STRONGEST One-Punch Man Discussion Thread!

Okay, wow I spoke with Graywords and the translation team about this and the Kanji is indeed Shindo. But 6 on the Shindo scale would also mean 6+, which is "it is impossible to remain standing or move without crawling, people may be thrown into the air" meaning that this earthquake could really be an 8.5 or even a 9. We'll need to discuss this.

Do we have a set-up for converting the Shindo scale into the moment magnitude scale?

Going off Japans time description for a 6- here, it's the same as the USG description of a magnitude 8, and the 6+/7 is similar to that of a nine. I know a magnitude 9 earthquake sounds crazy given the devastation those cause in real life, but it's worth noting that Metal Knight's smaller base withstood a nuclear bombardment with only minor shaking.

I'd suggest quantifying this earthquake as an 8.5 on the low end (above the description of a 6-) and a 9 on the high end. What do you think?

We had this discussion on the webcomic as well. We determined that the area was too small to equivocate it to an earthquake.

Earthquake resistant buildings and such aren't designed to and don't take the full energy of an earthquake, so just shaking/destroying buildings designed to handle them is nowhere near as impressive as affecting them with a fully-sized earthquake.

I believe there was a calculation for the webcomic version of this feat with small city level results, was that deemed valid and if so, is it still around?
 
Just read the translated chapter
Tatsumaki was really gonna cripple the fubuki group over nothing?
She really is an evil goblin lol, she needs to get her ass kicked.
 
Where can I find the bonus chapters with scans like the one that confirms Vaccine Man explosion was 20KM away and such?
 
ByAsura said:
It wasn't a calculation, it was based on using the Shindo scale.

We agreed that it was actually Large Town level, and then we completely removed the feat altogether for this reason.

That means we'll have to calculate right and proper then using what we see on the screen. Problem is, I've never done a feat like this. If anyone knows of any building shaking calculations we have right now, let me know and I'll piggyback off of that
 
Earthquakes occur over hundreds of kilometres from depths of tens to hundreds of kilometres. This is extremely shallow according to the HA themselves, so the amount of energy being received by the city would represent a much greater percentage of the total energy than a real earthquake.
 
DontTalkDT stated that at least 100 meters is necessary for the Earthquake formula to kick in.
 
Kachon123 said:
This just means that the source of the energy is not super deep underground. How does this prove anything?

Because, as I said, buildings aren't actually designed to withstand the entire yield of earthquakes, which are spread over a considerable distance.

Since this telekinetic earthquake is orders of magnitude closer to the surface than a real one, it wouldn't need to be anywhere near as powerful as a real earthquake to shake a building designed to withstand a mag 6 on the shindo scale.
Kachon123 said:
It's much greater than 100 meters.

No it isn't. It's 13 floors.
 
This is the most common method to calculate earthquakes.

The method is identical to that of "Case 2: Natural Earthquakes", just this time instead of the "Total Seismic Moment Energy" (MO)" value our end result is the "Seismic Energy in Waves Radiated from Earthquake Source" value.

The reason one uses that value in this case is that the big energy loss that comes through the movement of the continental plate or similar processes of natural earthquakes is not present here. Instead we can only use the amount of energy that actually takes part in the effects we observer. Hence only the energy radiated in form of seismic waves is relevant for this case.

There's a massive difference between Radiated Waves and Total Seismic Energy, which is the earthquake movement that happens with tectonic plate movement. So yes Total Seismic Energy cannot be used as those Earthquake are from tectonic plate movement from hundreds of kilometers down.

But that is irrelevant for Case 3: Other, it only uses Radiated Waves and not Total Seismic Energy. It doesn't involve hundreds of km of depth of plate movement. This method of calculating Earthquakes is already taking into account this isn't happening hundreds of km below the ground.

Mag 1 Earthquake (Radiated Waves): 0.000476879063098 Tons of TNT

Mag 1 Earthquake (Total Seismic Energy): 9.3198374761 Tons of TNT

See the massive difference from a Radiated Wave quake which is on the surface for vs a real earthquake that happens hundreds of km down below the ground?

That's over a 1900000% difference between them.

From the pixel scaling I've done today I've got a hypocenter depth of 233 meters scaling off the Hero Association.

Thank you. I'll use case 3 with the pixel scaled distance. But the question of the magnitude remains- given the earthquake resistance of the building should I count it as a shindo 7 (8-9) or given the distance do I put it down a tier?
 
Fairly sure it isn't, because we see the floor sizes in the chapter.
 
They're not 40 metres each.

Anyway, let's wait until the next chapter and maybe we'll see if the depth is consistent with the scans.

We also see that the hypocenter is about as deep as the hero association is tall (middle panel, page 7- link isn't working), and since the Hero Association is more than 13 stories tall I think it's just a situation where the entire facility was carved out underneath a 100 meters of rock, from floor 1 to 13. If that's not the case, then the floors must be nonconsecutive at points

Oh yeah, I remember something iconic happening in the webcomic that would give us the depth of this earthquake.

If it were to happen the same in the manga of course.

Oh Saitama busting through the roof? That's a good point but I'd rather not wait two weeks to make the calculation, oh well
 
Actually, is there even a point to this?

Assuming this is applicable and we can use 500+ metres, the result is only 350 kilotons (Large Town level).

(6.9) + 0.0238*0.52569211333475 = 6.9125114723

10^(1.5*(6.9125114723)+4.8) = 1.4749157e+15 J (352.513320638 Kilotons)

There'd be a point for the webcomic, since everyone at this level will be Small Town level+ or Town level (see sandbox), but even Fubuki is already Small City level in the manga.

I get that the hypocenter is really close but the seismic intensity at the epicenter would still be the same, it would make more sense if we assumed at least a Shindo 6+ earthquake, like a magnitude 8.5, since a 6.9 (realistically a 5+) shouldn't be noticeable if what the guy said is true. I personally believe that Metal Knight could build an extremely earthquake resistant structure since we're already figuring out how to build structures strong enough to withstand moment magnitude 8 earthquakes, and his OG HA was able to tank nuclear+ kinetic impacts with less notable shaking on a much smaller structure.

I'm thinking something like...

(8)+0.0238*0.52569211333475 = 8.013

10^(1.5*(8.012511472)+4.8)= 6.588*10^16 joules or 15.7 megatons, 7-B.

Only Agent Finger would scale as of now

if he gets a profile (doubt) what’s it even gonna be called?

If we never see this character again, I can understand why you might think he doesn't deserve a profile. But I'm fairly certain he's going to be a recurring character and have another fight at some point.

Even if he doesn't he's potentially a useful powerscaling benchmark that we can compare future dragon level fighters and their feats to.

EDIT: Oh you thought Tatsumaki killed him... fair enough, she did really stab him in the eye with a poison needle at mach 500.
