Alright, do over.
Castle is 1.9m, and 227 px, and the crater is 714 px, so
714 / 227 = 3.14
1.9 * 3.14 = 5.9 m / 2 = 2.95
Depth seems to be roughly equal to Frank sitting. Using this, we get a sitting height for Punisher at 73 inches, or 1.8542 meters
Volume of a cylinder yields = 50.69 m^3 (50,690,000 cm^3)
50,690,000 * 0.4 = 20,276,000 J (0.04 Tons)
Now for destruction of building.
Assuming it's a cube, with a height of 1 storey. Storey's vary so I'm using 3.1 meters based off this.
Volume of a square = a3
3.1^3 = 29.791 m^3
Assuming 95% hollowness.
29.791 -95% = 1.48955 m^3 (1,489,550 cm^3)
1,489,550 * 8 = 1,1916,400 J (0.0028480879541 Tons)
So, the building bit is mostly irrelevant. Small Building level.
