The author draws a comparison between Krakatoa and the Saturn V, one being a singular energetic event, and the other being a sustained projection of energy. On the one hand, you have a shockwave of pressure differential travelling out from a central point of release, and on the other you have sustained stimulation due to a high-volume controlled dump of potential energy. That the consistent oscillations of the Saturn V can melt concrete and set fire to grass at a distance by disturbing the air and conveying thermal energy through kinetic collisions alone doesn't really seem like a useful correlation to an impulse event that reverberates across the entire atmosphere. If I had my druthers, though, I'd wager that the gravity waves of a supermassive black hole merger, as detected by LIGO, would likely make for a better analogue to the Krakatoa event. The Saturn V engines are loud, but the nature of the concept is probably better modeled by the fact that you can boil water with a high-end kitchen blender or similar food processing appliance.
