Sure. I should have been clearer in what I wrote. From your earlier post, "put it in the tunnels inside a mountain then blow all entrances up". With the geology, you want a place where you can firmly reason about what's going to happen over a long period of time. Maybe there would be sites where you can do the thing of putting it into mountains. But mountain geology is not necessarily stable. Consider how mountains are formed. Your limited choice of sites is more likely to be flat country. (And it'll be desert, in order for the politics to work.)
