This video was posted on Youtube on 11th February 2016. It appears to have occurred at Yaglidere in Giresun, Turkey. The comments that accompany it are in Turkish – Google Translate makes an interesting job of it (I have added some comments):
Giresun–YAĞLIDERE [Yaglidere in the English spelling] recently softened due to rains caused a landslide territory. The landslide occurred on a mountain roadside husband [I think husband is a mistranslation here – something to do with the landslide mass] landed almost flat. Mountain foothills before the break and then began her husband [mistranslation again for the landslide mass?] went down to a part of the river bed. Barely escaped with their lives on the edge of the road.
I think you need to read between the lines a little to understand this one, but if you do it seems quite clear.
The development of the final collapse is certainly dramatic Note how the landslide transitions from an intact sliding block:
Into a fragmented highly mobile mass in just a couple of seconds:
The displacement of the water in the river is certainly impressive. The landslide appears to be in fine grained silts or sands – possibly loess? I cannot find any information about the superficial geology of Giresun.
