The W-phase package is an extensive source-inversion tool allowing rapid characterization of the seismic source and is a reliable and straightforward method to resolve first-order attributes of large earthquakes. Main contributors are Zacharie Duputel, Luis Rivera and Hiroo Kanamori.

If you use the W-phase package for your own research please cite the following articles:

Currently, the W-phase package is hosted as a git repository available at https://github.com/eost/wphase.git For more details on using Git for W-phase, please refer to this page. If you would like to contribute or if you have any questions/suggestions, please contact us.

The code is based on a Green's function database. Please contact us if you want to use our database (based on the PREM model) or if you need help to build your own for another Earth model.

The installation is described in the W-phase documentation page.

There is a quite complete document in the w-phase documentation and you can also check out the w-phase tutorial page which includes an example of run.
