Wave propagation and source parameters in eurasia. Final technical report, 15 April 1993-14 October 1995
Regional seismograms from the Soviet JVE explosion were modeled. The tectonic release part was composed of stress relaxation and secondary high frequency sources. Pn, Sn, Rayleigh and Love waves were modeled. SsPmp phases were discovered in regional waves and modeled using ray theory and synthetic seismogram computations. Teleseismic source inversion using broadband SV waves was investigated. It was found that SV/SH inversion can constrain source radiation patterns as well as P/SH inversion although information on receiver structures is very important. Smaller earthquake events become accessible for waveform inversion using SV and SH waveforms. Theory and computational methods were explored for the problems of plane wave propagation in plane layered, general anisotropic media and point sources in heterogeneous media.
