The Feb 07 flood in India [1] was first thought to be a burst glacial lake but:
> Other reports have suggested that satellite images imply that a landslide may have triggered the events... In satellite images, a 0.5 mi (0.80 km) scar is visible on the slopes of the Nanda Ghunti, a peak on the southwestern rim of the Nanda Devi sanctuary, a wall of mountains surrounding the Nanda Devi massif.

- londons_explore 6y agoI was under the impression that while the exact time of a landslide is hard to predict, it is relatively easy to predict that an area of land might suffer landslides. (ie. by looking at the angle of every layer of rock and looking for any that are near their critical slippage angle) Surely that is checked for all land surrounding any hydro project, and the land stabilized with piles or grout before the hydro project starts?
- danans 6y agoIt appears that the side of a 6000m (20000 ft) mountain collapsed. Clearly this has happened many times through the geological history of the Himalaya - which is arguably the most extreme and dynamic mountain range on the planet - but on human timescales this is an extreme outlier event, so very hard to plan for.
