If so this might tell us something about the strength and degree of saturation of the various layers:<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_14770\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2015\/03\/15_03-Oso-1-e1426058799970.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-14770\" class=\"size-full wp-image-14770\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2015\/03\/15_03-Oso-1-e1426058799970.jpg\" alt=\"Oso landslide\" width=\"640\" height=\"346\" \/><\/a><p id=\"caption-attachment-14770\" class=\"wp-caption-text\">Oso landslide<\/p><\/div>\n<p>.<\/p>\n<p>And the lack of dust in the air is interesting too.\u00a0 It doesn&#8217;t appear to be windy, suggesting that this was probably because the landslide did not generate huge amounts of dust, supporting the idea that the landslide was very wet at the time of the failure.<\/p>\n<p>But the most interesting aspect really is the sense of calm.\u00a0 You might think that in the aftermath of the landslide everything was very chaotic, but this video shows a shockingly tranquil scene.\u00a0 <a href=\"http:\/\/www.king5.com\/videos\/news\/local\/2015\/03\/09\/new-oso-video-shows-slide-5-minutes-after-disaster\/24634739\/\">There is a news report about the video on K5<\/a>, which includes some additional footage, in particular showing the rescue efforts that were going on at the time.\u00a0\u00a0 The small number of fire fighters, survivors and passers-by had started to try to rescue people caught on the edge of the landslide. Of course at this point the main rescue teams had not arrived.\u00a0 Apart from these well-organised rescue attempts &#8211; I have massive admiration for these first responders, who had to deal with a dreadful situation, and coped wonderfully &#8211; it would be impossible to know that the landslide had just occurred.<\/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>A new video has emerged showing the aftermath of the Oso landslide a year ago.
