So basically a character creates this crater, same story as always
However i am not gonna use that image for scaling since the quality is quite low and the speech bubble seems to be covering parts of the crater making it difficult to measure accurately as such the only purpose of this scan is to show that there is vapor coming out of the crater right after the attack was used
Anyways
Second scan time
So just a quick note as to why im scaling from the person i am scaling from. There are 11 people there out of which 6 are giants by human standards, 2 are dwarf sized and 3 are regular humans out of which 2 are guys and one of them is a girl. So basically i scaled from someone who seemed to be average in height and assumed them to be the girl
Okay now lets get to actual scaling
Person = 6 px
I am assuming that she is 162 cm tall
162 / 6 = 27 cm per px
Crater diameter = 203 px or 5481 cm
Radius = 2740.5 cm
Height = 82 px or 2214 cm
Volume = pi x 2740.5^2 x 2214 = 52238067478.366 centimeters3
We can see vapour coming out in the first scan so im gonna use vaporization
52238067478.366 x 25700 = 1.34251833e15 joules Large Town level (320.86 kilotons of tnt)
