Question about explosions at different locations

[CNBA3]

Question about certain explosion feats for celestial bodies like the moon.

The type of explosion in question would destroy the moon at the center of it. However on it’s surface would not be enough to do so.

What method of calculation would be done in this kind of scenario? Similar to the movie Armageddon but more straightforward.

Question about certain explosion feats for celestial bodies like the moon.

The method of calculation doesn't change. It's still a Moon level (5-C) feat calculated using GBE

GBE is an Intrinsic Property, GBE is the minimum energy required to overcome a celestial body's own gravity and disperse its constituent parts to infinity. It's a property of the Moon itself, based on its mass and radius. To destroy the Moon, you must output enough energy to overcome its GBE, regardless of where that energy is applied. The standard accepted value for destroying our Moon is 29.6 Exatons of TNT.

Attack Potency isn't a measure of energy density at a specific point; it's a measure of the total energy released by the attack. Whether the explosion happens at the core or on the surface, if the end result is the complete destruction of the Moon, the total energy output had to be at least equal to its GBE.

Detonating an explosive at the core of a target is simply a more efficient way to destroy it. It ensures the energy is distributed more evenly throughout the body's mass. An explosion on the surface is less efficient, as much of the energy radiates out into space.

However, the tiering system is based on the result. If Character A destroys the Moon with a surface-level blast and Character B destroys it with a core detonation, they both performed a 5-C feat. Character A's attack might have even needed to be stronger in total energy output to compensate for the inefficiency, but the baseline for the feat remains the GBE.
