most astonishing landslide video of 2016 showed the <a href=\"https:\/\/www.youtube.com\/watch?v=mB6x18IzUJA\">Almaluu-Bulak landslide in Kyrgyzstan<\/a>.\u00a0 <a href=\"https:\/\/blogs.agu.org\/landslideblog\/2016\/05\/01\/landslide-loess-kyrgyzstan\/\">I wrote about it at the time<\/a>, and also managed to <a href=\"https:\/\/blogs.agu.org\/landslideblog\/2016\/05\/02\/kyrgyzstan-loess-landslide\/\">pin down the location<\/a>.\u00a0 The video is worth seeing a second time:<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/mB6x18IzUJA\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>.<\/p>\n<p>This was the second, larger, event in the sequence, both of which occurred on 27th April 2016.\u00a0 One person was killed.<\/p>\n<p>Last month, the <a href=\"https:\/\/www.gearthblog.com\/blog\/archives\/2017\/03\/kyrgyzstan-landslides-google-earth.html\">Google Earth Blog wrote about this landslide<\/a>.\u00a0 The prompt was new imagery in the tool that captures the before and after situation of this landslide, and the adjoining area.\u00a0 And wow, this is worth a look.\u00a0 The easiest way (assuming you have Google Earth) to view the images is via this <a href=\"https:\/\/www.gearthblog.com\/wp-content\/uploads\/2017\/03\/Landslides.kml\">KML file<\/a>.\u00a0 They have even mapped some of the landslides, though a quick inspection shows that there are many, many more.\u00a0 Indeed this is a landscape that is dominated by landslide processes.<\/p>\n<p>But, in terms of the Almaluu-Bulak landslide itself, the imagery is fantastic.\u00a0 This is the image collected in November 2016:-<\/p>\n<div id=\"attachment_23433\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\"

is a most beautiful example of a flowslide.\u00a0 The deposit at the toe is very similar to the deposits seen at the toe of some flume experiments when the flume toe is planar, unrestricted surface, although others will be able to better comment on this.<\/p>\n<p>A really interesting aspect is the before and after comparison of the source area.\u00a0 This is an image after the event:<\/p>\n<div

in the foreground, and behind the crest of the landslide scar.\u00a0 But look at this image, taken two months before the failure event, from the same perspective:<\/p>\n<div id=\"attachment_23458\"

class=\"wp-caption-text\">Google Earth imagery of the source of the Almaluu-Bulak landslide, taken two months before the failure<\/p><\/div>\n<p>.<\/p>\n<p>Note the multiple arrays of cracks in the source area.\u00a0 This was a landslide that was developing over a long period.\u00a0 Interestingly, these cracks do not correspond to the current back scar.\u00a0 But we know that two failure events occurred in close succession.\u00a0 I would hypothesise that these crack define to source of the first landslide, whilst the second occurred because of toe release by the first.<\/p>\n<p>The large cracks behind the scar suggest that there is a risk of a third, possibly even larger, event at this site, but that can only be ascertained with a more detailed analysis that involves fieldwork.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content
