Sturzstrom
Type of landslide / From Wikipedia, the free encyclopedia
A Sturzstrom (from the German Sturz (fall) and Strom (stream, flow)) or rock avalanche is a large landslide consisting of soil and rock which travels a great horizontal distance (as much as 20 or 30 times) compared to its initial vertical drop.[1] Sturzstroms have similarities to the flow of glaciers, mudflows, and lava flows. They flow across land fairly easily, and their mobility increases when volume increases.[2][3] They have been found on other bodies in the Solar System, including the Moon, Mars, Venus, Io, Callisto, Iapetus,[4][5] and Phobos.
