Pick a city, then choose your nuclear device or even an asteroid impact, then see the radius of destruction. Unfortunately, it doesn't seem to allow you to target a particular house.
That is an interesting site. Particularly for a survivalist nut like me!!
It also shows how difficult it would be to nuke the downtown slums without damaging Tulsa's primary financial infrastructure located around 169 and 71st Street! [:P]
Very interesting..........
