In addition to subsequent cratering, southwest–northeast trending fractures, prevalent in this region of Enceladus, cut across Otbah, forming several canyons several hundred meters deep along Otbah's rim. The high level of tectonic activity associated with this fracturing and the formation of the nearby south polar terrain may have also led to mass wasting along the crater's wall, leading to a 3 kilometer wide landslide deposit in the center of Otbah.
