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.
