Schenk and M. H. Bulmer identify the deposit of a possible landslide off Euboea Montes. The thick deposit at the northern flank is interpreted to be from a landslide, and they further point to the shape of the northern flank as evidence for slope failure. The estimated volume of the debris apron is about 25,000 km3. If this is true, then Euboea Montes has arguably one of the largest debris aprons in the Solar System, of a size similar to those formed by landslides in Valles Marineris, around Olympus Mons on Mars, or submarine landslides on Earth.
