Fractures found on cliffs on comet 67P/Churyumov-Gerasimenko.

The large image on the left shows the Ash region (located on the large comet lobe) in the foreground and the regions of Hathor and Anuket (both on the comet's neck), in the background. The two boxes highlight two small portions of the comet surface, which are shown in greater detail in the two close-ups, with an indication of the physical scale. The top close-up shows a fractured scarp and what appears to be a new fracture (indicated with a yellow arrow) cross-cutting two older fractures (orange arrows). The new fracture is 100–125 cm-wide and is expected to lead to 'mass-wasting' of the fractured scarp. The bottom close-up shows another small fracture (indicated with a yellow arrow) that appears to cut though the scarp edge and the smooth coating on the top, which is a morphologic characteristic of the Ash region.

The image on the right shows a portion of the Seth region exhibiting a similarly fractured scarp (indicated with a white arrow) and a debris field in at the foot of the cliff suggesting a progressive process of 'mass-wasting'.

Non-annotated versions of the individual images and close-ups are linked from the right-hand menu, under "related images".
