The landslide was captured in a remarkable video by a member of a road clearance crew who were at the scene at the time.\u00a0 <a href=\"http:\/\/www.idahostatesman.com\/news\/nation-world\/national\/article62694072.html\">The Idaho Statesman describes it as follows<\/a>:<\/p>\n<blockquote><p>\u201cWe were just up there doing some routine road maintenance,\u201d said ITD transportation technician Bret Edwards.\u00a0 The video initially just shows rocks tumbling down the hillside onto the highway. Then a larger piece of the hill begins to move, and you can hear Edwards shouting as he runs away from the massive landslide. The entire hillside sloughs off and the camera spins around.\u00a0 When all was done, dirt, rocks and trees covered a 500-foot stretch of the road about 40 feet deep.<\/p><\/blockquote>\n<div><a href=\"https:\/\/www.youtube.com\/watch?v=tKAlOcZpl4s\">This is the video of the Elk City landslide<\/a>:<\/div>\n<div>.<\/div>\n<div><\/div>\n<div><\/div>\n<div><\/div>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/tKAlOcZpl4s?rel=0\" width=\"480\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<div>.<\/div>\n<div>The Idaho Transportation Department posted this great image of the landslide on their Twitter account on Monday:<\/div>\n<div>.<\/div>\n<div><\/div>\n<div><\/div>\n<div>\n<div id=\"attachment_17895\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-17895\" class=\"size-full wp-image-17895\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2016\/02\/16_02-Elk-City-1-e1456643471814.jpg\" alt=\"Elk City landslide\" width=\"640\" height=\"463\" \/><p id=\"caption-attachment-17895\" class=\"wp-caption-text\">Aerial view of the Elk City landslide as captured by the Idaho Transportation Department<\/p><\/div>\n<\/div>\n<p>.<\/p>\n<p>This a shallow rockslide, probably in deeply weathered rock.\u00a0 The really interesting aspect of the video is the way that the final movement event developed, yet again showing an increasing event rate of smaller falls and slides as the underlying landslide mass accelerated.\u00a0 Even then it was not obvious to the road crew that a major collapse was imminent.\u00a0 As the image above shows, removing the debris will be a large and expensive task.\u00a0 It will be interesting to see if the adjacent slopes are suffering from stability issues as well.\u00a0 And note that the the crown (top) of the landslide there is unstable and displaced material that has yet to fail.\u00a0 This material will need to be managed as failure would lead to it being deposited on the road once again, and as such it is a significant hazard.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>On 18th February the Elk City landslide, a large rockslide, was captured on video by a transportation worker in Idaho, USA<!-- AddThis Advanced Settings generic via filter on wp_trim_excerpt --><!-- AddThis Share Buttons generic via filter on wp_trim_excerpt --><\/p>\n","protected":false},"author":22,"featured_media":17895,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[469,339,963,725,136,48],"class_list":["post-17894","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-landslide-report","tag-featured","tag-idaho","tag-landslide-video","tag-north-america","tag-rockslide","tag-usa"],"_links":{"self":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts\/17894","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/users\/22"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/comments?post=17894"}],"version-history":[{"count":0,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts\/17894\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/media\/17895"}],"wp:attachment":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/media?parent=17894"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/categories?post=17894"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/tags?post=17894"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
