the alabama tornado and underground houses

This is one of the pictures of the devastation caused by the recent Tornado in Alabama. What gets me, is why everyone still adheres to the old way of designing and building houses, especially when there is a good chance a Tornado will come along at some stage and destroy them. Why not build them so they are mostly underground?  The houses would be cooler in summer, warmer in winter, pretty soundproof, and a lot harder to destroy. You could probably get some kind of false windows put in if you wanted, with some kind of periscope device that shows the views from above. Don't even go there if you are thinking about flooding or drainage, as that could easily be sorted.
I tell you, l'm wasted in my job (in more ways than one).
