2003 Hulk generates a shockwave by slamming the ground, knocking down cars behind him.
So we see a yellow car behind Hulk before he slams the ground, then the camera switches to behind Hulk where we see 5 more cars being knocked down.
At least 6 cars. We see the crack on the ground extends to our POV, so that's the minimum radius of the shockwave.
The average car width is 71.4 inches or 181.356 cm.
1.81356*6 = 10.88136 m
C = 1.05 (Middle Value)
r - 10.88136 m
ρ = 1.225 kg/m^3 (Density of Air)
t = 10.8816/340.29 (speed of sound) = 0.0319767257339328 seconds
So...
(1.225/0.0319767257339328^2)*(10.88136/1.05)^5 = around 143 198 181.66 Joules, Small Building level
