An extra vote, also you wanted DT to clarify his stance but he hasn't commented yet.What do we currently need to do here?

Okay. Thank you for the reply.
I also think that @KingTempest has expressed problems with how we should scale One Piece after this thread has been finished, and we need new calculations for the highest feats there. Has there been any progress in those regards?

I think the other thread (more general one) should be concluded before this. Especially considering that Bambu thinks One Piece earthquakes should be calculated like Earth.

You got a better option?Hmm. The One Piece planet should logically be far larger than Jupiter, so that seems like a massive understatement.

Do you have prove or reason for this thinking because difference between earth and jupiter is very significance. I always thought one piece planet was slightly bigger than earth but not the levels of Jupiter.Hmm.

One Piece planet is accepted as being 1.4 Million km in diameter

so about same diameter as sun
, ok thanks.

It's nearly twice the diameter of the Sun.so about same diameter as sun
I'm hoping that Oda provides us with a concrete figure one day.

well but nasa website is saying 1.4 million km approximately here.

Ah, I was looking at the wrong figure, thanks.

Yeah, the current calc makes assumptions about the Grandline and Alabasta that ultimately makes the planet size a lot smaller than it actually is, I can't wait for Oda to finally confirm a Solar System sized Blue Planet.

The situation hasn't changed since this previous reply:What do we currently need to do here?
Nothing might get done until the next round of Calc Group Member promotions if nobody is currently that interested in commenting on the topic.

I’m not a staff member, but why are more opinions needed? Both linked calculations added 6.399 to a value that was already in magnitude form, when it was supposed to be a compensation for a value that isn’t. This led the result to be far higher than it should be.
So it’s likely a typo or a conversion error. As the OP suggested, you just need to fix that.

More opinions are needed on how to calculate the feat for a different planet not for that part

Yeah that was initially proposed (those e21 and e22 results) but then proposal got changed into "earthquake formula is designed to work specifically on Earth".

@Floxy178 and @KLOL506 I got a question for yall
The earthquake formula for Total Seismic Energy that the calculators and others use is
10^(1.5×Richter Magnitude)×10^9.091
It stops at 10.5 for earth because earth can't take it
If a planet is bigger, can we just use that instead for total seismic energy?

If we already use 10^4.8 one for different planets then I see no problem with that.

I don't think so. Earthquake magnitude is capped by amount and length of fault lines (limit is around 10) and strength of rocks ( around 9.6). Strongest earthquake is Chilean 1960(magnitude 9.5), and it released 25% of all seismic energy in 20century.
Larger planets are not beholden to first cap, but still are limited by the second (unless directly stated otherwise some way or another).
Come to think of it, we should prohibit use of this formula for anything higher than 9.5 quake

That is wrong. Not the source but the relevance. That 9.6 figure is talking about energy storage ability of rocks from natural tectonic movements. But here we are talking about an external source of energy inserting energy to tectonic plates. A real life example would be if a massive meteorite or some moon/dwarf planet were to collide with the earth, it would cause an earthquake much bigger than 9.6 and destroy most of the earth. External energy is not limited by rock's strength.

Isn't total seismic energy only used for natural earthquakes?
Earthquakes caused by meteor impacts and artificial earthquakes use other formulas, the formula for meteors which is "10^((Richter Magnitude + 5.87)/0.67)" for example calculates the kinetic energy of the meteor from the richter magnitude of the earthquake caused by the impact event (View page 11 for the source), while other artificial earthquakes use the formula for radiated waves "10^(1.5*(Richter Magnitude)+4.8)" rather than total seismic energy.

Earthquakes caused by tectonic plate shaking*

Nay, formulas does not differentiate between artificial and natural. One is for just seismic waves, other is total work. And the meteor one is for converting kinetic energy into seismic energy. It does not work here.
The real problem is that for small earthquakes both Richter and Moment magnitude (Mw) can be used. But for large earthquakes only Mw can be used. Using Richter would lead to a massive lowball because Richter can not meaningfuly differentiate large earthquakes because of saturation. And Calculating Mw requires information we can not know from the series. So we cannot use that. We are stuck with a likely very big lowball.

We have three staff members agreeing with the OP. What are we still waiting for?

I believe that this probably can be implemented whenever the OP is ready. Floxy is now a calc group member after all.

Why are we using total seismic energy for earthquakes created by punching or emanating energy here?
Also for the record, no, moving the tectonic plate physically yourself won't allow you to qualify for total seismic energy. It is only applicable if the tectonic plates themselves rub against each other normally. I asked in the old Godzilla threads involving a MUTO tapping on the edge of a tectonic plate, and it wouldn't qualify anything beyond radiated waves.

That's correct, but if I'm not mistaken what KT asked is more like a general question "is 10.5+ magnitude disqualifier for total seismic when planet is bigger?" rather than a specific feat.
Though, both formulas are still Earth-specific. I'd personally agree to use our formulas with both similar composition and equal or greater size, but it needs to be discussed and accepted in a thread first IMO. If such a discussion thread (or maybe staff thread? Idk) gets accepted I can make recalcs based on that.

I mean, the magnitude ultimately doesn't matter. You can't use total seismic energy for artificial quakes, period.

He didn't say anything about earthquake in question being artificial though. Seems more like a general question to me.
