OK, first impressions. This looks like a well-researched article, and the sources look like high quality scholarly material. I don't see hint of OR, copyvio or neutrality concerns. Article is stable. I'm not happy with the images situation: the map should be zoomed in far more so the red triangle doesn't cover half of North Island. Something like File:Kermadec Arc.jpg would probably help understand the situation. Have you considered File:Expl1831 - Flickr - NOAA Photo Library.jpg (from [1])? MOS: The Smithsonian and Te Ara external links should be in an "External links" section (or reused as references). Will comment on prose/broadness/focus below while doing section by section review. —Kusma (talk) 20:25, 21 April 2022 (UTC)[reply]

Did some of these things. Jo-Jo Eumerus (talk) 09:15, 22 April 2022 (UTC)[reply]
Improved! What I'm missing from a "broadness" point of view is perhaps why the volcano is called "Healy" (and maybe also when it was discovered). The obvious educated guess is that it was named after James Healy (this guy). The New Zealand Gazetteer renaming the feature to "James Healy Seamount" [2] (they say it was called "Healy Volcano" from 2006 to 2016) makes this look rather convincingly plausible. —Kusma (talk) 21:31, 22 April 2022 (UTC)[reply]
Found a source: [3]. "Discoverer: New Zealand research vessel "Tui". Year of discovery: 1965. History: Named after Dr James Healy, OBE (1910-1994) for his early research in New Zealand volcanology and geothermal exploration in the Wairakei region." Ship must be HMNZS Tui (T234). —Kusma (talk) 21:45, 22 April 2022 (UTC)[reply]
Added. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
OK. —Kusma (talk) 16:08, 23 April 2022 (UTC)[reply]

The images in the infobox need better captions. —Kusma (talk) 16:08, 23 April 2022 (UTC)[reply]

Done. Jo-Jo Eumerus (talk) 16:19, 23 April 2022 (UTC)[reply]

Content and prose review

[edit]
  • Lead: Will comment on whether everything is covered lates. Please do not use 590±80 years ago as that becomes wrong at a rate of 1 year per year.
    Replaced with "before present" (1950) which is the normal reference frame. Jo-Jo Eumerus (talk) 16:04, 22 April 2022 (UTC)[reply]
    Ah, defining "present" as a specific year makes some sense.
  • Parts of the "Loisels Pumice" in New Zealand is suspected are suspected, or change "parts" to "a part" or similar
    Done. Jo-Jo Eumerus (talk) 16:04, 22 April 2022 (UTC)[reply]
  • Regional: Colville Ridge is called Tonga Trench on Wikipedia and in the map?
    No, that's a completely different thing. Jo-Jo Eumerus (talk) 16:04, 22 April 2022 (UTC)[reply]
    My confusion is that you link to Colville Ridge, which redirects to Tonga Trench and I don't really know what it is.
    That's just redirects being confusing. Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
    No, it's not the redirects that are confusing, it is the links. My guess from combining your description with the map is that if I go eastwards from the "s" in "Brothers", I pass through the Kermadec Trench, Kermadec Ridge, Havre Trough and Colville Ridge. But both "Havre Trough" and "Colville Ridge" link to Tonga Trench, more than 1000km north (and that article doesn't define what "Havre Trough" or "Colville Ridge" are). So after clicking the links, I seriously doubt that my "guess" is correct. Looking at the gazetter again [4] [5], it seems the redirects are nonsense, as both features are between 30 and 35 degrees S. So perhaps the redirects should go elsewhere, or you should not link to them? —Kusma (talk) 16:08, 23 April 2022 (UTC)[reply]
    Perhaps the redirects should be deleted until the Tonga article gets that information added; I also thought of using Kermadec-Tonga subduction zone instead but that doesn't discuss them either. Jo-Jo Eumerus (talk) 16:19, 23 April 2022 (UTC)[reply]
    RFD'd, see Wikipedia:Redirects for discussion/Log/2022 April 23. —Kusma (talk) 17:03, 23 April 2022 (UTC)[reply]
  • There, the Pacific this "there" refers to Colville Ridge only?
    No, Kermadec Trench. Jo-Jo Eumerus (talk) 16:04, 22 April 2022 (UTC)[reply]
  • at the latitude of Healy.[3] giving rise Good to split the sentence, but perhaps start the second one "This gives rise"?
    Split. Jo-Jo Eumerus (talk) 16:04, 22 April 2022 (UTC)[reply]
    I tried to fix the grammar.
  • better studied than the rest of the arc not sure this is relevant here
    Well, this is the section where we discuss this arc segment. Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
  • I think it would help (in both "Local" and "Regional") to know how deep the sea floor is in this area. (you tell me how deep I need to dive to reach the top of the volcano, but not how tall the volcano itself is).
    The sources are pretty sparing on giving bathymetric figures. Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
    I found this: [6]. And it says the bathymetric map is PD :) —Kusma (talk) 21:03, 22 April 2022 (UTC)[reply]
    Hmm, I always thought that these files were under crown copyright. Anyhow, uploaded and added that one. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
  • The sentence describing the volcano consisting of Healy Caldera, Healy Edifice and Cotton Volcano is quite long; try to split? For example "... consisting of Healy Caldera, Healy Edifice and Cotton Volcano. Healy Caldera is ... Healy Edifice is ... Cotton Volcano is..."
    Rewritten. Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
  • Many duplinks (felsic, caldera, breccia and especially basalt).
  • Healy is part of a northwest-trending chain of volcanoes, which includes Giljanes, Yokosuka and Rapuhia This would be so much easier to understand with a decent map like in Wysoczanski et al... but probably not easy to get one.
    Aye, not easy to get uncopyrighted bathymetric maps. Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
  • most of the flanks are covered with ... rare outcrops I'm probably misunderstanding something, but are there only very few outcrops (in which case "outcrops are rare" would perhaps be easier to read) or is "rare outcrops" something specific like "outcrops consisting of rare earths"?
    Went with "rarely". Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
  • Composition: Healy volcano may feature ore deposits and has been considered a target for mineral prospecting. I don't see anything about ore deposits in the source (and it might be nice to say who has considered this). "
    Actually, it does: Although active SMS (seafloor massive sulfide)-forming processes are observed in widespread sulphide chimneys there is no accumulation at or near the surface of commercial quantity of sulphide mineralization in the areas drilled”, based on 23 core holes up to 14 m deep drilled in 2005. Their report identifies the calderas of Brothers and adjacent Healy submarine volcanoes as “drilling targets” Jo-Jo Eumerus (talk) 19:24, 22 April 2022 (UTC)[reply]
    Somehow I didn't read "sulphide mineralization" as "metal ores". OK so they drilled elsewhere and didn't find anything, but still have hopes for Healy? —Kusma (talk) 19:50, 22 April 2022 (UTC)[reply]
    Seems like (imma try this tool as well) Jo-Jo Eumerus (talk) 19:59, 22 April 2022 (UTC)[reply]
  • Healy is dominantly formed by rhyodacitic rocks but basalt also occurs, they define a low-potassium suite. I'm too non-geologist to understand what a "low-potassium suite" is, so I only have a grammar question: what does "they" refer to?
    Changed. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
  • although an origin through fractional crystallization is possible at Healy as the previous sentence said that, I don't understand why you contrast it with "although".
    Because it's not the favoured theory. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
  • Eruption history: A hydrophone data indicate Do you mean "Data from a hydrophone indicate"?
    Rewritten. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
  • Probably a good idea to unify the "last eruption 1360" in the infobox with the "590 BP" used in this section.
    Added a footnote. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
    Please double check your footnote, you have written "1360±75 years ago" where you probably mean "1360±75 CE". —Kusma (talk) 16:08, 23 April 2022 (UTC)[reply]
    Oop. Corrected that. Jo-Jo Eumerus (talk) 16:19, 23 April 2022 (UTC)[reply]
  • Loisels pumice: they might have been transported on land by tsunamis on land or onto land?
    Onto, I think. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]
  • Hazards: do we know anything about how low the risk is?
    No, that isn't known for most volcanoes. Jo-Jo Eumerus (talk) 13:27, 23 April 2022 (UTC)[reply]

Enough for today; I'll look again this weekend (more copyediting may be needed, but I'm too tired for that now). Hope you find my name and discovery-related finds in the section above useful. —Kusma (talk) 22:03, 22 April 2022 (UTC)[reply]

  • I think I'm happy now. The two redirects should either target something better or be turned into stubs, but that can be sorted out independent of what happes here. —Kusma (talk) 08:07, 24 April 2022 (UTC)[reply]

Name

[edit]

As noted above official name has now changed twice and since 2017 is James Healy Seamount see https://gazetteer.linz.govt.nz/place/56549 ChaseKiwi (talk) 22:10, 18 October 2022 (UTC)[reply]

@ChaseKiwi:It doesn't appear to be the most common name, though? Jo-Jo Eumerus (talk) 10:54, 19 October 2022 (UTC)[reply]
Indeed, but since a common name might be that assigned previously to a seamount near the north pole, it had to change. ChaseKiwi (talk) 16:46, 23 October 2022 (UTC)[reply]

Cotton Seamount Subsection

[edit]

Wondering weather it is worth adding a sub section for the Cotton Seamount witch is a part of the southern flank of Healy Seamount

as at the moment the cotton seamount links directly to this article without much explanation altho it is listed in local i think this could be more clear Rocketmannz (talk) 05:34, 7 April 2024 (UTC)[reply]

It seems like there is no information, period, on this seamount other than the name? Jo-Jo Eumerus (talk) 08:42, 7 April 2024 (UTC)[reply]
There is some more info about it on linz https://gazetteer.linz.govt.nz/place/55518 it has some references to some other publications it is mentioned in mainly a journal of volcanology would be interested to see what that has to say but even an explanation that it is a smaller volcano part of the larger Harley seamount would be good for charity 118.93.180.167 (talk) 09:22, 7 April 2024 (UTC)[reply]
As it turns out, Cotton was already mentioned in the article. Slightly expanded its mention. Jo-Jo Eumerus (talk) 09:39, 7 April 2024 (UTC)[reply]
Looks good Rocketmannz (talk) 09:58, 7 April 2024 (UTC)[reply]
