Long-runout landslide transport in Valles Marineris, Mars

Post contributed by Jessica Watkins, Dept. of Earth, Planetary, and Space Sciences, University of California, Los Angeles, USA.

Long-runout (> 50 km) subaerial mass movement is rare on Earth but it is one of the most prominent geomorphic processes shaping Valles Marineris in equatorial Mars. It has occurred widely and nearly continuously within the canyon system over the past 3.5 billion years (Quantin et al., 2004).
