Get Nepal working again with shipping container houses certified by The Fish. They should be welded onto deep screw piles, and it's good to have a basement in the mountains for boulders. They can have this sign:
There is a one in a million chance that we will experience a great earthquake while you are here. This is the place to survive it. It has been certified by The Wacky Harold. You will notice that everything is fastened down. When the earthquake wakes you up by throwing you out of bed, please proceed to our basement where we have all the supplies necessary.
You can't have naked tourists running out screaming in the night. Also the floors should be soft in the bedrooms. :)
