Detection, mapping and classification of mass movements on Mars

We are conducting a systematic mapping of landslides in the Valles Marineris, a region of Mars where landslides are abundant. We characterise the mass movements, including deep-seated slides and rock avalanches, flows, rock glaciers, and talus deposits, and we investigate the statistics of landslide size (i.e., area and volume) which we find different for the Martian slides than for the terrestrial landslides. Martian landslides are significantly larger than their terrestrial equivalents, with the proportion of large vs. small slides larger on Mars than on Earth. We have obtained a dependency to link the area and volume of the Martian slides that can be used to estimate landslide volumes in other areas of Mars.
