When I was researching this morning I found papers related to this kind of risk from at least 2000. Given 20 years there could have been things done I think. And there is a lot of settlement on the tops of the ranges in that area too.. Maybe the roads have to be on the river valley, but not everything else. People living there could have been offered alternative land to move out of the path of it.. monitoring and early warning could have been set up.. at the checkpoint, if it had to be there, there could have been a big evacuation tunnel carved into the hillside, or something.. I guess Nepal doesn't have a lot of resources though. The same thing even happened a year ago in the sample place, but at a smaller size https://www.stimson.org/2025/investigating-an-emerging-clima...
Flat lowland is great because it's cheap and easy to build on, and not a hassle to actually use.
Ridgelines and slopes are terrible to build on (and often use) because there is little to no actual flat usable area without extensive construction. They also tend to be unstable and slide/erode.
That said, if I was in that area, of course i'd never build/live on anything but the highest ridgeline or slope around.
One of those 'long term/outlier risks cause daily costs' type of things. :s
