"This interactive tool is intended to give an idea of the devastating blast effects of ground-level, shallow subsurface, and low-altitude nuclear weapon detonations. It is relevant to traditional nuclear weapons, potential terrorist attacks, and next generation nuclear weapons such as "Bunker Busters" or "Robust Nuclear Earth Penetrators" (RNEPs). (Despite the name, "Earth Penetrators" will not penetrate far into hard rock and can be considered "surface" bursts when using the bomb calculator.)"
