For a 'fun' exercise, the NUKEMAP is illustrative on the effects of these horrific devices. Try dropping various payloads on your location to have a peek at what is at stake.

To note:

NK's latest public test would kill ~33 mi^2. Not a lot of fun.

The US's Castle Bravo kills ~1,400 mi^2, most of the DMV region.

The USSR's Tzar Bomba kills ~6,600 mi^2, nearly the entire LA basin.
