New insights on the runout of large landslides in the Valles‐Marineris canyons, Mars

Analogy with lab‐scale dry granular flow experiments demonstrates that runouts and deposits heights of Valles‐Marineris (VM) landslides can be scaled on a curve varying primarily with the initial aspect ratio of the mobilized rock mass (before slope failure). This results suggests both that any interstitial fluid played a negligible part in the VM landslides dynamics and that mobility is not an appropriate tool to characterize their dynamics.
