Calc And yet another berserker (AGK)

Emperor teigu's activate its feral mode and then throws a huge nuke that packed enough heat to vap a crowd of folks from dozens of meters away

let's calc the power of this nuke i guess
the distance range we have on this calc

33445.57-50927.52 m

keep in mind that this is an extreme low end as the nuke went far past the battlefield and could be seen from the other side of the country by wave and kurome
so i will just go with the high end distance at once
50927.52 m

panel height is 320 px
nuke diameter is 137px
compact angscalling go
2*atan(137/(320/tan((70/2)deg)) 33.374975 deg
30534 meters for nuke diameter
now this is using what angsizing gave me
we have on panel statements that the capital area is 200000 km^2

R^2=A/pi
R^2=200000/pi
R^2=63661.9772
R=252.313252 km
which using the 33.374975 degrees we have gives us
151280 meters for the nuke diameter
now this is a mushroom cloud that comprovadely irradiates heat and vaps humans even without touching them
so i will use near total fatalities as a low end and nuke radius airburst as a high end
nuke radius via angscalling is 15.267 km
nuke radius via statements is 75.640 km

also there is this awesome mid end from a poster on the commentaries below

I would disagree with the low end because that is pressure killing the human not heat and that would just kill him not vaporize him.

I went another way to calc it, which is close to your high end.

There is a paper done on vaporizing a human from The Centre for Interdisciplinary Science, University of Leicester back in 2013.
http://www.physics.le.ac.uk/jist/index.php/JIST/article/view/23/18

Saying it takes approximately 2.99 Gj applied evenly in short amount of time to vaporize a whole human being. (Note by vaporize they mean separate all atoms of the human body.)

So from this I just use the inverse square law. The energy of the blast would spread in all directions 'evenly'. (well not evenly, since part will bounce back from the ground this and that, but to simplify things it is mostly evenly)

So radius = 15,267 m
Area = 2,928,985,860 m^2
Human body surface area < 2 m^2
just the front surface area < 1 m^2

So X = Area / H_area * Vap_energy
X = 8,786,957,580,000,000,000J
or 2.1 gigatons

feral teigu nuke near total fatalities=182 megatons-23.368 gigatons
feral teigu nuke fireball airbust=4.473-245.331 gigatons
feral teigu nuke surface area method=2.1 gigatons

so feral teigu is either city level+ or island level+
