## Comparison of Fourier pseudospectral method
seismograms and ray-theory travel times
in a simple triclinic model: revealed direct wave

**Vaclav Bucha**
### Summary

We calculate a complete seismic wave field using the Fourier
pseudospectral method in a simple triclinic velocity model.
To identify elementary seismic waves in the complex wave field,
we compute ray-theory travel times. The velocity model is composed
of two homogeneous layers separated by a curved interface.
The anisotropy of the upper layer is triclinic. We show and discuss
results of comparison between seismograms and travel times
for one common-shot gather.

### Keywords
