Thanks to some previous scalings, namely Waka finding a size for Tenrou Island and my scaling of Grimoire Heart's ship, I can figure out how much rock this attack destroyed, which will give us a very good idea of what Hade's durability is. I've wondered... he can dish out multi-block attacks, but can he take them? We'll find out in a moment.
In my previous blog, I determined that the height of the ship was 104.278 m. The height of the ship here is 233 pixels compared to 95 for the blast diameter... notice that I measured slightly further off from the origin of the blast, as it seems to increase in size as it moves. However, part of that is perspective, so I made sure I measured pretty close to the origin.
233 / 95 = 2.453... 104.278 / 2.453 = 42.51 m, the diameter of the blast.
Next up...
So then, we see that the depth and width of the rock destroyed are 62 and 64 pixels respectively... I'm just going to say they're both the same for simplicity's sake, as I'm going to be assuming the destruction is a half cylinder, and it's problematic to have circular shape that isn't perfect. So we'll just say that the depth is the half-cylinder's radius is 62 pixels. The blast's radius is 17 pixels by comparison.
62 / 17 = 3.647 * 42.51 = 155.034 m, the radius of the destruction.
Next we need to note the size of the island:

1,072 m according to Waka's scaling.
In the bottom panel, the island is 598 pixels in diameter, compared to the length of the attack's destruction being at 278.
598 / 278 = 2.151... 1,072 / 2.151 = 498.373 m, the length of the destruction.
Volume = 9,932,294.5459m^3
That would be extremely low-end town level...
