Umm what? Yes it is, and that doesn't even include the explosion going beyond the screen. The anime is in 2D, so trying to argue the depth of the explosion is pointless, but we saw how the explosion reached the POV anyway, and the burden of proof is on you to show that the depth of the explosion is not similar to its width. I already asked the very people who created some of these formulas and in this case it is perfectly fine to use the explosion airburst formula, and what aftermath do you mean? The storm dispersion? We get even higher results using that.
I really, really want to see how the hell did you got City level yields when absolutely no one here got results lower than Mountain level even while using the old measurements.
I will leave my calc here using the lowest cloud density, now please show us your City level calculation.
