Text and/or other creative content from this version of 2011 Tōhoku earthquake and tsunami was copied or moved into Aftermath of the 2011 Tōhoku earthquake and tsunami with this edit on 07:45 1 April 2011. The former page's history now serves to provide attribution for that content in the latter page, and it must not be deleted as long as the latter page exists.

On 11 March 2011, it was proposed that this article be moved to 2011 Tōhoku earthquake and tsunami. The result of the discussion was 'Moved' (see discussion; reason was "After long discussions, the German Wikipedia decided to change the name from "Sendai earthquake" to "Tōhoku earthquake", because the official name in Japanese refers to the region Tōhoku (Northeast). Sendai is a large city in that region, but not the city closest to the center of the quake. In addition, the city Sendai was not affected as severely as many other cities, particularly those affected by the tsunami.").

Wonky image problem[edit]

Testing here:

Lack of fuel caused the Fukushima Daiichi Nulcear Disaster?[edit]

The article currently (2023.11.3) states:

"The tsunami caused the Fukushima Daiichi nuclear disaster, primarily the meltdowns of three of its reactors, the discharge of radioactive water in Fukushima and the associated evacuation zones affecting hundreds of thousands of residents.[47][48] Many electrical generators ran out of fuel. The loss of electrical power halted cooling systems, causing heat to build up."

Say what? Is it not well accepted that the generators failed due to the damage caused from the tsunami, not due to their running out of fuel, or inability to refuel them. I can find thousands of references to the tsunami damage, not a single reference to lack of fuel. Can this claim be supported? — Preceding unsigned comment added by 118.243.166.151 (talk) 23:58, 10 March 2023 (UTC)[reply]

Geology Map[edit]

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)[reply]

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)[reply]

it isn’t the fourth most powerful earthquake, its number 6 most powerful ever recorded. Timplin (talk) 19:38, 11 March 2024 (UTC)[reply]

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)[reply]

299%g should be XI, not VIII[edit]

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)[reply]

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)[reply]

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.
