2D wave-equation dispersion inversion of surface waves (WD) is implemented by using SeisFlows+SPECFEM 2D.
This is the updated version of SeisFlows for 2D wave-equation dispersion inversion of surface waves.
I provide dispersion.py in seisflows/preprocess/ which is to calculated the FK spectrum and misfit function and create the adjoint source for 2D WD.
- SPECFEM2D
- Seisflow
- Python 2.7
- Follow this instruction to install Seisflow-2DWD.
- install SPECFEM2D
- Set up checkerboard test in
EXAMPLE/checker_2dwd- Make sure that all paths specified in paths.py are correct.
- Run checkerboard test:
