The USA also has a site that seems to be up at the moment. Without seeing the CA version I'm not sure how it differs, but I suspect it's possible for Canadians to get some useful local information from it: https://www.tsunami.gov/

Anything that ends in .gov is related to a government entity in the US. Other countries don’t get access to that TLD.

ah, you're right. I knew that, think I must've looked at it too fast and assumed it was .gov.ca. (which isn't even the TLD that the Canadian government uses, but never mind...)

How big was the 2011 tsunami? Is 3m bigger or smaller?

It'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_an...

Is height the only thing that matters? Presumably 1x 2m wave is less impactful than 10 x 1m waves spread 20 seconds apart?

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…

Sadly we won’t hear from the partners of everyone whose manga didn’t successfully predict a real disaster in a month.

Has anyone heard how bad it was in Petropovlosk? USGS estimates "severe" shaking with the possibility of moderate to heavy damage and a chance of fatalities. They have had quite a swarm of quakes there over the last couple of weeks, including one that was M7+ around the 20th.

It's a very remote, very thinly populated area. The entire Kamchatka peninsula has under 300,000 people, who (statistically) have 1 km2 each.

Sure but a bunch of those people live in Petropavlovsk and surroundings

On Twitter, a search for Russia brings up some videos of pretty severe shaking

ca.gov is California, not Canada. But our funny-accented cousins can access useful information on the .gov as well (the entire west coast of Canada is under tsunami watch at the moment).

Yeah but for how much longer? It’s a fire sale on anything intellectual down there.

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). We'…

Don’t worry, if there’s one nation we can trust to have done the right thing, it’s Japan.

I honestly can’t tell if this is satire.
