пThe idea that Orochi tore out a huge piece of the mantle, hiding the whole mass in nowhere really confused me, so I decided to give my version of the calculation of this feat. The principle is similar to the feat of Conan, which pushes the lake apart.
But in such calculations, I did not see that people took into account the mass of the core liquid, which was also diluted to the side. And this is evidenced by its curved shape, which I circled in the lower corner.

The distance to the surface of the Earth's core on the first frame = 5155 km = 241 pixels.
I use the cylinder volume formula to find out the amount of dispersed mass.
Cylinder diameter = 21 pixels = 5155/241 * 21 = 449 km;
Radius = 224.5 km;
Cylinder height= 21 pixels = 5155/241 * 21 = 449 km;
Volume = 224,5^2*3,14 * 449 = 71 057 296,465 km^3;
The density of the Earth's core = 13,000 kg/m^3;
Cylinder weight= 71 057 296,465 * 13 000 * 1 000 000 000 = 9,2374485 × 10^20 kg.
In addition, the attack opened up the outer core of the Earth:
The distance to the surface of the Earth's core in the first frame = 5155 km = 380 pixels;
Cylinder diameter = 46 pixels = 5155/380 * 46 = 624 km;
Radius = 312 km;
Cylinder height = 232 pixels = 5155/380 * 232 = 3147 km;
Volume = 312^2*3,14 * 3 147 = 961 912 523,52 km^3;
The density of the outer core = 9,900/m^3;
Cylinder weight= 961 912 523,52* 13 000 * 1 000 000 000 = 9,522934 × 10^21 kg.
Now let's move on to the calculation of the kinetic energy. I will take 4 time segments as the high, middle and low end of the feat.
1. The lowest end = 30 seconds;
2. Low end = 20 seconds;
3. Mid end = 15 seconds;
4. High end = 10 seconds.
5. Extra end = 5 seconds;
To assume that the attack lasted about a minute is simply stupid, because Saitama would not have waited so long while the enemy literally shakes the entire planet. I believe that the last 2 ends will be more logical, given that the Bald Man watched as he was attacked. The argument that the action can take a minute, since the other characters reacted is very strange, because the consequences of the attack could not disappear immediately after its cast. But to avoid an outlier, I suggest using the middle and high end.
1)The lowest end:
Beam speed = 5155/30 = 171,833 km / sec = 171 833 m / sec;
The height of the first cylinder = 449 km;
Timeframe = 449 000/171,833 = 2,6 seconds;
Core scattering velocity = radius/time = 224 500/2,6 = 86346 m / sec;
KE1 = (86346^2 * 9,2374485 × 10^20)/2 = 3,4435507 × 10^30 joules;
The height of the Cylinder = 3147 km;
Timeframe = 3 147 000/171 833 = 18,3 seconds;
Core scattering velocity = radius/time = 312 000/18,3 = 17 049 m / sec;
KE2= (17 049^2 * 9,522934 × 10^21)/2 = 1,384008 × 10^30 joules = 330,7 Exatons of TNT = 5-C+
2)Low end:
Beam speed = 5155/20 = 257.75 km / sec = 257,750 m / sec;
The height of the first cylinder = 449 km;
Timeframe = 449 000/257 750 = 1.74 seconds;
Core scattering velocity = radius/time = 224 500/1, 74 = 129,022 m / sec;
KE1 = (129 022^2 * 9,2374485 × 10^20)/2 = 7,6886408 × 10^30 joules.
The height of the Cylinder = 3147 km;
Timeframe = 3 147 000/257 750 = 12.2 seconds;

3)Mid end:
Beam speed = 5155/15 = 343.66 km / sec = 343 660 m / sec;
The height of the first cylinder = 449 km;
Timeframe = 449 000/343 660 = 1.3 seconds;
Core scattering velocity = radius/time = 224 500/1, 3 = 172 692 m / sec;
KE1 = (172 692^2 * 9,2374485 × 10^20)/2 = 1,3774203 × 10^31 joules.
The height of the Cylinder = 3147 km;
Timeframe = 3 147 000/343 660 = 9.15 seconds;
Core scattering velocity = radius/time = 312,000 / 9, 15= 34,098 m / sec;
KE = (34 098^2 * 9,522934 × 10^21)/2 = 5,536032 × 10^30 joules = 1,32 Zettatons of TNT = Low 5-B
4)High end:
Beam speed = 5155/10 = 515.5 km / sec = 515,500 m / sec;
The height of the first cylinder = 449 km;
Timeframe = 449 000/515 500 = 0.87 seconds;
Core scattering velocity = radius/time = 224 500/0, 87 = 258 045 m / sec;
KE1 = (258 045^2 * 9,2374485 × 10^20)/2 = 3,0754802 × 10^31 joules.
The height of the Cylinder = 3147 km;
Timeframe = 3 147 000/515 500 = 6.1 seconds;
Core scattering velocity = radius/time = 312 000/6, 1= 51 147 m / sec;

5) Extra end:
Beam speed = 5155/5 =1031 km / sec = 1,031,500 m / sec;
The height of the first cylinder = 449 km;
Timeframe = 449 000/1 031 500 = 0.43 seconds;
Core scattering velocity = radius/time = 224 500/0, 43 = 522 093 m / sec;
KE1 = (522 093^2 * 9,2374485 × 10^20)/2 = 1,2589769 × 10^32 joules.
The height of the Cylinder = 3147 km;
Timeframe = 3 147 000/1 031 500 = 3.05 seconds;
Core scattering velocity = radius/time = 312 000/3, 05= 102,295 m / sec;
KE = (102 295^2 * 9,522934 × 10^21)/2 = 4,9825262 × 10^31 joules = 11,9 Zettatons of TNT = Low 5-B
It looks like this returns Orochi, Saitama, Genos and the rest of the top-tier 5 tier. And considering how easily Saitama suppressed this attack and using the last end and the quote that he can destroy the planet, then it can be scaled to the basic 5-B.
