SeisFlows

SeisFlows is an open-source, Python-based waveform inversion package that tackles the problems of full waveform inversion, seismic migration, and adjoint tomography.

With a user base in both academia and industry, this package has been used for production scale inversions, some with over a billion model parameters, for research problems related to oil and gas exploration, earthquake seismology and general nonlinear optimization problems.

• SeisFlows is under current active development, and is bundled with other inversion software under the adjTomo organization.

• Documentation, including install instructions, example problems and API, can be found on Read the Docs.

• If you find any issues, have questions, or would like to join the community, please feel free to open up a GitHub Issue or start a discussion.
