Ryu Granite Blast (Chapter 176)
Recalc of this because of discussions here. In Chapter 176 of JJK, Ryu fires off a granite blast which destroys a large area of the ground.
SunDaGamer helped me find better measurements for the granite blast. The main issue with the old distance is that it measured the distance from Miwa to the end of the street at the bridge but based on some panels where Yuta is running on it we can see that there was no damage on that bridge. Since we don't really know where it started from, it's better to just use the edge of the bridge as the main distance. On top of that, the destruction where Yuta was is closer to the edges of that street so a different width would have to be used.
Using a half ellipsoid formula, the distance above, and the width and …
Mahoraga chases down Sukuna
In Chapter 118 of JJK, Mahoraga hits Sukuna and knocks him outside the curtain (confirmed in the Volume 14 extras) and into a building, chasing him down immediately.
Thanks to the work of others, locations and landmarks for key moments in JJK were marked out on google earth. The specific distance between where Mahoraga hit Sukuna and the building, using the dismantle's size as an indicator of how far he was roughly in the building, the distance would be 398.23 m. That building's location is also outside of where the curtain would be. Opening the image in full will make it easier to see.
Mahoraga almost immediately arrives after Sukuna lands and given the panel he didn't even start moving until around that time so I'll assume a timeframe of a…
Unlimited Hollow Purple Recalc
So, gonna do a recalc of this and my previous calc using a method that M3X suggested since both calcs have different issues. In Chapter 235, Gojo uses an amplified hollow purple to destroy a large portion of Shinjuku. I'm going to be using inverse square law to calculate the energy the building would've taken and then extrapolating that with the distance we have to find the yield of the Hollow Purple.
Using the building in this image, the height of it is 407 px while the width is 166 px. The actual building has a height of 8 storeys which we know cause it's an actual building. The average storey is 3.9 m tall. The building wasn't completely destroyed in the image but the blast was still traveling and it had already reached the back of one p…
Ursen's Durability and Roar
In Total War III, Ursun creates a massive explosion as he's shot by Yuri.
Planet diameter = 4357 px = 12742000 m
Panel height = 326 px
Explosion diameter = 38 px
Corrected planet diameter = sqrt(1-(tan(35)*(4357/326))^2/((tan(35)*(4357/326))^2+1))*12742000 = 1987515.48453 m
1987515.48453*(38/4357) = 17334.3099408 m (radius of 8667.15497041 m)
Using an overpressure explosion with 20 psi:
8667.15497041^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 52325718.5575 tons of tnt (City level)
In Total War III, it's said that Ursun removes winter every year with a roar, so presumably he's removing the clouds across Kislev. Based on some shots in the game, the clouds Kislev appear rather dark so I'll use nimbostratus clouds which have a thickness between …
Power of a Cyclonic Torpedo
In the Ephrael Stern novel, a cylconic torpedo destroys billions of tonnes of rock, so at least 2 billion tonnes.
It was described as melting and vaporizing it so I'll use three ends, one for pure melting, one for vaporizing, and a mid end for both. Rock has a density of 2700 kg/m3 so using that to determine volume, the yield of each end would be:
2000000000000/2700 = 740740740.741 m3 or 740740740741000.1 cm3
Low-End: 740740740741000.1*6174.5 = 4.5737037e+18 J (Large Mountain level)
Mid-End: ((740740740741000.1/2)*6174.5)+((740740740741000.1/2)*25700) = 1.180537e+19 J (Large Mountain level+)
High-End: 740740740741000.1*25700 = 1.9037037e+19 J (Island level)
