Nominator(s): Jo-Jo Eumerus (talk) 16:31, 12 April 2021 (UTC)[reply]

OK, the first nomination didn't work out but at least one editor who had raised concerns back then appears to have been satisfied by changes performed at Peer Review, so I am trying again. This article is about a rather unimpressive-looking volcano in Peru which in 1600 had a major eruption. This eruption devastated the surrounding region and caused worldwide climate change, including one of Russia's worst famines. Pinging participants of the PR, these mentioned there and of the previous FAC: @Gog the Mild, Iridescent, Femkemilene, ComplexRational, Fowler&fowler, MONGO, Ceranthor, SandyGeorgia, AhmadLX, Heartfox, Buidhe, and Z1720: Jo-Jo Eumerus (talk) 16:31, 12 April 2021 (UTC)[reply]

  • Notes: this is the lead. Its language should be accessible and explain the science easily. "Central Volcanic Zone" redirects to a section of the AVB, so no need to repeat. No need to explain either that the SA plate might have an oceanic half, but some clue should be given of its birth (without going into the convection in the mantle). More later. Good to see this. Fowler&fowler«Talk» 17:38, 12 April 2021 (UTC)[reply]
  • Seems like I missed one other issue ... " and by the former's molten contents being forced up" isn't really how the process works. The article does not discuss this but the main process is the release of fluids by the downgoing slab into the overlying mantle, which causes the latter to melt. Jo-Jo Eumerus (talk) 14:25, 13 April 2021 (UTC)[reply]
Second paragraph, lead
  • "During" has the meaning of "throughout," or "in the time of" and is more commonly applied to a time that has ended.
  • Better in my view: "In the Holecene ..."
  • Witnessed by people in the city of Arequipa,
  • Arequipa was established in 1540, and after 60 years, it was most likely still a colonial settlement.
  • Better in my view: the "town of" or "the settlement of" (later on we say "Arequipa Metropolitan Area" so people will know soon enough that it is a city now.)
I think that by contemporary definition it would be considered a "city". Jo-Jo Eumerus (talk) 09:32, 19 April 2021 (UTC)[reply]
  • This index was not around then and is quite likely based on historical reconstructions
  • Better in my view: this eruption has been computed to measure 6 on ..."
  • infrastructure a
  • "infrastructure" is a modern word (ca. 1920s or 30s), with its meaning these days including power-plants, highways, airports, ports, dams, railroad tracks and whatnot.
  • Better in view: "the foundations of buildings" (if that is what is meant; if not, perhaps you can explain a little more what is)
  • economic resources
  • This too is vague in the context of a relatively new colonial settlement.
  • Better in my view to mention the most salient resources by name.
  • The eruption had significant effects on Earth's climate; temperatures in the Northern Hemisphere decreased, and millions of tons of acid were deposited. Floods, famines and cold waves resulted in numerous places in Europe, Asia and the Americas. The climate disruption caused social upheaval in countries as far away as Russia and may have played a role in the onset of the Little Ice Age.
  • There are some coherence issues here: "millions of tons of acid," whose origin and effect are unexplained, appear in the middle of climate. Social upheavals appear between cold waves and the Little Ice Age.
  • Better in my view: The eruption had a significant impact on Earth's climate: temperatures in the Northern Hemisphere decreased; cold waves affected places in Europe, Asia and the Americas; and the climate disruption may have played a role in the onset of the Little Ice Age. Floods, famines, and social upheavals resulted.
  • (Note semi-colons are allowed in lists, especially ones with internal commas.) If the eruption really did have such an impact, then it is likely that floods, famines, and social upheavals were more widespread than in a few countries we are able to list. Also, this was a violent physical event; it is a situation for which we can–without stylistic worries–use the word "impact" in its figurative meaning.
Third paragraph, lead
  • Huaynaputina has not erupted since 1600. There are fumaroles in its amphitheatre, and hot springs occur in the region, some of which have been associated with Huaynaputina.
  • Probably better if second Huaynaputina ---> "this volcano." and "This volcano" in the following sentence ---> Huaynaputina
  • lies in a remote region, where there is little human activity.
  • Better in my view to make the clause restrictive: i.e. "lies in a remote region in which there is little human activity."
  • "Even so" is probably more precise than "still," or "Although H. lies in a remote region, there are ..." (but this is not a biggie; I use "still")
  • "Surrounding area" can mean "immediately surrounding area," which can be confusing; better in my view: there are about 30,000 people living in its proximity, and another 1 million ..."
  • If an eruption similar to the 1600 event occurred, it would likely lead to a high death toll and cause substantial socioeconomic disruption.
  • occurred--> were to occur
  • likely--> quite likely. (Your last volcano article was written in British/Commonwealth English which shuns the adverb "likely," a relatively recent Americanism, preferring "very likely." In this instance, the more modest "quite likely" is probably better. (Note: I tend to use only "likely" myself, though usually in informal situations.)
Done. Jo-Jo Eumerus (talk) 09:32, 19 April 2021 (UTC)[reply]

That's the lead. I hope I haven't made any typos. Fowler&fowler«Talk» 19:48, 18 April 2021 (UTC)[reply]

Source review

Okay fine.
  • "Huaynaputina lies at an elevation of about 4,850 metres (15,910 ft)." This is vague. Is its base at that elevation (as "lies" would suggest)? Or the highest point on the rim? Or the floor of the amphitheatre? Should be changed to something like "The summit of Huaynaputina lies at an elevation of about 4,850 metres (15,910 ft)."
    The source does not specify and none of the others I've seen discusses this aspect. I am guessing that the unusual morphology of the volcano makes it hard to assign it a height. Jo-Jo Eumerus (talk) 08:45, 23 April 2021 (UTC)[reply]
This one says "Summit Elevation 4850 m (15912 ft)".
Hmmm. That source does not explain how it comes to that conclusion and the last digit (0) makes me wonder if they are approximating. Jo-Jo Eumerus (talk) 20:52, 24 April 2021 (UTC)[reply]
It is the very source that you've used in the article to support the elevation thing.
Yes, but as I've said this volcano does not quite have a "summit" so I am wary of interpreting it as such. Jo-Jo Eumerus (talk) 09:47, 25 April 2021 (UTC)[reply]
Maybe something like "The event continued with earthquakes and ash fall for over/about two weeks and ended on 6 March."?
Yeah, that's better; implemented it. Jo-Jo Eumerus (talk) 09:03, 24 April 2021 (UTC)[reply]
  • "It has been proposed as a marker for the onset of the Anthropocene." Important term; short description.
    I admit, the source there does not bother to actually state an explicit definition of the term and its importance; it's more like several allusions. Do you have a proposed explanation? Jo-Jo Eumerus (talk) 09:03, 24 April 2021 (UTC)[reply]
I think the controversy regarding the exact starting point of the epoch is not relevant here. We can just brief that it is a period in Earth's history in which human impact on global climate has been considerable. This can be helpful.
I agree that the controversy doesn't matter, but even from the source currently used it doesn't seem like everybody defines it as "a period in Earth's history in which human impact on global climate has been considerable." Jo-Jo Eumerus (talk) 20:52, 24 April 2021 (UTC)[reply]
IMO, it is completely trivial. People scream in every disaster. There is nothing unusual about it to warrant a mention here. If people didn't scream and run around in such an event, that would be something of a note.
I am going to disagree on this one. I think that sentence helps underscore that this was an actual human tragedy rather than a statistical pattern. Jo-Jo Eumerus (talk) 20:52, 24 April 2021 (UTC)[reply]
@AhmadLX:Is there any other problem that needs addressing? Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • Although I believe that several of my concerns were dismissed through unconvincing arguments (both here and in PR), I, nonetheless, think that this now meets the criteria. so I support. AhmadLX-(Wikiposta) 15:27, 2 May 2021 (UTC)[reply]

Will take a look at this soon. Might claim for 5 points in the WikiCup. Hog Farm Talk 02:46, 30 April 2021 (UTC)[reply]

  • The Quechua name of Waynaputina from the infobox should be mentioned in the names section
    Removed it pending a source as I can't find anything endorsing that spelling. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • I'm not entirely for sure what the value of link to List of volcanoes in Peru in the infobox is
    For people who want to know more about Peruvian volcanoes? Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • Is the redirect El Misti the correct link in the context of " Other volcanoes in this zone from northwest to southeast include Sara Sara, Coropuna, Ampato, Sabancaya, El Misti, Ubinas, Ticsani, Tutupaca and Yucamane"?
    Yes, it's a common name for that volcano. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • "The event continued with earthquakes and ash fall for about two weeks[82] and ended on 6 March;[5] the air was clear of ash from the eruption on 2 April 1600 - is the " an error, or is it an unclosed quote?
    An error. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • "the Huayruro Project began in 2015 and aims to rediscover these towns" - Any update on this?
    Not that much, and what little there is is a bit too specific I think. It's more about the towns than the volcano. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • While the flora of the volcano is mentioned, fauna don't seem to be. Even if wildlife is not present on the volcano in significant numbers, I feel like that should be mentioned.
    The problem is that there is no source definitively discussing fauna in the context of Huaynaputina. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • The external link is dead and should be removed or archived. If it doesn't add anything significant, just remove it.
    Removed it. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • I didn't see where the 500,000 age of rock figure from the infobox appears in the body; I may have missed it.
    It's not based on anything, just typical infobox OR. I've removed it. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
  • Not all of the non-English sources state which language they are in; this should be added for all non-English sources.
    Done. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]

That's it from me, I think. Hog Farm Talk 21:58, 1 May 2021 (UTC)[reply]

@Hog Farm:Replied to queries. Jo-Jo Eumerus (talk) 10:31, 2 May 2021 (UTC)[reply]
Supporting on WP:FACR #1a, 1b, 1d, 1e, 2a, 2b, 2c, and 4, with the understanding that the article will be updated in the future if studies on fauna on the volcano are performed. Did not check other criteria. Hog Farm Talk 17:39, 2 May 2021 (UTC)[reply]

That takes me to the Geology section. The biggest concern here is the jargon and also not mad keen on all the crowbarred references. More to come. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 20:19, 18 May 2021 (UTC)[reply]

Did these things. If I may, I'd like to ask that the current reference style stay until everybody has got a chance to review the content - as mentioned before, grouped references make it harder to solve a content issue. Jo-Jo Eumerus (talk) 09:19, 19 May 2021 (UTC)[reply]

That takes me to "Eruption history". Generally this section is for all intents and purposes inaccessible to anyone without some level of expert knowledge in volcanology. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 15:15, 20 May 2021 (UTC)[reply]

It should be clearer now I think, but the detailed geology and in particular composition are really only of interest to people who know at least some concepts. Jo-Jo Eumerus (talk) 17:10, 20 May 2021 (UTC)[reply]
I fixed it. Volcanoguy 22:13, 21 May 2021 (UTC)[reply]

Up to "1600 eruption" section. More to come. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 11:37, 21 May 2021 (UTC)[reply]

That takes me to the "Local impact" section. More to come. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 12:34, 23 May 2021 (UTC)[reply]

That takes me to "Climate impacts", more to come. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 20:21, 24 May 2021 (UTC)[reply]

Just the refs remaining on this first pass now. The Rambling Man (Stay alert! Control the virus! Save lives!!!!) 09:28, 25 May 2021 (UTC)[reply]

@The Rambling Man:OK, I totally missed these comments. I'll do these now... Jo-Jo Eumerus (talk) 14:17, 29 May 2021 (UTC)[reply]
