Open AccessWidespread small grabens consistent with recent tectonism on Mercury
Since Mariner 10 first imaged Mercury in 1974, tectonic landforms dominated by shortening structures have been extensively documented. Contractional tectonism on Mercury is thought to have begun early in the p...

Open AccessThe impact of ground-ice thaw on landslide geomorphology and dynamics: two case studies in northern Iceland
As consequence of ongoing climate change, permafrost degradation is thought to be increasingly affecting slope stability in periglacial environments. This is of growing concern in Iceland, where in the last de...

Experimental evidence for lava-like mud flows under Martian surface conditions
Large outflow channels on ancient terrains of Mars have been interpreted as the products of catastrophic flood events. The rapid burial of water-rich sediments after such flooding could have led to sedimentary...

Open AccessSustained fluvial deposition recorded in Mars’ Noachian stratigraphic record
Orbital observation has revealed a rich record of fluvial landforms on Mars, with much of this record dating 3.6–3.0 Ga. Despite widespread geomorphic evidence, few analyses of Mars’ alluvial sedimentary-strat...

Open AccessWater induced sediment levitation enhances downslope transport on Mars
On Mars, locally warm surface temperatures (~293 K) occur, leading to the possibility of (transient) liquid water on the surface. However, water exposed to the martian atmosphere will boil, and the sediment tr...

Open AccessHistory and Applications of Dust Devil Studies
Studies of dust devils, and their impact on society, are reviewed. Dust devils have been noted since antiquity, and have been documented in many countries, as well as on the planet Mars. As time-variable vorte...
