Hollywood heroes have an uncanny ability to outrun bombs. For the rest of us, it’d be helpful to know how far away we’d have to get from a nuclear blast to really be safe. The Ground Zero web application uses Google Maps to show the size of the damage caused by different nuclear bombs. Just search the map, hit the button that says, “nuke it,” and figure out how far you have to run. Or, if you’re like Indiana Jones, you could just hide in a fridge.
