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¶
Users with accounts on “tiger.princeton.edu” can run the following inversions without having to download files or recompile executables.
2D Regional and Global
- North America
- Southern California
- Deep Earth
2D Near Surface
- Marmousi offshore
- Marmousi onshore
- overthrust offshore
