Abstract
In a previous paper, [Cummins et al., 1994, hereafter referred to as DSMI], we presented theoretical and computational results for calculating complete SH (toroidal) synthetic seismograms for spherically symmetric, isotropic, media. We now extend our treatment to the P‐SV (spheroidal) part of the wavefield. No asymptotic approximations are used, and the synthetics, which include both body and surface waves, can be computed for a broad range of frequencies. Examples of synthetic profiles are presented for a 600km deep source in the IASP91 model for the period range 4‐5000s. Such synthetics can contribute greatly to the determination of earth structure from analyses of broadband seismograms.This publication has 10 references indexed in Scilit:
