Shirou becomes Ginrou through an unknown necromantic ritual, where he absorbs the blood of thousands of his brethren. This causes a huge explosion of blood. We can scale the size of the bloodburst from the size of the pit. First the get the pits depth. The average length of a horse is 8 feet, or 2.4m.
1111 pixels = 2.4m
1 pixel = 2.4m/1111 = 0.00216021602m
0.00216021602m X 3018 = 6.51953195m
Now we can finally get to scaling the dimensions of the blood burst.
1 pixel = 6.51953195m/217 = 0.030043926m
0.030043926m X 1173 = 35.2415252m
Now for the timeframe of the expansion of the blood bulb.
T = 1s/24
= 41.6666667ms X 11
= 0.458333334s + 2s
= 2.45833333s
T = 35.2415252m/2.45833333s
= 14.3355357m/s
Finally, for our mass. This is the easiest part, as we're outright given the number of bodies in the pit. The average person has 1.2 to 1.5 gallons of blood, or an average of 1.35 gallons.

We also have the number of fellow beastmen who's blood got absorbed by Ginrou; 2000.
M = 1.35 X 2000
= 2700 X 3.7854kg
= 10220.58kg
KE = (0.5)mv^2
= (0.5) X 10220.58 X 14.3355357^2
= 1050203.35 joules
Let's also add the GPE. First, we have to find the centre of gravity for the hemisphere.
CG = 3 X r/8
= 3 X 35.2415252/8
= 13.2155719m
E = 13.2155719 X 9.807 X 10220.58
= 1324639.43 joules
Now, to add the two together...
E = 1050203.35 + 1324639.43
= 2374842.78 joules
Final Results
Ginrou's blood bubble = >2374842.78 joules
That's it? I'm honestly surprised at how low this is, but given there's an explosion afterwards, the final result would ultimately be even higher.
