Résumé:

<p>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.</p>
