https://www.conservation.ca.gov/cgs/tsunami/maps is getting a hug of death :( If anyone gets on, please post a screenshot.

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/

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).

Can the wave be seen and tracked from planes above? I know they can travel at upwards of 300+mph but given the distance from Russia to the west coast seems like it should be able to be tracked.

No. When they travel at that speed they are not visible. Only when they hit shallow water (a necessary , but not sufficient, condition) do they slow down and become a threat.

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.

So far the news here has only shown damage to a school (which apparently was empty due to repair work), and some bad flooding in one part. Let’s hope for the best.

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

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

I think it has been revised to 8. Earth is going off today. Edit my mistake, 8.8 now!

The other way around it seems, on `07-29-2025 23:24:56 UTC` went from 8 to 8.7 [1]

USGS still has it listed as magnitude 8.7.

(Update: It was just revised upward to 8.8.)

Looks like it was just updated to 8.8?
