. Due to the limitation of the space, I focus on methods which have been applied to global tomographies. The approximation methods, merits and limitations are discussed.
