Overview aerial image: The detachment zone is located at the far upper left on Piz Scerscen.

Telephoto view of Piz Scerscen from Alp Ota. The detachment zone is roughly in the centre of the image (see next image). Some debris of the landslide can be seen at the lower right on Vadret da Tschierva.

Close-up from the previous image. Colours in the shaded area have been enhanced, making the different hues of the newly exposed and older rock sections more distinguishable.

Low-altitude aerial photo facing the front of the landslide deposit. The debris covers large sections of the forefield of Vadret da Tschierva. The bright area at the lower right is a deposit from a 2022 debris flow.

Low-altitude aerial photo facing the western part of the front of the landslide deposit. Just below the centre of the image on the right, brown trees pushed forward by the rockslide can be seen, along with a person on the bright debris flow deposit. Just below the centre of the image on the right, trees (now turning brown) were felled and pushed forward by the rockslide. Also visible is a bright debris flow deposit with Michael Hambrey on it.

Close-up of the lower section of the landslide deposit. The large boulder is also visible in the previous aerial images. A rough estimate based on the aerial images suggests it is about 20 metres wide with a volume of at least 2,000 cubic metres.

Larches and Swiss stone pines destroyed by the landslide. The trees at the back were displaced by the debris, while those in the foreground were affected solely by the pressure wave preceding the actual landslide.

Amidst the trees felled by the landslide lie remnants of a wooden trail marker.
