Slumps caused by thawing ground on Mars and Earth
The Planetary Geomorphology Working Group of the International Association of Geomorphologists has a rather nice article online comparing the landforms caused by slumping during thawing of the ground with similar features that have been seen on Mars. The article is available here:http://www.psi.edu/pgwg/images/dec09image.html On Earth, thaw slumps occur in permafrost areas like Alaska. This is an oblique aerial image of these features, taken from the site above: The Natural Resources Canada …

Intriguing long runout landslide in Death Valley
Thanks to reader Gregory T. Farrand who brought my attention to a very intriguing feature located in Death Valley in California. This is a feature that was first identified and mapped as a long runout landslide by Michael W. Hart. Greg and Michael, together with Brian Olson and Phil Shaller, are currently studying this slide, which they are terming the “Eureka Valley Landslide”. The source rocks for the landslide are …

Mars Odyssey image of landslide
Although landslides on other planets have not been a major theme of this blog, there is an interesting area of science that focuses on these intriguing phenomena. Of course a great deal of this research is quite difficult given our poor knowledge of the conditions on and in the slopes when they occur. The availability of increasingly high resolution imagery is however helping in the understanding of these features. There …
