A tsunami absolutely does not fit our intuition of what waves are. It looks like a wave. But it does not stop. It just continues. That little wave goes on an on, farther and farther inland. After an hour it may still go on. It's a nightmare wave, because it doesn't not fit one's intuition of what waves are.

>It looks like a wave. and it IS a wave. I don't understand the resistance here. It BOTH is a wave and looks like a wave. But because it does not stop, it is not a "wave". Let's just stop with the strange pedantism.

I'm reacting against the word "intuition" here. Nobody said it isn't a wave. But it's not like a wave as our intuition says.

(Though it does not _always_ look like a wave - check out the timelapse video from Kuji harbor: https://www.youtube.com/watch?v=M1B1J6sgFxk - that's why you'll sometimes see people talking about it looking like a (very) high tide. As an example of the nightmare "wave" which doesn't stop, and is thus un-intuitive.. https://www.youtube.com/watch?v=3618dZoiaPE which is incidentally also from Kuji, but from 2011)

I know what you’re talking about. But intuitively it’s still a wave.

Oh yes! It’s absolutely true that underwater geography can steepen the wave front and amplify the height, sometimes by orders of magnitude. The deep water height of a tsunami wave is often a lot different from what you will see at the coastline. An entertaining anecdote from the pre- smartphone era: I sailed to the site near Chenega bay where the earthquake wiped out the village in 1958. We got permission from the el…

> Interestingly, there are big tidal bores frequently in Turnagain arm, with 1-3m being common. I’ve seen people surfing it with wetsuits in the ice cold water, getting a run of several miles lol. That’s going on the bucket list! How dangerous is it? If you biff it and get caught by the wave can you just dive under the wavefront and come up behind it like on a beach?

I don’t know much about the dangers involved, but it isn’t (or wasn’t, AFAIK) a big attraction… so maybe it’s crazy or dangerous? I’m not sure. Or it might be because the water is so cold that hypothermia and death is inevitable in less than an hour? Or because there probably is no realistic chance of rescue if something goes wrong?

At any rate, there was enough people willing to try that I saw it a couple of times, and TBF I think windsurfing isn’t too unusual in the arm now. But there is also trees and stuff in the tidal bores sometimes, so maybe debris is a big problem or the area is too shallow to be safe.

But, if it’s doable, I’m sure it would be memorable!

That's because the other mangas forgot to adjust by +/- some 1000 km for location, 25 days, 365 days, 1825 days, or some other arbitrary but possibly nicely divisible number, for when and where it strikes. You also have to conveniently forget the things that don't sell mangas such as annual typhoons, heatwaves, and of course thousands of premature deaths from man-made causes such as pollution and poor lifestyle. Othe…

Reminded of the available $1m award from James Randi’s org that was never claimed b/c no one could ever do anything supernatural under reasonable testing conditions. (Woo is surely possible but all those who can pull it off were gifted abilities that are deactivated by non-monetary incentives)

I do live in Japan and good god, I have never seen such messy people anywhere else in the world. The offices of all my Japanese colleagues are piles upon piles of documents and boxes without any kind of order. But the cities themselves are like that. There is zero urban planning, just buildings thrown around in impossible non-Euclidean patterns.

They're a book from the early 1990s called "Tokyo Style" that is packed with photos of real living conditions from back then. Chaos of every variety. Plus some Super Famicom and PC-Engines laying around. A very cool book, most recently reprinted in 2024 with Japanese/English captions.

Here's the full book "Tokyo: a certain style" by Kyoichi Tsuzuki (same author), https://archive.org/details/tokyo-a-certain-style

I believe that's essentially the first English edition.
