Serenity Chasma is the unofficial name given to a large pull-apart fault on Pluto's moon, Charon.
The chasma is part of a major tectonic belt, which involves a series of canyons, scarps, and troughs that traverse most of Charon's encounter hemisphere.
[2][4] The morphology of Serenity Chasma resembles that of rift valleys, indicative of extensional tectonics.
[5][2] Five major landslide sites have been identified within Serenity Chasma, all bound by the largest cliffs of the chasm.
The landslides provide insight into the properties of Charon's surface material; the frictional coefficient of the landslide material is rather low, ranging from 0.15 to 0.31, comparable to terrestrial debris flows, rock avelanches, and pyroclastic flows.
