Motherglare's Roar (Fairy Tail)

RH likes his trip gigatons so I'm gonna organize this. Plus, accepted calcs don't like RH's blog

I don't really mind using his radius of 14km.

2*atan(tan(70/2)*(770/189) = 141.364237292408

Ignore his 47px value and look at my 17px value.

2*atan(17/(770/tan(141.364237292408/2)))=7.207643128082

Plug those numbers into the Angsize calculator and we get...

1763.5m

Use these measurements to scale the last panel in the next scan, rather than the scaling that's already there. Ignore all lines but the red one.

Dunno if I really agree with scaling from two different panels, but whatever.

(446/55.9464)*1763.5=14058.474m

Height of rock mass
(97.94/55.9464)*1763.5=3087.19m

Length of rock
(13.03/55.9464)*1763.5=410.722m

Width of rock
(6/55.9464)*1763.5=189.13m

vellipsoid4/3)pi*r1*r2*r3
v4/3)pi*(410.722/2)*(189.13/2)^2
v=7692498.736 m^3

For density (rho) I'll use 2700kg/m^3.

m=v*rho
m=7692498.736*2700
m=20769746587.2 kg

PE=mgh
PE=20769746587.2*9.8*6773.223
PE=1378645627828226.54688 J

Now we calc the area of the cross section, which is an ellipse.

Aellipse=pi*r1*r2
A=pi*(410.722/2)*(189.13/2)
A=61009.613 m^2

Now the surface area of the blast.

SAsphere=4*pi*r^2
SA=4pi*(14058.474/2)^2
SA=620906543.5516 m^2

(1378645627828226.54688/61009.613)620906543.5516=
