DSM COMPLETE SYNTHETIC SEISMOGRAMS - P-SV, SPHERICALLY SYMMETRICAL, CASE

In a previous paper, [Cummins et al., 1994, hereafter referred to as D SMI], we presented theoretical and computational results for calculati ng complete SH (toroidal) synthetic seismograms for spherically symmet ric, isotropic, media. We now extend our treatment to the P-SV (sphero idal) part of the wavefield. No asymptotic approximations are used, an d the synthetics, which include both body and surface waves, can be co mputed for a broad range of frequencies. Examples of synthetic profile s axe presented for a 600km deep source in the IASP91 model for the pe riod range 4-5000s. Such synthetics can contribute greatly to the dete rmination of earth structure from analyses of broadband seismograms.
