This is a project designed to provide a number of functions related to parsing and processing earthquake ground motion data, building on top of the ObsPy library. Most of the extensions that we provide are to handle strong motion data and related issues.
- Please note, we are in the process of improving the documentation and that there are some incomplete sections.
- The full documentation can be viewed locally by running the
docs/makedocs.shscript. - The documentation is also available here.
- The MATLAB functions included in the
tools/matlabdirectory include a short tutorial
The developers can be reached at gmprocess@usgs.gov.
If you would like to post an issue to ask a question, request a new feature, or report a bug, you can do so at the github mirror of this repository.
If you would like to contribute merge requests to this repository, please let us know and we can add you as a collaborator. This will require that you create an account at code.usgs.gov, which is a more involved process than creating a personal account at gitub.com and posting to the issues on the github mirror.
