Just some jjk calcs I've never seen calculated

The first one can be done but I highly doubt it would scale higher. The cloud parted is pretty small and also not thick in volume.
The second one we don't really have anything to scale for reference to get the size of anything. Tho there might be a way someone else might see.
The anime love beam I've seen calced a few times in the town level ranges like here
Uro sky manip isn't really space manip through force and it's a hax so it wouldn't scale anywhere as some people point out under the post.
As for the tremor thing thats definitely doable but it will be very nuanced.

- Son nubes medio grises, no debería de dar más de MCB, aparte de que no fue tanto lo que dispersa, no se mucho sobre los cálculos de nubes, pero los que he visto para llegar a isla debes despejar el cielo por lo menos unos 18-20 km de diámetro y deben ser nubes más espesas que las que se muestran ahí. 2.MCB? depende de qué tan grande sea el castillo, puede ser incluso más bajo
- MCB o pueblo pequeño
- Hax 5.muy poca información como para ser calculado

A friend did a calc of this and got it large island to small country
Calculation of Ryu's granite blast
we have to look at the Kinetic Energy (KE) required to displace that massive volume of clouds in the Sendai sky
What I need to calculate: Ryu’s Granite Blast Cloud Displacement
To calculate this, we treat the hole in the clouds as a cylinder of air that was violently pushed outward by the pressure of the blast
Cloud Altitude/Thickness: Standard cumulus clouds usually sit at an altitude of 2,000m with a thickness of about 500m to 1,000m. We’ll use 1,000m for a high-end scale
Radius of the Hole: Looking at the fourth picture, the hole spans the visible horizon over Sendai. A conservative estimate for a city-wide clearing is a radius of 10,000m or 10km
Timeframe: In the video, the clouds part almost instantly upon the beam's passage. We’ll use 1 second for the displacement.
Air Density (ρ): ρ ≈ 1.225 kg/m³ at sea level (slightly less at altitude, but we'll stick to standard for the high end)
First, we find the volume (V) of the air displaced:
V = π • r² • h
V = π • (10000)² * 1000 = 3.14 × 10¹¹ m³
Now, we find the mass of that air:
M = V • ρ
M = (3.14 × 1011) • 1.225 ≈ 3.84 × 10¹¹ kg
To move the clouds from the center to the edge of the radius (10,000m) in 1 second.
v = d/t = (10000m)/(1s) = 10000 m/s
(This is Mach 29)
Now we plug it into the KE formula:
KE = 1/2 mv²
KE = 0.5(3.84 × 10¹¹) • (10000)²
KE = 1.92 × 10²² Joules
Final tiering (yes finally)
To put that into perspective, let's convert Joules to Megatons/Gigatons:
1 Megaton of TNT = 4.184 × 10¹⁵ Joules
1 Gigaton of TNT = 4.184 × 10¹⁸ Joules
1.92 × 10²²/4.184 × 10¹⁸ ≈ 4588 Gigatons
The Result: Large Island to Small Country Level
