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

My 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

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

Makes sense. More cushion for the pushin.

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.

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.

Severo-Kurilsk, an island town destroyed by a similar tsunami in 1956, lost its port again: https://en.wikipedia.org/wiki/Severo-Kurilsk — the rest of the settlement was rebuilt on higher ground, leaving only the port vulnerable.

The settlement is notable as having belonged to the Japanese in late 19th and early 20th centuries, who once relocated islanders there. Russian Wikipedia says they were Ainu.
