Phu Cuong commune: a major landslide has killed 18 people in Vietnam
Over the last few days, heavy rainfall has affected the northern and central provinces of Vietnam. The most serious incident appears to be a landslide that struck Phu Cuong commune in Tan Lac district, located in the northern province of Hoa Binh. Latest reports suggest that 18 people were killed in this event. Eleven has a good report about the impact of this major landslide:
The villagers were asleep when a massive amount of soil and rocks, triggered by heavy rainfall, rolled down an adjacent hill at about 1am Thursday, the newspaper reported. At least eighteen people, most family members, were buried alive.
One of the survivors, Bùi Văn Dũng, 26, was still shaken when recalling the disaster, 35 hours after it happened.
“We were sleeping. It was pitch-dark,” he told Dân Việt. “I opened my eyes to a loud ‘bang!’ and found myself lying under the sky, my legs buried in rocks. Everything was shaking.”
Horrified, Dũng grabbed a flashlight to find his wife and daughter in the same situation some 10 metres away. With his screams for help muted by rumbling sounds, he used the wood beams that were lying around to dig up the dirt and rocks that were crushing his wife and daughter.
The family then ran out of the area, at the sight of massive rocks rolling down from the top of the Khanh Waterfall.
The best images of this landslide can be found in this article by the IBTimes:

This image, from VietNamNet Bridge, appears to show the site of the landslide:-

Note the enormous overhang (now disappeared) and the very obvious rockfall deposit in the foreground. A major landslide at this site should come as no surprise.
In total the heavy rainfall has left at least 72 people dead, with further rainfall forecast in the days ahead as Typhoon Khanun passes by.
Hi Dave, the last picture isn’t the waterfall where the landslide happened, this one (phu cuong waterfall) is in south vietnam. I couldn’t find the khanh village where the landslide supposed to happen, but i found another picture of the aftermath here :

And I think that the water coming from the center of the cliff (1st picture) has something to tell about the landslide !

I agree that the water flow out of the cliff face is alarming and suggests another slip is not far away. This looks a bit like a piping failure mechanism. What do you think?
In those conditions, it would be very difficult to make any slope stability engineering calculations I think – but then it is pretty obvious that the slope is unstable so any calculations would just confirm that.
The rescue workers are certainly quite brave going into that area.
Yes probably the same mechanism… here’s a link with a video before the collapse :
