yes, it happens. One of the reasons is that buildings don't fly ;-) They are standing on the ground, exercising pressure on the ground, and if you remove the pressure (=building) at one side it might happen (depending on the force and the ground) that part of the ground below an adjacent building "moves" into this now "pressure-free" area. It happens almost always, but it depends how much it does if the other buildings still remain or collapse... Still I wouldn't say that in these cases the building couldn't stand on its own, it is a technical error of not having stabilzed the ground below sufficiently. Cheers, Martin
