Synthetic seismograms for an explosive point source in 2-D elastic velocity model UNCONFORMITY are calculated by a 3-D ray method and by 2-D finite differences followed by an approximate conversion from a line source to a point source. The demonstrated differences between 3-D ray-theory seismograms and converted 2-D finite-difference seismograms are discussed in detail.
