Inventory and morphometric parameters of landslides associated with nearby impact craters on Ceres

This dataset includes a curated inventory of eight landslides on the dwarf planet Ceres, mapped and measured to enable reproducible morphometric analyses. The inventory was produced through detailed visual interpretation of the high-resolution global mosaic acquired by the Framing Camera on board NASA’s Dawn spacecraft during the Low Altitude Mapping Orbit (LAMO) phase (Roatsch et al., 2017). Altimetric data were derived from the high-resolution global shape model of Ceres produced by Park et al. (2019) using the stereo-photoclinometry technique developed at the Jet Propulsion Laboratory and based on Dawn’s Framing Camera imagery. The processed images reach a spatial resolution of up to 35 m px⁻¹, while the global shape model was generated with a grid spacing of 100 m and a mean height uncertainty of 10.2 m, referenced to the mean ellipsoid (−7.3 km to +9.5 km). All features correspond to landslides previously reported in global catalogs for Ceres (e.g., Schmidt et al., 2017; Chilton et al., 2019; Duarte et al., 2019; Parekh et al., 2021), here re-mapped with a consistent scheme. Following widely used classifications (Varnes, 1978; Hungr et al., 2014), each case is assigned to slides, flows, or complex movements on the basis of dominant kinematics. The dataset is intended to support comparative studies of mass wasting on Ceres, providing harmonized morphometry and provenance for each mapped landform. Potential applications include benchmarking runout and mobility, investigating links with nearby impact craters, and cross-body comparisons of ice-rich crustal behavior across the Solar System.
