Nukemap has more options
 

Guys, nukemap, the nuclear weapons-effects simulator, now has some more options. You can now select the height of burst, and show craters, should you detonate a weapon on the surface or low enough in the air to have a crater. Just click on "Advanced options", and it'll give you those....have fun, fellows!

Oh, I'm having a blast (pun intended). Doing a little "research" on a few hypothetical scenarios and currently nuking Norfolk NAS and the Naval yards.

Well, according to this, if the Soviets just hit those, I MIGHT survive. But if they also nuke Dam Neck Naval Air Station and Little Creek Amphibious Base? Bye-bye cruel world...

Where I am I'm usually safe, its the Fallout on the westerly winds that get me.
