Pathing landslide in Yangyang subdivision, South Sikkim revisited: 27Nov2022

Our visit to and report on the 'Very Active Landslide', at Yangyang in South Sikkim, generated much interest from the public at large and more specifically from the people, media and government of Sikkim. As such the 7 min documentary which STH together with Junkeri Studios (Kalimpong) had almost completed required a total overhaul, since much had changed in Pathing.

The landslide, however continued to wreak havoc and we needed to update our videos as well as photos; as such we made another 3 hour trip to Pathing landslides on 27Nov2022. This photo report is from our visit there on the said date:

Probable cause of the landslide and prognosis
As per locals the landslide has been more active AFTER the monsoons rather than when it was raining. An expert whom I spoke to suggested this maybe due to 

  • the weak rock formations such as phyllites and schists in the mountain
  • the steep (almost 60 -70 deg) incline of the slope failure

What the experts and the villagers agreed on was that it was not possible to control or mitigate this slide as such the only choice left for Pathing villagers would be to relocate to a safer place and I am glad to say that the govt is already thinking on those lines.
A glimmer of hope may also come from what the locals told me - that the frequency of rockfall was less for the last few days and that it had not been active for the 3 consecutive nights. So it could also mean that the unstable mass was collapsing slowly which may lead to this slide becoming stable over a period of time.

Location details of slide
Latitude 27° 17' 44.196" N    Longitude 88° 23' 32.874" E
Elevation 1575.60 m

STH together with Junkeri Studios, Kalimpong will be coming up with a 10 min updated documentary which will include extensive drone foot-ages of the landslide, damage to the village and also interviews with affected people in the next week

As always, our thanks to all those who helped in making our second visit to Pathing possible and especially to the people of the village.
