Latest Google Maps hack: will you survive when the bomb hits?

I'm glad most of the Google Maps hacks I've seen aren't as morbid as this one, but I have to admit, there is something eerily compelling about the High-Yield Detonation Effects Simulator, which lets you choose the epicenter for a bomb attack, set the bomb's intensity and then get a map showing the radius of the bomb's destruction, all in the familiar Google Maps interface. The site defaults to a 100 kiloton bomb detonated over lower Manhattan, and shows that, remarkably, much of the Upper East Side is unscathed (at least until the radiation hits), while much of Hudson County, New Jersey, is wiped out.
