My wife decided to not travel to Japan due to an impending warning from a manga for July 2025. I have been making fun of her all month only to get this tsunami warning now! https://en.wikipedia.org/wiki/July_2025_Japan_megaquake_prop... . > The 2021 reprint capitalizing off this revived popularity warned of a "real disaster" in July 2025, causing a minor case of mass hysteria in 2025 when summer trips to Japan from E…

Is your wife generally fearful like that or this was a rare occurrence and she can actually have some introspection on that and has a fighting chance of coming on top of that?

I know few folks like that, for them it comes from general lack of understanding of reality, society and human nature, a lot of superstition in various directions and similar traits. Suffice to say its very hard to live up to one's potential in life with such mindset, but such things could be conquered if there is enough resolve.

I was parked at Selzer beach in Seaside, Oregon when the earthquake/tsunami news hit around 7:30pm. Within 30 minutes it was impossible to buy gas without queueing and now there is a pretty steady stream of cars heading out of town. As of 9pm it’s been upgraded to a warning up and down the coast. I was just thinking of tsunamis the two days ago in the Del Rey beach parking lot, where I noticed the locals seemed to pa…

I’ve never thought about a tsunami when visiting the beach in my life. Are they much more common in the Pacific? We go to the Gulf and Atlantic and it’s never something I think about. We usually go in June/July, so we don’t worry much about hurricanes either.

There is no Atlantic ring of fire, is there. What little places like Iceland show is nothing compared to what pacific has to offer in much larger area.

That is _really_ big. It will likely crack the top 8 ever recorded. https://en.wikipedia.org/wiki/Lists_of_earthquakes

The 1960 Valdivia quake released about 1.5e23 J, or about 1000 hurricanes, or about 25% of the total energy of all earthquakes in the past 100 years.

Japanese news reporting during disaster scenarios is something to behold. The screen is filled with data and blinking like a Bloomberg Terminal.

Also when you visit most japanese websites you can see this phenomenon. I've read an explanation once that this is because culturally, japanese people perceive a wealth of information and choice as being re-assuring and trustworthy, while most westerners feel more re-assured by seeing less content and choice presented in a more minimalist kind of way.

I actually prefer content style of Japanese websites. I get all the relevant info on one screen instead of having to scroll/click thru tens. The western style websites are very inefficient and hide info (feels scammy with lack of info).

To be fair, most of Japanese TV is like that. I always joke that the primary reason they developed HD TV was to be able to cram more text in every corner xD

haha, makes a lot of sense!. But then again, take a stroll around a shop-laden street in Japan and you'll see the exact same thing. They just like it that way. Funny thing is how for interior design they do a full 180 and typically go very minimalistic.

"content is beautiful"

While the Atlantic doesn't really have many faults that will generate earthquakes causing tsunamis there is always a risk of landslides creating large tsunamis up to what we'd consider mega-tsunamis. This said this is something that may have thousands of years between incidents.

Japan forecasting tsunamis up to 3m across basically the entire eastern coast. First waves will hit within 10 minutes. https://www.nhk.or.jp/kishou-saigai/tsunami/ https://www3.nhk.or.jp/news/live/ (live, Japanese) https://www3.nhk.or.jp/nhkworld/en/live/ (live, English) The east coast is also where the vast majority of Japan's population lives, and was previously hit by the 2011 tsunami (Fukushima and all that).

Question: Could you cancel out a tsunami with a underwater explosion, similar to active noise canceling ?

I was wondered that. Like from movies or documentaries, etc. Very nice, clear, order, minimalistic. Then I was looking to buy a house and I found a site with "almost" abandoned house for sale. My God. Everything , everywhre, no design ( haha ), no exceptions. People were actually living there. Had a cultural shock.

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.

Yes, but it would have to be equal and opposite the incoming tsunami, and the amount of energy involved is mind boggling. The recoil would have its own repercussions. Your neighbors on the receiving end of the resulting double tsunami would want to have a word with you.

I'm surprised so many people don't understand what tsunamis are. It's a "wave" created by a sudden shift in the Earth's crust. Imagine, suddenly, water on each of side of that split is now at different heights and has to equalize. It's much closer to just removing a dam that is holding back water equal in height to the new difference between the sea floors. What you get is not a "wave" but a wall of water.

This doesn't make sense to me intuitively. It must be a wave. Imagine you have a fault line. There is a left side and a right side to the fault line. If the left side lowers with a shift then that shift MUST be localized to the area around the fault. Because if it wasn't then that means there's an elevation change across the board for everything to the left of the fault. You see how that doesn't make sense? So if the…

Tsunamis are waves the same way a step function is the sum of a series of waves.
