In the geology section there is a two leaf map labeled, "Mechanism of 2011 Tohoku earthquake" Both panels make reference to "the North American Plate" sitting adjacent to this geographical section of Japan. I believe this is grossly incorrect, Japan does not sit on any piece of the North American Plate. Both map panels need serious revision. Astrophysicalchemist (talk) 13:11, 19 June 2023 (UTC)
I agree that it probably should have been labelled as the okhotsk microplate, however I don't think there is a consensus on whether it is fully its own thing. If someone has a similar graphic with better labelling then I would support its replacement, but I don't see the need for the current image's removal at the moment Vreee (talk) 01:11, 12 March 2024 (UTC)

it isn’t the fourth most powerful earthquake, its number 6 most powerful ever recorded. Timplin (talk) 19:38, 11 March 2024 (UTC)
Not done: The article says it was the "fourth most powerful earthquake recorded in the world since modern seismography began in 1900" - this is correct, 2 of the more powerful quakes happened before this. Jamedeus (talk) 19:45, 11 March 2024 (UTC)
299%g should be XI, not VIII

I was quite shocked when I saw VIII here along with 2.99g of PGA. USGS Estimations state that PGAs that exceed 1.39g should be considered as X-XII. So a rough estimate of it would be around XI-XII. Waitwott (talk) 07:52, 13 April 2024 (UTC)
Furthermore, the Ishikawa earthquake had 2.88 g of PGA, yet it is considered X-XI. So how come did 3.11 have VIII even with nearly 3g of acceleration? And also, please separate the intensities to their respective blocks, instead of putting its counterpart in parentheses/brackets. Waitwott (talk) 07:58, 13 April 2024 (UTC)
The Ishikawa earthquake intensity was supported by a source [1]. The VIII intensity in this article is supported by the USGS event page impact summary. I haven't come across any credible source that suggests a different maximum Mercalli intensity. Interpreting the 2.99 g PGA would constitute WP:SYNTH.

Change "It lasted six minutes, causing a tsunami" to "It lasted six minutes and caused a tsunami." The former implies the length of time or severity of shaking caused the tsunami, but tsunamis are simply caused by the displacement of a large volume of water, regardless of how strong or long the shaking was. 2601:1C0:4D7C:6C00:DDF8:6226:A9B1:CB56 (talk) 03:48, 16 May 2024 (UTC)
Done The two aren't completely unrelated - length of shaking relates to size of rupture, which relates to the amount of water displaced but I take your point, thanks. Mikenorton (talk) 08:57, 16 May 2024 (UTC)
