href=\"https:\/\/en.wikipedia.org\/wiki\/Piz_Cengalo\">Piz Cengalo<\/a>, a peak located in the Swiss alps on the border with Italy in the canton of Grabunden.\u00a0 This is a peak that has had significant landsliding in recent years, most notably in 2011 when a large landslide involved about 1.5 million cubic metres of rock.<\/p>\n<p>The landslide on 11th September was caught on video from a number of different angles.\u00a0 <a href=\"https:\/\/www.youtube.com\/watch?v=rjy4JTbQqXQ\">Probably the best<\/a> was collected by Roman Christoffel:<\/p>\n<p>&nbsp;<\/p>\n<p><iframe

in particular is fabulous in the way that it shows the evolution of the rock avalanche and associated dust cloud:<\/p>\n<p><iframe loading=\"lazy\"

another landslide that has been caught so well from so many different angles simultaneously.<\/p>\n<p><a href=\"http:\/\/ilgrigione.ch\/notizia.asp?id_articolo=2188\">Il Grigione Italiano has a nice

Translate does a good job<\/a>) about the landslides.\u00a0 This suggests that the 11th September landslide on Piz Cengalo had a volume of about 100,000 to 150,000 cubic metres.\u00a0 As such this is small compared with the events of five years ago, and the runout meant that the damage was limited.\u00a0 Nonetheless, the authorities are clearly (and rightly) mindful of the continued landslide activity at this site and are maintaining the closure of some local hiking trails.<\/p>\n<h5>Posts on a similar topic:<\/h5>\n<ul>\n<li class=\"posttitle srch\"><a title=\"Permanent Link to The Val
