The Millennium Earl completely erased Edo, it totally disappeared, the structures, the landscape, life in general, even the ground has been seared to glass, perfect annihilation. We'll look at the blast's radius first.
Edo = Tokyo's old name.
Yes, Tokyo isn't circular, but the blast was, and it had to cover every bit of Edo at the very least to completely erase it as it did, so taking the half of the distance between the two farthest (roughly) points in Edo as the radius of the blast is logical.
This is Edo from the end of the 19th Century, as this is the date of D.Gray-Man's setting:
Distance between the two farthest points in end-of-19th century Edo = 298 pixels = 12.9565217391 kilometres ≈ 13 kilometres
∴ Blast radius = 6.5 kilometres
The ground (sand) was totally seared into glass, we have to take that (melting of sand) into account.
Volume of sand melted = area (m^2. the area the blast covered) * thickness (m. For safety, we cannot assume that anything more than the surface has been scorched, so we'll go with a very conservative thickness of 0.0254 metres (1 inch)) = (6500^2*pi)*0.0254 = 3371400.1562 metres^3
Ambient temperature (taken as average room temperature) = 296.15°K
Latent heat of fusion (Silica. Same reasoning above.) = 3400 cal/mol = 14231.72 J/mol = 236879.494008 J/kg (divided the latent heat of fusion in J/mol by the molar mass in kg/mol) [ source: www.docenti.unina.it/downloadPub.do?tipoFile=md&id=352455 ] (auto-download PDF file) Energy required to melt that amount of sand = (mass * specific heat (sand) * change in temperature [melting point - room temperature]) + (mass * latent heat of fusion) = (5400983050.23*830*1690)+(5400983050.23*23687.494008) = 7.7038947*10^15 joules = 1.841275023900573515 Megatons of TNT= Small City-Level
Since that's the energy required to sear the ground alone, not taking in the total vaporization of all the buildings and structures, it's obvious that the blast is at least City-Level.
Eva01 I don't take quick looks, i thoroughly read. And everything seems fine safe for one assumption, the assumption that Edo is the same size as current Tokyo. I'm pretty sure it's smaller in D. Gray Man given the older look of the buildings and the fact it's set in the 19th century where Tokyo/Edo was still smaller especially in terms of citizens. I'd rather only use the special wards, given this german map of Tokyo from 1896.
So could Tokyo/Edo really have expanded to three times its size in just 110 years? Especially after all the bad earthquakes and tsunamis Japan has been going through for the past decades? It's possible, but we must have a map of the entirety of Edo at hand. Although I will say that Edo should definitely be smaller than modern Tokyo, that I agree with.
And we do (I think). But I can't read Japanese for shit:
Eva01 Given how in the last 110 years the former Edo annexed the western cities according to the history of Tokyo and the english wikipedia page on Tokyo (under geography and administrative divisions sections it says that until 1943 Tokyo was only the special wards). It's like how while growing as a metropolis a big city swallows up the surrounding towns to be part of it, causing it to rapidly expand in size. Given how Tokyo was also destroyed multiple times allowing for easier rebuilding and the populace grew about 8-fold in the last 130 years (from 1.7 million to 13.4 million) it's quite reasonable.
Eva01 Well kinda looks closer to the 23 special wards which was Tokyo until 1943, albeit even smaller. Nice find btw.
BTW i think i found a few better maps.
One from 1898
And one from the in 1908 published Meyers Lexicon Books collection.
Both are in german btw, but it's easier to translate. Just got them by googling "tokyo map end of 19th century" in google images.
First one should be credible given in wikipedia it's described as a German map from 1896 (from the Tokyo page) and it's source has been stated. Hope it helps better with scaling, given it's got the metric system already there on the scale.
There's 3 problems though: 1- I can't view the entire map in full res. 2- The UI for navigating the map and zooming is horrendous. 3- And this is the real problem, the map is so fucking detailed with so much shit on it I can't tell what's what, ironically enough, and I can't see Tokyo's border.
It's a nightmare to work with. It's good as it gets but good luck actually trying to extract any information from it. Fuckin' hell -_-
Eva01 I think you're just better off using that first german map i just showed you, 1896 is pretty close to the end of the 19th century after all and they aren't as detailed but still show the borders good enough.
Dream: Last anime I will be covering is Gankutsuou: Count of Monte Cristo. Will start watching it tomorrow. Not sure how much longer I can keep myself up at this point.
Feb 7, 2020 5:19:21 GMT
Taka: Depending on my energy, I can watched up to 2 AM. Usually with work, I fall asleep on anime series that don't have a lot of action.

Master Menos: Finally got out of the fast food job. It was a graceful exit, but to be honest, I'll miss some of those guys. Got a sprained ankle from it since September, so I'll finally focus on healing that back at the family home.

HungryWorld: Well if anyone remembers what happened to Pingu in the City, with it being joke 10/10 scored on MAL just to get it into the top 10 anime... well now is Ishuzoku Reviewers' turn. Seems that in response to Funimation's cancel people boosted the score hard.
Feb 11, 2020 2:11:38 GMT
Taka: What? That sounds so weird.
Feb 11, 2020 5:36:23 GMT
Master Menos: It's damn awesome to be honest. It shot to 1st Place!

Dream: On the subject of MAL, it looks like the admin are planning to tweak their scoring system for titles to reduce the likelihood of voters artificially inflating the ranking of certain titles.

Master Menos: My V-Day present will be belated this year because I "Had some trouble with ol' Johnny." (That's your hint.)

Dream: The joys of adulthood. Joking aside, plan to at least attempt to wrap up Gankutsuou sometime early to mid next week so I can get done with my Funi voted titles. Afterward, not doing any more voting for a while considering how long this had been taking.
Feb 15, 2020 16:50:30 GMT
Dream: Done with Gankutsuou. Will be working to get a review up for it by sometime tonight.
Feb 16, 2020 20:57:26 GMT
Taka: Great job, Dream! I should do some reviews, too.
Feb 17, 2020 5:24:39 GMT
Dream: Looks like MAL's currently down due to the site getting hit by a major denial-of-service attack, just as a heads up.
Feb 18, 2020 17:55:23 GMT
Taka: I added 2 polls tonight. Also, I wonder why MAL was down. Crunchyroll also had it, too.
Feb 20, 2020 4:05:24 GMT
Dream: Not sure about Crunchyroll. For MAL, the DoS attacks may have been retaliation by those who dabbled into manipulating the site's scoring system for certain anime titles. The admin on MAL announced they would be overhauling the system to prevent said...

Dream: ...manipulation last week.
