New guidelines for contribution to the GEM Global Active Faults Database have been published on GitHub. They are reproduced below.

The GEM GAF-DB is a public, open-data project and contribution is quite welcome.

The GEM GAF-DB is a compilation of a set of regional and global fault datasets; most of these are not produced by GEM, but instead have been collected from external sources. The final database is built with a Python script that handles the compilation. Therefore, there is no single, permanent dataset that one can modify to contribute.

Instead, contribution can take several forms:

• Addition to the 'miscellaneous' dataset. This dataset is intended to capture individual faults that are not present in the regional dataset for an area, though the dataset has worldwide scope. If you have studied a fault that isn't present, or you have new data on a fault that is already present, this is likely the best option.

• Modification of a regional dataset. This option is best if you have data for faults in an area that is covered by one of the fault catalogs maintained by GEM or that is otherwise open for modification (e.g., HimaTibetMap or the Active Tectonics of the Andes catalogs).

• Addition of a new regional dataset. If you have a dataset that covers some region with higher fidelity or more data than the existing coverage of that region, it's easy to incorporate this data into the GAF-DB compilation.
