چکیده:

This paper contains cruxes of new theory to solution of linear inversion problem in seismic tomography. The known methods (Lanczos’s and CSSA) take participation in a scheme, which has a likeness with DD tomography. We give a digest of the developed approach testing, which showed the very accurate reconstruction of the complex synthetic model of the fault zone in Western Nagano (Japan). We summarize the DA velocity results are produced from the real data processing. DA displayed the thin main fault plane better than DD method. We also illustrate a comparison of the DA earthquake relocation result with the outcome of a standard LSQR method. That confirms that DA tomography simplifiesthe fault patterns more than the standard approach.
