Comparison of ray-theory synthetic seismograms with finite- differences in 2D velocity model UNCONFORMITY. Journal of Seismic Exploration, 30: 271-279. Synthetic seismograms for an explosive point source in 2D elastic velocity model UNCONFORMITY are calculated by a 3D ray method and by 2D finite-differences followed by an approximate conversion from a line source to a point source. The demonstrated differences between 3D ray-theory seismograms and converted 2D finite- difference seismograms are discussed in detail.</abstract><keywords>velocity model, elastic waves, synthetic seismograms, ray-theory, finite-differences</keywords></article-meta></front><body/><back><ref-list><ref id="B1" content-type="article"><label>1</label><element-citation publication-type="journal"><p>Bucha, V. and Bulant, P.
