Japan forecasting tsunamis up to 3m across basically the entire eastern coast. First waves will hit within 10 minutes.

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). We're about to find out the hard way what lessons they have learned.
Update: First detected wave in Nemuro, Hokkaido (northernmost Japan) was only 30cm. There may be more. Waves of 3-4m have apparently already hit Kamchatka in Russia.
Update 2: We're almost an hour in and highest waves to actually hit Japan remain only 40 cm. It looks unlikely that this will cause major damage.

- Brystephor 1y agoHow big was the 2011 tsunami? Is 3m bigger or smaller?
- decimalenough 1y agoIt's complicated. Tsunami forecasting is a very inexact science and "3m" means "very large". The average actual height in eastern Japan (Tohoku) was 4-6m, but there were peaks up to 20m in places like Ofunato where the local geography funneled all the water upwards. https://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_and_tsunami#Tsunami https://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_an...
- timr 1y agoFor perspective, the tsunami that topped the seawall at Fukushima Dai-ichi had a peak height of ~14m. The seawall was 5.7m.
- hsbauauvhabzb 1y agoIs height the only thing that matters? Presumably 1x 2m wave is less impactful than 10 x 1m waves spread 20 seconds apart?
- edoceo 1y agoVelocity of wave as well.
- brewdad 1y agoDepends on topography and protections in place. 10 1m waves against a sound 1.5m seawall is no big deal. 1 2m wave against the same seawall could be a problem.
- idontwantthis 1y agoA tsunami is a gigantically long wave. I don’t think what you’re describing describes a tsunami.
- leptons 1y agoThat is not really a good description of a tsunami. Tsunamis can occur in very narrow areas too, like when landslides happen in fjords.
- shusaku 1y agoMy guess is that the wide area simply reflects the uncertainty, and not some apocalyptic scenario. Hopefully this broad warning and plenty of time gets everyone out of danger effectively
- deadbabe 1y agoDon’t worry, if there’s one nation we can trust to have done the right thing, it’s Japan.
- mulmen 1y agoI honestly can’t tell if this is satire.
- decimalenough 1y agoSame. Japan's earthquake/tsunami preparedness is genuinely unmatched, but earthquakes/tsunamis have the annoying habit of happening in the "wrong" place and the country's overall record of "doing the right thing" can charitably be described as spotty.
- sugarpimpdorsey 1y agoJapanese news reporting during disaster scenarios is something to behold. The screen is filled with data and blinking like a Bloomberg Terminal.
- username135 1y agoPachinko!
- pezezin 1y agoTo 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
- gibagger 1y agohaha, 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.
- socalgal2 1y ago> Funny thing is how for interior design they do a full 180 and typically go very minimalistic. Only if they are well to do. Most family houses in Japan are crammed full of stuff with very little "design".
- ccozan 1y agoI 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 saw in this video[0] that the first waves had arrived, and assumed the heights would've therefore corresponded to actual measurements. But it's still in the "predictions" section, and I should've noticed that before posting....) [0] https://www.youtube.com/watch?v=YbRCvDZO5Zk https://www.youtube.com/watch?v=YbRCvDZO5Zk
- timr 1y agoNo. That's the predictions. Biggest wave so far has been 60cm (EDIT: as of 6am UTC it's 1m30cm, but that's still relatively small. It came up almost exactly to the top of the pier in Kuji.)
- BalinKing 1y agoI've updated my comment, I indeed misunderstood what I read.... Unfortunately it's too late for me to delete the comment, so everyone please feel free to flag/downvote it (both to push it down for the sake of clutter, and also to punish my carelessness :-P).
- timr 1y agoNo worries -- the way they present it is confusing, particularly if you're watching the NHK World stream, which layers poorly translated English versions on top of the Japanese.

- carabiner 1y agoI've been monitoring the situation, but it appears nothing ever happens.
- ashoeafoot 1y agoQuestion: Could you cancel out a tsunami with a underwater explosion, similar to active noise canceling ?
- kstrauser 1y agoYes, 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.
