Region 1 in Fig. 1 in Anhur showing outcropping, consolidated terrains, and smooth surfaces (from images acquired with the orange filter on 25 March 2015 (left) and 10 February 2016 (right). The March 2015 image has a lower spatial resolution (1.7 m px⁻¹) than that obtained in 2016 (1 m px⁻¹), and it is reprojected onto the shape model to match the observing conditions of the February 2016 image. Thus the left- and right-side images have the same spatial scale. The main surface changes are delimited by polygons A1–A3, the fragmentation and appearance of boulders is indicated with B1–B4, and the new scarp and a changing structure are also indicated. A bright patch (BS2) is also visible in the canyon-like structure in the February 2016 image. The region A3 is in shadows in the image obtained in March 2015, but was imaged with better observing conditions in May 2015, as shown in Fig. 3. See the online movie, which shows the morphological changes between these two epochs.
