Fun with Nuke Map

We always say of New York City, nuke it from orbit. Well, now with Nuke Map, you can:

As you can see...we assumed three warheads (2.2 MTs each) for Manhattan, one on Wall Street, one on the Empire State Building, one up town, and another warhead each for the other four Burroughs. Nuke Map has casualty estimates. We figure 90% of the city would die. That said there's a massive underground subway system and even more tunnels below those. Some would emerge from the rubble.
