## Comparison of ray-theory synthetic seismograms
with finite differences in 2D velocity model UNCONFORMITY

**Ludek Klimes**
### Summary

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.

### Keywords

Velocity model, elastic waves, synthetic seismograms, ray theory,
finite differences.
