Introduction[]
Big Boom, Video here
Values[]
I don't know how tall Enid is but she's described as a tall female in her late teens so i'll take average height for an 18 year old
Enid Height = 1.63 meters = 23 px
Crater diameter 1 = 160 px = 11.34 meters
Crater diameter 2 = 293 px = 20.76 meters
Crater height = 68 px = 4.81 meters
The shape looks like a conical frustum to me so
Volume = 500549000 cc
Calculation[]
I'll use two ends, Fragmentation and V fragmentation
Low end = Frag = 0.96 tons of TNT (Building level)
High end = V frag = 8.25 Tons of TNT (Large Building level+)
Edit[]
Apparently i made a mistake with the values in the calculator or something so credit to Zanybrainy2000 for this bit
V = 1001097191.23 cm^3,
Low-end (Fragmentation): 1001097191.23 x 8 = 8008777529.84 Joules, or 1.914143769082218 Tons of TNT
Building level+, and a really high-end of building level, too.
High-end (Violent Fragmentation): 1001097191.23 x 69 = 6.90757062e10 Joules, or 16.50949000956 Tons of TNT
City Block level
Final Results[]
Enid survives an explosion =
Low end = Frag = 0.96 tons of TNT (Building level) (8-C)
High end = V frag = 8.25 Tons of TNT (Large Building level+) (High 8-C)
Low-end (Fragmentation) = 1.914143769082218 Tons of TNT (Building level+)
High end (Violent fragmenatation) = 16.50949000956 Tons of TNT (City Block level)
