NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a tongue of debris at the base of the wall of a large crater in Terra Tyrrhena. The tongue is the combined product of landsliding and emplacement of crater ejecta—a ~3 km (1.9 mi) wide impact crater formed on the rim of the larger crater and, when it did, it caused the movement which created the tongue. About one third of the crater that caused this can be seen near the southwest (lower left) corner of the image.
Location near: 21.1°S, 270.0°W
