Melting permafrost flowing like lava in Tibet
« on: September 10, 2017, 02:46:18 PM »
This video is circulating on Wechat & Weibo, melting permafrost, flowing like lava in #Tibet.

People who say it cannot be done should not interrupt those who are doing it.

There is a link to a paper dated Sept 8.  Can anyone translate?

Using google translate, I got this:

Yushu a pasture mountain collapsed, turf flow like a river

September 7, Qinghai Yushu. Said the more than a county ranch occurred in the mountain collapse, debris flow wrapped in the destruction of turf on the grasslands of the flow. The disaster caused part of the family economic losses, a car was slightly damaged, the ranch is being relocated.

See Dr. Dave Petley's Landslide blog: 
11 September 2017
 A dramatic earthflow video from Dimye village in Tibet

...
Whilst the posting links this event to permafrost degradation, this is not clear to me.   
...
It is not possible to say whether this is indeed a peat landslide, or something similar in an organic soil, or a permafrost slide.  Unfortunately, I doubt that more information will become available in the near future.  But it is a great video.


Petley's next article includes this quote from a published paper about certain Alaskan landslides near Glacier Bay:
We hypothesize that degradation of rock permafrost is the primary factor that controlled the timing and size of rock avalanches in the Glacier Bay region.

So: melting permafrost flowing like lava over a cliff.   :D
