A tsunami is a gigantically long wave. I don’t think what you’re describing describes a tsunami.

That is not really a good description of a tsunami. Tsunamis can occur in very narrow areas too, like when landslides happen in fjords.

I mean long as in wavelength. You wouldn’t have a series of tsunami waves.

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).

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

Pachinko!

> That's interesting. Mental note, if piloting a vessel in a tsunami, head to deep water. E.g. the 2011 tsunami may have had a height of 1.2m or so in open ocean, but when concentrated by shallower water and a bay inlet reached 40m .

Here's a visual of your thoughts from the Fukushima event: https://m.youtube.com/watch?v=-VcWF8dIDj4 Japan, Tsunami. Coast Guard ship rides over the tsunami waves. 日本 - 津波 4.1M views · 14 years ago

Neat video. It seems to capture the middle between "super high coastal wave" and "shallow but long duration wave in deep water". That's what you'd get with coastal waters several tens of meters deep.

> The statement was revised later to specify the date "July 5, 2025" as that of an asteroid impact,[8] or even the end of the world.[9]

Ryo Tatsuki clarified it wasn't her that said July 5th was when the big one will hit but that it was her publisher that pushed that date for marketing and sales. She along with the Thai clairvoyant and Brandon Biggs all say July is the month when the earthquakes and tsunamis begin . It is unwise to simply write this off, Ryo Tatsuki said she saw 4:18am in July 2025 which can only mean 14 hours from now we will know i…

This article states that that the book references the 5th day: https://www.newsweekjapan.jp/akane_t/2025/05/202575jaxa.php

Is it wrong? Did the book actually just call the time and month, not day?

Air alarms are going off in Hawaii. Still a few hours away, but they are not joking around. Saying it can wrap around all the islands and hit anywhere

Phone just went off screaming with a warning here in NZ - more a "stay away from the water" warning than a "head for the hills" one

Impressive, glad the alarm chain works. And from what you say the warning message is also clear and understandable. Not tech or geology jargon that people don't understand and then take no or the wrong actions.

I've been monitoring the situation, but it appears nothing ever happens.

Shanghai has relocated 280.000 people from its coast according to this article: https://mp.weixin.qq.com/s/HLf3PM29IqaWajMhflo_uA Unclear if its related to the tsunami that is about to hit or the typhoon it is currently experiencing. Wild. Stay safe everyone!

Update: The yellow warning has been lifted
