Comparison of Fourier pseudospectral method seismograms and ray-theory travel times in a simple triclinic model

Vaclav Bucha

Summary

We calculate a complete seismic wavefield using the Fourier pseudospectral method in a simple triclinic velocity model. To identify elementary seismic waves in the complex wavefield, 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 the first results of comparison between seismograms and travel times for one common-shot gather.
