This is the catalogue of dust avalanches mapped around the s1222a marsquake. This dataset is associated to the paper : Discussion on seismically triggered avalanches on Mars after the s1222a Marsquake. which is under review for Geophysical Research Letters. Usage of these data requires to cite this paper. The repository contains the avalanche catalogue and the avalanches that have been detected on the post-marskquake images. Both data base are delivered into a pickle file. In addition, the repository contains a Jupyter notebook that read the pickle files and the full resolution of the oblique view of the mapping generated with the Generic Mapping Tools (GMT) available from https://www.generic-mapping-tools.org.
