He informed that clearing the rocks and land will take some time.\u00a0\u00a0 \u201cI have already asked the construction companies and Hydropower project working in along the highway to fix the problem and they assured to make the highway ready in about five-six days,\u201d said Sharma.<\/p><\/blockquote>\n<p>Judging by images the landslide itself is quite significant in size (via the <a href=\"http:\/\/www.gorkhapost.com\/dry-landslide-obstructs-daram-river-baglung\/\">Gorkha Post<\/a>):<\/p>\n<div id=\"attachment_22114\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-22114\" class=\"size-full wp-image-22114\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2017\/03\/17_03-Righa-1-e1488785310930.jpg\" alt=\"Righa\" width=\"640\" height=\"360\" \/><p id=\"caption-attachment-22114\" class=\"wp-caption-text\">The landslide at Righa in Baglung, Nepal, via the <a href=\"http:\/\/www.gorkhapost.com\/dry-landslide-obstructs-daram-river-baglung\/\">Gorkha Post<\/a><\/p><\/div>\n<p>.<\/p>\n<p>There is also a collection of images of the landslide in a <a href=\"https:\/\/www.youtube.com\/watch?v=_geCNgmfgSE\">Youtube video<\/a> that is available online:<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/_geCNgmfgSE\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>.<\/p>\n<p>Perhaps the most revealing element is this image of the headscarp area of the landslide at Righa:-<\/p>\n<div id=\"attachment_22122\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-22122\" class=\"size-full wp-image-22122\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2017\/03\/17_03-Righa-2-e1488785666999.jpg\" alt=\"Righa\" width=\"640\" height=\"389\" \/><p id=\"caption-attachment-22122\" class=\"wp-caption-text\">The headscarp area of the landslide at Righa in Baglung, Nepal, via <a href=\"https:\/\/www.youtube.com\/watch?v=_geCNgmfgSE\">Youtube<\/a><\/p><\/div>\n<p>.<\/p>\n<p>In common with the images of the landslide deposit, this suggests that the slide is in deeply weathered, dry soil.\u00a0 Such a landslide should in general be avoidable with good engineering practice, if excavation does indeed to be the cause of this landslide.\u00a0 There does appear to be some evidence that the landslide might be associated with a highway and associated works &#8211;
