"The landslides on Iapetus are a planet-scale experiment that we cannot do in a laboratory or observe on Earth," said Kelsi Singer of Washington University. "They give us examples of giant landslides in ice, instead of rock, with a different gravity, and no atmosphere. So any theory of long-runout landslides on Earth must also work for avalanches on Iapetus."

Huge and destructive landslides have been discovered on Iapetus, one of the moons of Saturn.
These huge landslides can travel far further than similar landslides on Earth, up to 30 times the distance that the material has fallen. Known as 'long-runout landslides', the phenomenon has been a matter of great debate among scientists."The landslides on Iapetus are a planet-scale experiment that we cannot do in a laboratory or observe on Earth," said Kelsi Singer of Washington University. "They give us examples of giant landslides in ice, instead of rock, with a different gravity, and no atmosphere. So any theory of long-runout landslides on Earth must also work for avalanches on Iapetus."
Saturn's moon Iapetus frequently plays host to a huge type of landslide or avalanche that is rare elsewhere in the Solar System, scientists report.
