Examples

TomoATT_path/examples provides several examples to demonstrate how to use TomoATT.

Toy examples include:

• eg1_seismic_tomography: invert traveltime data for subsurface velocity heterogeneity and azimuthal anisotropy (see Introcution);
• eg2_earthquake_location: invert traveltime data for earthquake locations and origin times (see Introcution);
• eg3_joint_inversion: invert traveltime data for both model and earthquakes (see Introcution);
• eg4_1d_inversion: invert traveltime data for 1D model as an rough initial model (see Introcution).

Real-data examples include:

• realcase1_regional_tomography_California: real-data region seismic traveltime tomography in the California near Parkfield (Chen et al., 2025 ; Chen et al., 2023 ) (see Introcution);
• realcase2_teleseismic_tomography_Thailand: real-data teleseismic traveltime tomography in the Thailand (Chen et al., 2023 ) (see Introcution);

Example Python scripts for process input and output files

• scripts_of_generate_hdf5_model: several Python examples to generate the model file in HDF5 format for TomoATT (see Introcution);
• scripts_of_plotting: several Python examples to visualize the output file after inversion (see Introcution);

Users can directly run the examples in the path of each example simply by

./run_this_example.sh

Here, we will demonstrate how to run each example step-by-step.
