Lede

[edit]
  • For the first sentence, add volcanic before La Palma, since you go on to compare this to other volcanic islands.
    "volcanic La Palma" implies that there is such a thing as non-volcanic La Palma. There isn't, so I wouldn't use that term. Jo-Jo Eumerus (talk) 18:41, 21 September 2020 (UTC)[reply]
  • Since this article is only about Cumbre Vieja, the last sentence - "Other volcanoes across the world are also at risk of causing such tsunamis." is unnecessary unless you wish to write an article about all the tsunami threats around the world.
    That's mostly additional info. The Cumbre Vieja hypothesis has informed research on similar dangers elsewhere. Jo-Jo Eumerus (talk) 18:41, 21 September 2020 (UTC)[reply]
  • You need to incorporate what you just said into the article. You need to say in the lede how the the Cumbre Veija research affected research of other volcanoes. ~ Destroyeraa🌀 19:25, 21 September 2020 (UTC)[reply]
  • Then I don't get why you are including so many examples of other volcanoes/earthquakes and tsunami threats if they don't (in some way) relate to this article and this subject. ~ Destroyeraa🌀 15:51, 22 September 2020 (UTC)[reply]

Sector collapses and tsunamis caused by them

[edit]
  • In this section, you mainly explained about Volcano collapses and tsunamis caused by them. However, you didn't mention much about Cumbre Vieja except in the second paragraph. You go on to list a bunch of earthquakes and tsunamis around the world. Remember what the title of the article is - Cumbre Vieja tsunami hazard. You may want to shorten this section so you don't take away much from the subject.
    Well, the article is principally about the hypothesis of a tsunami, so giving a bit more consideration to that aspect is warranted. Jo-Jo Eumerus (talk) 18:41, 21 September 2020 (UTC)[reply]

OK. Carrying on...

@Destroyeraa:Just a note, editing a ping into an already existing post doesn't work. I am not sure how to make the text any clearer about the fact that it's about a timespan. Jo-Jo Eumerus (talk) 16:32, 30 September 2020 (UTC)[reply]
@Jo-Jo Eumerus: Add a note explaining what 87,000±8,000 means. ~ Destroyeraa🌀 16:34, 30 September 2020 (UTC)[reply]
Added one but I am dubious about its usefulness. Jo-Jo Eumerus (talk) 18:02, 30 September 2020 (UTC)[reply]

Tsunami hazards

[edit]
  • I am a bit confused of what might generate the landslide, which will in turn generate the tsunami. You list both volcanoes and earthquakes. Is it both, or is it just one.
    Both can do it. Jo-Jo Eumerus (talk) 18:02, 30 September 2020 (UTC)[reply]
  • You might want to fit this section with the "Potential impacts" section, since both talk about tsunami hazards. Especially the second paragraph in this subsection.
    I don't think that would make sense, as neither section goes into detail of what the impact of a tsunami on land is. Jo-Jo Eumerus (talk) 18:02, 30 September 2020 (UTC)[reply]
  • You do say what some of the hazards say in the second paragraph. I still highly suggest you merge some of the paragraphs with the Potential Impacts section. ~ Destroyeraa🌀 21:14, 5 October 2020 (UTC)[reply]
  • Overall nothing much that needs fixing (grammar, etc.) in this subsection.

Regional Context: Cumbre Vieja and the Atlantic Ocean

[edit]
  • "It is the fastest growing volcano in the archipelago and thus dangerous in terms of collapses and landslides." Why is it dangerous?
    Fast-growing volcanoes tend to become top-heavy and unstable. Sources do not spell this out, seems like. Jo-Jo Eumerus (talk) 18:41, 21 September 2020 (UTC)[reply]

Models

[edit]

Ward and Day

[edit]
  • "In light of the behaviour of other documented sector collapses such as at Mount St. Helens, the headscarp of the unstable part of Cumbre Vieja is likely 2–3 kilometres (1.2–1.9 mi) east from the 1949 fault and the toe of the sector lies at 1–3 kilometres (0.62–1.86 mi) depth below sea level; this latter reconstruction is supported by bathymetric observations west of La Palma." This sentence is rather long, I suggest you remove "such as Mount St. Helens," to improve the flow of the sentence.
    Split. Jo-Jo Eumerus (talk) 21:10, 14 October 2020 (UTC)[reply]
  • What does "566,000 Cumbre Nueva landslide" mean?
    Specified. Jo-Jo Eumerus (talk) 21:10, 14 October 2020 (UTC)[reply]
  • A scenario of a collapse of 500 cubic kilometres (120 cu mi) that moves at a rate of about 100 metres per second (330 ft/s) on top of a layer of mud or landslide breccia, which lubricate its movement, and eventually spreads 60 kilometres (37 mi) to cover a jug-shaped area of 3,500 square kilometres (1,400 sq mi)... doesn't sound like a complete sentence.
    Yeah, amended. Jo-Jo Eumerus (talk) 21:10, 14 October 2020 (UTC)[reply]

Other models

[edit]

Overall, this section is well written

Criticism

[edit]

Probability

[edit]

Potential impact

[edit]

I suggest you merge these short paragraphs with the "Tsunami hazards" subsection, since the tsunami hazards section needs more relation to the subject, which is Cumbre Vieja. Currently, this section is a bit too short.

Other volcanoes with such threats

[edit]

Remember, this is about the threat to Cumbre Vieja, if you want to turn this into a "see also" section, there needs to be links to the other tsunami hazard pages.

There aren't such articles, this is more a contextual section. Jo-Jo Eumerus (talk) 21:10, 14 October 2020 (UTC)[reply]

References

[edit]

References look good.

Overall

[edit]

Overall, a well-written article that is very close to GA class, though some parts may be confusing to the reader. I'm sorry for taking so long on this review, Jo-Jo Eumerus. ~ Destroyeraa🌀 19:48, 12 October 2020 (UTC)[reply]

@Jo-Jo Eumerus: Very well. I'm rather surprised the models have little information about the actual impact, though if you find more information, I'm sure you'll add it. Thanks, and good job. ~ Destroyeraa🌀 00:28, 22 October 2020 (UTC)[reply]

Other volcanoes with such threats

[edit]

Overall, it is a bit unclear what this article is about. Is it to list and explain the different tsunami hazards in the world, or is it to explain the Cumbre Vieja tsunami hazard? If the subject is the former, then the article needs to be moved accordingly to the correct title and be less about the Cumbre Vieja. If the subject is the latter, then it needs to be clearer to the reader that the subject is the Cumbre Vieja volcano and threat.

The article is principally about Cumbre Vieja; some of the other information is mostly context. Jo-Jo Eumerus (talk) 18:41, 21 September 2020 (UTC)[reply]

Reliable source?

[edit]

Is this a good source? The title is a little worrisome (Chicxulub is probably not the largest asteroid to hit Earth, the one that created the Vredefort crater would be and of course Theia). Jo-Jo Eumerus (talk) 20:18, 25 September 2020 (UTC)[reply]

@Jo-Jo Eumerus: I still don't understand how asteroids have to do with Cumbre Vieja. ~ Destroyeraa🌀 13:41, 29 September 2020 (UTC)[reply]
Little, but the source discusses the tsunami because it is about non-earthquake tsunamis. Jo-Jo Eumerus (talk) 15:49, 29 September 2020 (UTC)[reply]

Tsunami deposits?

[edit]

Please look for scientific journals analyzing any evidence for tsunami deposits of the coast of SC, USA for example—or lack thereof. 142.116.123.215 (talk) 01:03, 20 September 2021 (UTC)[reply]

I didn't find any source that explicitly linked any tsunami deposit there to Cumbre Vieja or other Canary Islands volcanoes. Jo-Jo Eumerus (talk) 07:19, 20 September 2021 (UTC)[reply]

Due weight on risk

[edit]

So, I know that this page doesn't have a lot of watchers but I'd like to have some discussion about whether the article gives too much weight to the worst-case scenarios. I've rewritten the lead a little to emphasize how unlikely a tsunami is but I don't know if it's enough.

The problem I think is that much of the risk discussion takes place via blogs and social media (which aren't good sources) and it often assumes that we all live in the USA (i.e it disregards the impact a collapse could have on the Canary Islands). Jo-Jo Eumerus (talk) 08:20, 20 September 2021 (UTC)[reply]

Location map

[edit]

I think an additional illustration with a location map showing where in the Altantic Ocean La Palma/Canary Island is located might be useful for readers who might not know where the Canary Islands are located as well as giving readers an idea of the impact.

The article itself doesn't explain where it's located and relevant location maps are currently found only on the La Palma and Canary Islands articles (I personally prefer the one on the Canary Islands article).

I'd add one myself, but I have no idea on how to add a location map.

I've added one, but it doesn't work properly. Jo-Jo Eumerus (talk) 13:24, 14 October 2021 (UTC)[reply]
Thank you! 193.183.211.65 (talk) 16:04, 15 October 2021 (UTC)[reply]

Coimbra or Porto

[edit]

So, this edit with the summary The referenced paper doesn't mention Coimbra, which is not a coastal town, so it has a very low probability of being affected by the tsunami. The paper, however, mentions Porto, which is a coastal city.. Now, from reading the source it actually says Coimbra, but I don't know whether to revert because that's not a coastal city. Jo-Jo Eumerus (talk) 11:51, 19 October 2021 (UTC)[reply]

"Fake news" source

[edit]

I can't speak Portuguese, but this source may be appropriate to use here. Jo-Jo Eumerus (talk) 17:26, 1 November 2022 (UTC)[reply]

More sources on social media

[edit]

doi:10.1016/j.ijdrr.2023.103694 might be worth mentioning in re social media during the 2021 eruption. Jo-Jo Eumerus (talk) 10:55, 7 December 2023 (UTC)[reply]
