Terrestrial and extraterrestrial landslide size statistics

We present the size statistics of landslides on Earth, Mars, the Moon and Mercury. We used two existing landslide inventories for New Mexico (USA) and for Valles Marineris, Mars, and two new inventories of lunar and Mercurian landslides. Failures on the Moon and Mercury were detected and mapped along the internal walls of impact craters. The statistical distributions of the extraterrestrial landslide area were exploited to compare the results with similar distributions obtained for terrestrial landslides.
