My friends at Planet Labs<\/a> have very kindly collected a high resolution SkySat image of the landslide – and oh my, what an image this is:-<\/p>\n Planet Labs<\/a> SkySat image of the aftermath of the Mount Silberhorn rock avalanche in New Zealand. Image copyright Planet Labs<\/a>, used with permission.<\/p><\/div>\n .<\/p>\n Clearly the source of the landslide is in the northwest of the image, with the slide moving towards the east and south.\u00a0 Note the clearly evident rock avalanche phase in the early part of the track – the image also picks up the dust staining of the snow around the landslide from this phase.\u00a0 In the lower part of the track the movement has transitioned into sliding, and there are the finger-like structures at the toe that might be associated with slow creep sliding at the end of the movement.<\/p>\n On the steep slopes of Mount Silberhorn there are a small number of separate landslides – one is toe the immediate south of the source area, with the debris moving towards the south.\u00a0 There are at least two others in this area.\u00a0 It is possible that these were triggered by the same process as for the main Mount Silberhorn rock avalanche, but I suspect that it is more likely that these were induced by the vibrations from the main landslide.<\/p>\n Perhaps the most remarkable thing about this image, which was captured on 12 January 2021, is that there is no post-event snowfall onto the landslide.\u00a0 This allows the features to be seen with ease.<\/p>\n .<\/p>\n![\"The](\"https:\/\/blogs.agu.org\/landslideblog\/files\/2021\/01\/21_01-Silberhorn-1-1.jpg\")
