# seismic tomography
This is a toy model to invert traveltimes for Vp and anisotropy (Figure 8c.)

Python modules are required to initiate the inversion and to plot final results:
- h5py
- PyTomoAT
- Pygmt
- gmt
Run this example:
1. Run bash script `bash run_this_example.sh` to execute the test.
2. After inversion, run `plot_output.py` to plot the results.
