earthquake location

This is a toy model to invert traveltimes for locating earthquakes (Figure 8a.)

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.

The initial and true models:

The location results:
