Question about attack potency

[Scottycj256]

I'm collecting feats for calcing Strike the Blood as a verse, and I have a question.

What level of AP would affecting a 180 square kilometer construct be considered? City level, Mountain level, or Island level?

 

[Scottycj256]

what about causing an earthquake with a size of 180 square kilometers?

 

[Thelastmlg]

1. We need to know how tall it is for the volume and the material, also what is affecting in this context.

2. How hard was the earthquake at the edges?

 

[Scottycj256]

man, calcing this verse is harder than i thought lol

 

[Scottycj256]

for the first example, the construct is a man-made island with a city on top of it, with support pillars underneath it extending underwater by at least 12 levels, possibly far more

 

[Thelastmlg]

I can use rock values for that, but i still need a number for it's height, a picture would help

 

[Blahblah9755]

We also would need to know what you mean by “affecting”.
For the Earthquake, could it be felt on the edges, and if so was it felt outdoors or indoors?

 

[Scottycj256]

It's felt both outside and inside on the structure itself.

Also the height for the center of the island, Keystone Gate, should at least 50 floors, which should be 182 meters, which would be half the height of the empire state building, but half of Keystone Gate is submerged underwater since it's built to absorb the shock of ocean waves and sea winds. Every other building on the island is at most 12 floors high, which is 43 meters, and the island itself is sea level.

 

[Scottycj256]

It could be more though since the height of a floor depends on the type of building

 

[Thelastmlg]

If the island is 180 km squared than the buildings won't add into it.

If affected means a earthquake we just need the diameter of the island and how hard was the earthquake.

If there is no diameter, what's the shape of the island.

 

[Scottycj256]

It's this weird ass shape, also I don't know if it's showing at all so here's a backup link:
https://static.wikia.nocookie.net/strike-the-blood/images/f/f8/Strike-the-Blood-1-5.png/

 

[Scottycj256]

It's probably going to be something incalculable if the shape is anything to go by.

 

[Thelastmlg]

The link doesn't work as well, try to upload on imgurl

 

[Scottycj256]

Here you go

 

[Scottycj256]

Like I said the shape is so odd I'm not sure if it can even be calced

 

[Thelastmlg]

Was the entire island, even parts that are kinda de-attached, affected by the earthquake?

 

[Scottycj256]

Yes

 

[Thelastmlg]

Good, let's just slap a cricle since that's close to the shape the earthquake won't jump into the air to cross them.

Area of circle = pi x r²

180000000 = 3.14 x 7571.

So the radius is of 7.5 km, now we need to knoe how hard was the earthquake around the island.

 

[Scottycj256]

It probably wasn't that hard around the edges of the island due to Keystone Gate absorbing the shockwaves

 

[Scottycj256]

It probably would have had an adverse effect on the rest of the island if there wasn't a dampener like Keystone Gate present

 

[Thelastmlg]

It absorbing them doesn't matter much since the energy was still there, we need to find out the magnitude felt at a distance so we need to know how hard was the island shaken.

 

[Scottycj256]

The STB discord says that the novels don't state the exact magnitude so ****.

 

[Scottycj256]

Can we still calc it without a concrete magnitude

 

[KLOL506]

For an earthquake to be felt by normal humans, it'd need to be at least Magnitude 4, but I see sources that as low as Magnitude 3 would also work (But for a large population to feel it, magnitude 4 sounds right).

If islands get detached, but sort of small, then my ballpark estimates would sort of put it around Magnitude 6 or 7.

 

[Scottycj256]

So it'd be at least magnitude 4, possibly magnitude 5, since the MC and another person feel it from another district on the island all together.

 

[Scottycj256]

Magnitude 5 would be about 2 quintillion joules, which rounds out to 478 tons.

Damn, Strike the Blood fodder hax is Multi-City Block Level

 

[Scottycj256]

With 9-B for humans and demons and at least 8-A for MC and Familiars, we can only go up from here lmfao

 

[Thelastmlg]

You don't need the actual magnitude, just showings of how hard i felt, then we can decide on it, so let's use 4.

(Magnitude at distance) + 1.1644 + 0.0048*r = Richter Magnitude of Earthquake

4 + 1.1644 + 0.0048 × 7.5 = 5.2004

Energy = 10^1.5 × 5.2004 + 4.8 = 3.9865756e+12 joules, 8-A+

 

[Scottycj256]

Now I can create a barebones sandbox for the MC and apply the AP calc

And then I can see if I can get a calc evaluation for it and apply it to an actual profile wooooo

 

[Scottycj256]

I'll probably apply "At least 9-B physically, at least 8-A, likely Low 7-C with Familiars" to him.

At least, when I get home at 2:30, I'm on my phone at school texting back and forth.

 

[Scottycj256]

But yea, all I really need to do is get a solid feat for calcing the speed for Strike the Blood, as well as lifting strength, and it'll be good.

 

[Blahblah9755]

Regarding the earthquake, if it’s easily noticed by people outside, it should be at least magnitude 5, not magnitude 4, so magnitude at distance would be 6.2004 and energy would be 10^14.1006=1.2606659e+14 joules, or Town level

 

[Scottycj256]

Oh wow I see, Fire Emblem hello?

Fire Emblem has town level fodder that's the joke

 

[Scottycj256]

So for now I'm going to apply both the Multi-City Block Level calc and Town level calc with the former being "at least" and the latter being "possibly"

 

[Scottycj256]

does a thread like this count for the calc evaluation page?

 

[Scottycj256]

oh wait, I'd need to like make some kind of blog with evidence alongside what was discussed in this thread wouldn't I?

 

[Blahblah9755]

Just noticed that mlg and I used the wrong magnitude at distance formula, since distance was less than 60km.
Formula should be: (Magnitude at distance) + 0.0238*r
For low end:
Magnitude = 4+7*0.0238 = 4.1666
Energy = 10^(1.5*4.1666 + 4.8) = 1.12176012975e+11 joules, City Block level
For high end, magnitude is 5.1666
Energy = 10^(1.5*5.1666 + 4.8)= 3.547317e+12 joules, Multi-City Block level+

 

[Thelastmlg]

Bruh, i literally found the radius of 7.5 km and still uses the wrong one, forgot the area was the 180 one somehow
