What is SeisFlows?

SeisFlows is an open source seismic inversion package that

  • delivers a complete, customizable waveform inversion workflow
  • provides a framework for research in regional, global, and exploration seismology

Perhaps the easiest way to learn more is to run one of the following examples.

Examples: Available For Download

We have prepared a 2D waveform inversion example that is inexpensive enough to run on almost any laptop, desktop, or cluster. To run this simple checkboard inversion, see these step-by-step instructions.

Some additional examples are available for download. Please review the instructions for the 2D checkerboard test case to get a sense for how to run these other inversions.

Some 2D examples based on the Marmousi model are available here.

A 3D Cartesian checkerboard example is available here.

A 3D global 1-chunk example is available here. Please note, the compressed archive for this example is very large (> 0.5 GB).

At a minimimum, one processer is required for the 2D Marmousi examples, 16 processors are required for the 3D Cartesian example, and 64 processors are required for the global 1-chunk example. See here for more information about running inversions in parallel.

Examples: Available Locally
