Calc When Supernatural Battles Become Commonplace - Hatoko brings up magma

Calculations

Hatoko combines earth and fire manipulation together to make lava, which Chifuyu stops by creating more rock on top of where the lava would erupt. I was wondering about this one for a while, if Hatoko brought lava up from below or just melted the ground directly below her. However, going by the original novels, this magma was originally deep below the ground, as Chifuyu creates new stratum to slow it down.
Given it bursts through different stratum of earth, that would mean it requires coming from deep underground. Not only that, but Chifuyu was fast enough to create whole new stratum to halt the eruption. Hatoko is 16 as of the start of the series, and the average height of a 16 year old Japanese girl is between 157cm and 158cm (or an average of 157.5cm, or 1.575m).
647 pixels = 1.575m
1 pixel = 1.575m/647 = 0.00243431221m
0.00243431221m X 113 = 0.27507728m
35 pixels = 0.27507728m
1 pixel = 0.27507728m/35 = 0.00785935086m
0.00785935086m X 1095 = 8.60598919m

object degree size = 2*atan(Object_Size/(Panel_Height/tan(70/2)))
= 2*atan(1095/(1615/tan(70/2)))
= 0.621682239 rad
= 35.6197684930317067 degrees

Enter that through the time-tested angscaler and we have a distance of 13.394m to Hatoko. The area of ground with magma bursting up goes further than that, but there isn't really a way to find the full length unfortunately. Next up for the distance the magma travelled. The average thickness of the Earth's crusts is between 30km and 70km.

L = 30km + 70km
= 100km/2
= 50km (50,000m)

V = lhw
= 8.60598919 X 13.394 X 50000
= 5763430.96m^3

Fragmentation of rock is 8000000 joules per m^3.

V = 5763430.96 X 8000000
= 4.61074477e13 joules
= 11.019944478967496 kilotons

That's our low end of solely using fragmentation, but what about the lava itself? We see it starting to emerge just seconds later (and the novelization even says it would had been instant had not Chifuyu made other stratum & bedrock to slow it down).



Timeframe is 2 seconds and 22 frames.

T = 1s/24
= 41.6666667ms X 22
= 0.916666667s + 2s
= 2.91666667s

T = 50000m/2.91666667s
= 17142.8571/340.29
= Mach 50.3771992

As for the weight of the magma, as there are various densities of magma, we'll go with the average rhyolite, because that weighs the least. Rhyolite magma weighs between 2180 and 2250kg per m^3, which averages out at 2215kg per m^3.

M = 5763430.96 X 2215
= 1.27659996e10kg

KE = (0.5)mv^2
= (0.5) X 1.27659996e10 X 17142.8571^2
= 1.87582034e18 joules
= 448.33182122370936895 megatons

Final Results
Hatoko brings up magma (energy - low end) = 11.02 kilotons
Hatoko brings up magma (energy - high end) = 448.332 megatons
Hakoto brings up magma (speed) = Mach 50.377
