as the slope moved outwards a tension crack opened, into which the truck could fall.\u00a0 According to the Daily Mail, this landslide occurred in a quarry in Tunceli province, which is in the Anatolia region.<\/p>\n<p>These three videos do rather nicely illustrate the somewhat varied nature of landslides, the reason why so many of us find them to be fascinating.\u00a0 But note that all three have human causes.<\/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>Three new landslide videos have appeared on Youtube: a road slope collapse from Hechi in China, a quarry landslide in Anatolia in Turkey &#038;
