Apologies for the lack of posts of late – due to Covid-19, and its associated secondary hazards, my day job is taking all of my time at the moment.\u00a0 Anyway, on Saturday Brent Ward tweeted a fantastic set of aerial images of the Koidern landslide<\/a>, in the Yukon of Canada.\u00a0 This is one of the most spectacular landslides of the year to date:-<\/p>\n https:\/\/twitter.com\/GeoBrentatlarge\/status\/1302019475668115457<\/p>\n .<\/p>\n Brent has posted a thread of images of the Koidern landslide, which includes this pair of tweets showing the structure of the landslide (mollards are cones of rock avalanche material) and the landslide dam:-<\/p>\n https:\/\/twitter.com\/GeoBrentatlarge\/status\/1302019684447944704<\/p>\n .<\/p>\n The Koidern landslide is a very interesting rock avalanche, showing quite high mobility.\u00a0 Note the very clear main track of the landslide, as well as the areas on either with lower levels of debris.\u00a0 It appears to me that a part of the landslide has super-elevated on the outside of the first bend.\u00a0 Some landslide debris has also spilled out on the true right side of the track.<\/p>\n The images show that the landslide dam has overtopped; given its size and the remote location the hazard is very low.<\/p>\n .<\/p>\n This is a pretty cool video of a recent rockfall.\u00a0 Note the very large boulder that leaves the dust cloud on the right hand side and disappears down the valley:-<\/p>\n Friday at Cima Canali at Pale di San Martino (Dolomites). Not so high up as the Drus and judging by the debris cone below not the only #rockfall<\/a> ever at this spot. But quite sizable and in sync with the increasing seasonal warming of high #mountain<\/a> rock walls. pic.twitter.com\/RvAxF63E2V<\/a><\/p>\n — Jan Beutel (@jan_beutel) September 6, 2020<\/a><\/p><\/blockquote>\nQuickslide 1: A spectacular rockfall at Cima Canali at Pale di San Martino in the Dolomites<\/span><\/h4>\n
