Homework by the uninterested adolescent replaced.
In tracing the origin of the four paragraphs describing an old but historical eruption on Mauna Loa I see it was added anonymously underb "punctuation repair" I can find no reference in the text provided to what volcano is being described, and there was no eruption of Mauna Loa in 1840 (year that the Wilkes expedition climbed the mountain, I believe). So I'm deleting the text as probably plagerized or made up and not relevent to Mauna Loa.Marshman 00:15, 2 Aug 2003 (UTC)
The inflation has been intermittent, sometimes stopping for several weeks, and although its rate has slowed at times it has not stopped and is likely to indicate an increased probability of an eruption in the next few years.
Well? Has it stopped or hasn't it? —Keenan Pepper 04:21, 11 July 2006 (UTC)
Also, a citation for that "next few years" claim would be nice. —Keenan Pepper 04:21, 11 July 2006 (UTC)
In the article about Mauna Kea "Mauna Kea is also the tallest mountain in the world when measured from base to peak" whereas in this article it is saying that Mauna Loa is... I have been told many times, including from my Geography Teacher who seems to have a very good knowlege of volcanic features says that Mouna Loa is the highest [although I haven't posed the question to her I just remember her telling the class that Mauna Loa was the higher than Everest and that from its base it was the highest land feature...]

Can we semi-protect this article for a couple of weeks? I just fixed multiple vandalisations that weren't caught by other editors --- it's a shame for a featured article to be so vandalised that garbage can persist for weeks and no one notice. hike395 05:16, 19 December 2006 (UTC)

I added some info about this eruption, which actually saw the US Army Air Corps attempting to divert the flow of lava from Hilo with aerial bombs. Anynobody 07:57, 5 August 2007 (UTC)
The article is correctly using English spellings of Hawaiian words. It should stay that way. There is no need to use Hawaiian spellings. So I edited the few inconsistent uses of 'a'a, etc., by removing the apostrophes and macrons, as they do not belong in English spelling. Since the article has nothing at all to do with Hawaiian language, there is no conceivable relevance for the use of any Hawaiian spellings. The sole exception is the explanation that mauna loa means "long mountain" in Hawaiian. And that was correctly done, italicizing the Hawaiian forms (which happen to have no glottal stops or long vowels in the Hawaiian spellings). Two-word place names, like Mauna Loa, use uppercase for both word-initial letters. So I edited "Ho'okena mauka" to "Hookena Mauka". In Hawaiian, Uka would be expected rather than Mauka, as in Ho`okena Uka (like in Kalihi Kai, Kalihi Waena, Kalihi Uka). The form Hoopuloa (or even Ho`opuloa) looks a bit odd as a Hawaiian place name. Perhaps someone can double check that name. Agent X 19:58, 19 July 2006 (UTC)
1. In opposition, "to use whatever is most commonly used", rather than using proper, established, nativized (i.e., Anglicized) spellings of loanwords, does not make sense at all. Consider the English loanword sushi, from Japanese. The word is "most commonly used", in speaking, by native speakers of Japanese, and is "most commonly used", in writing, by native writers of Japanese. In the Japanese spoken form, the vowel "u" is normally devoiced (silent). In the Japanese written form, it's normally in kanji or hiragana, not in roman letters. So the most common use (the Japanese use) is different from the English use. But native speakers and native writers of English are not going to devoice the "u", nor write in kanji, simply because the English use of sushi is less frequent than the Japanese use of the word.
2. Consider the Hawaiian version of Wikipedia. According to the view that you expressed, Hawaiian-language articles should use English spellings whenever the English spelling is "more common than [hawaiianized] versions", right? So Hawaiian-language writers should write "Jesus Christ" instead of "Iesū Kristo", and "soap" instead of "kopa", and "dollar" instead of "kālā", etc., etc., right? Because English use of Jesus Christ, soap, dollar, is "more common" than Hawaiian use of Iesū Kristo, kopa, kālā, right?
3. I'm strongly advocating the position that the "default spelling" should be the native spelling, where native means the language in which the article is written. The native spelling for Hawaiian-language articles is Hawaiian (not English), and the native spelling for English-language articles is English (not Hawaiian). Therefore, this English Wikipedia article on Mauna Loa should use English spellings by default.
4. Returning to aa, ALoan is confusing the spoken form with the written form. Who does not understand that English spelling and English pronunciation most commonly do NOT match? It is inappropriate to expect writers of English, or any other language, to perform orthographic gymnastics to give birth to non-native, pseudo-IPA spellings inspired by an effort to imitate pronunciations. The English word through is pronounced [θɹu], but we do not spell it "θru", and we do not spell rough as "rəf". Likewise, aa is pronounced [ˡa.ʔa]or[ˡʔa.ʔa] in English, but it is spelled "aa" in English.
5. In Hawaiian, the word is pronounced [ʔa.ˡʔaː] and spelled "‘a‘ā". However, in the Hawaiian Dictionary (Pukui and Elbert 1986:389), on the very first page of the English-Hawaiian section, the second entry is "aa. ‘A‘ā. See saying, wāwae." The authors of the Hawaiian Dictionary correctly used the English spelling "aa" of the English word aa, in proper distinction from the Hawaiian spelling『‘a‘ā』of the Hawaiian word ‘a‘ā. (It's the same in the 1971 version of the dictionary. I don't have a copy of the 1957 version, but I bet it's the same there too. The established, correct English spelling has been "aa" for a long time already.)
6. The point about links in Wikipedia for aa versus 'a'a only reflects lack of knowledge among the people who made the links.
7. Are you still against the well established English spelling "aa", even though it has been endorsed through usage by the authors of the Hawaiian Dictionary?Agent X 19:42, 28 July 2006 (UTC)
As I understand it, Mauna Loa, Kilauea, and Loihi are related volcanoes, though with different magma reservoirs, and certainly fed by the same hotspot. But Mauna Loa is roughly 10,000 feet higher than Kilauea and 20,000 feet higher than Loihi, and even further above the ocean floor. Could someone explain for the article how it is that such a massively heavy column of molten stone in an earthquake-prone region can't find some way to deliver itself to a lower destination? 70.15.116.59 (talk) 18:50, 16 December 2007 (UTC)

Mauna Loa is an inactive volcano it can NEVER let me repeat NEVER erupt again some people say its still active but it is NOT because every 2 years it erupted and the last time it erupted was 1984 also people went down into the volcano ( this is called spalunking ) adn found NO magma there which means it can NEVER erupt again NEVER EVER NEVER FOR EVER NEVER EVER NEVER NEVER EVER FOR EVER NEVER erupt again dont listen to anyone else because it is inactive i repeat inactive because i am a spalunker and that is what we found today so it is inactive i repeat inactive uf you say its active you are a LIAR =[[so the correct info is it is inactive =]]]]]]]]]]]]]]]]]]]] thank you for your time =]]]]]]]]]]]]] —Preceding unsigned comment added by 76.119.249.49 (talk) 19:28, 23 February 2008 (UTC)

Hello! This is a note to let the editors of this article know that File:Mauna Loa from the air.jpg will be appearing as picture of the day on October 13, 2011. You can view and edit the POTD blurb at Template:POTD/2011-10-13. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! howcheng {chat} 17:49, 11 October 2011 (UTC)

The small section on climate is totally meaningless as is and should be either expanded or removed. It looks like some global warming scaremonger has inserted that piece of meaningless information so he could point to it as some sort of 'evidence' of global warming. It is in no way informative in its current state. — Preceding unsigned comment added by 122.106.157.135 (talk) 20:23, 3 June 2012 (UTC)
I'm in the process of revitalizing this article. It's an old FA from 2006 that would get demoted in a flash today. There's definitely value in it, but it needs better organization, better language, more information (lots of it), and finally, a trip through the meat grinder, er, FAR. My plan of action for now is to bring it around to FAR when it's good and ready, but until then, comments would be appreciated! ResMar 04:30, 16 December 2012 (UTC)
One thing not explained (so far as I can see) in the article is the estimate on the age at 700k to 1million years when you oldest rock is only 200k years old. Not disputing the age, just looking to see how that was calculated, presumably based on average rate of deposition and total volume of unexposed rock. EdwardLane (talk) 11:57, 28 January 2013 (UTC)
Why doesn't the article give the height above sea level? I propose in the first paragraph "although its peak, at 4170m above sea level, is about 120 feet (37 m) lower than that of its neighbor, Mauna Kea."
Article seems to be locks so I can't edit it. 155.198.206.91 (talk) 10:15, 1 February 2013 (UTC)
I corrected the grossly wrong statement that was in there (before it said Mauna Loa depressed the sea floor by 5 miles, which is deeper than the entire ocean around it) to something that's approximately right by eyeballing ocean depths, but it would be helpful if someone could come up with a citation. I know this is a well known phenomenon but I can't find any myself. KarlM (talk) 00:16, 2 February 2013 (UTC)
"Rising gradually to more than 4 km above sea level, Mauna Loa is the largest volcano on our planet. Its long submarine flanks descend to the sea floor an additional 5 km, and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km." [3]
"All large land masses (such as mountains) also push down upon the Earth's crust due to their enormous weight. So, directly beneath Mauna Loa, the sea floor on which it sits is depressed by and additional 26,000 ft (8000 m)." [4]
"When one considers that the flanks of Mauna Loa sit on sea floor that is about 16,400 ft (5,000 M) deep, the "height" of this volcano relative to neighboring land (the sea floor) is more like 30,080 ft (9,170 m)!...So, directly beneath Mauna Loa, the sea floor on which it sits is depressed by and additional 26,000 ft (8000 m)." [5]

"The massive central portion of the volcano has depressed the sea floor another 8,000 m (26,000 ft) in the shape of an inverted cone, reflecting the profile of the volcano above it. Thus, the total relief of Mauna Loa, from its true base to its summit, is about 17,170 m (56,000 ft)." How High is Mauna Loa? "From the deep ocean floor to the summit of Mauna Kea is more than 8,000 meters - a pile of volcanic basalt more than 5 miles high erupted from the seafloor." FeMO2 Dive Cruise 2007 "Mauna Loa is a giant, active basaltic shield volcano which rises over 4 km above sea level, another 5 km above the north-central Pacific seafloor, and another 8 km above the isostatically depressed seafloor of the Pacific Plate, for a total volcanic height of 17 km." Mauna Loa: A Decade Volcano "Indeed, Mauna Loa is so heavy that it has depressed the seafloor by almost five miles."Sea of Glory: America's Voyage of Discovery, The U.S. Exploring Expedition "The current summit of Mauna Loa stands about 56,000 feet (17,000 m) above the depressed sea floor." Volcanoes Are Monuments to Earth's Origin "Its long submarine flanks descend to the sea floor an additional 5 km, and the sea floor in turn is depressed by Mauna Loa's great mass another 8 km." Volcano Hazards And, finally: "Depression of the oceanic crust is about eight kilometers beneath Mauna Loa, as revealed by seismic experiments." Geological Survey Professional Paper, Volume 1350, Issue 1 |
I think the article currently compares apples to oranges when comparing Mauna Loa to Everest. For the height of Mauna Loa, it uses the height from the root of the mountain somewhere in the lithosphere to the peak, while Everest is mean sea level to the peak. This doesn't seem right. Either the mountains should be compared to their non-rock bases (sea floor vs. base camp?) or both from their root (the asthenosphere level? that could be 250km down). A quick search did not reveal to me a reliable source for the depth of the asthenosphere below Mount Everest. —hike395 (talk) 14:06, 5 February 2013 (UTC)
Read the last reference.Geological Survey Professional Paper, Volume 1350, Issue 1 In particular, go back a few pages from where the link goes to, to Figure 2.6. The others presumably took it from this (they are neither independent nor specialists), and are not wrong in the underlying facts but consistently do a very poor job of translating it into common language. The crust is depressed, but not the seafloor; it's not seafloor when it's got a mountain sitting on top of it! Lava has filled in the depression to the point where little or no depression is noticeable on the seafloor. And as hike395 noted, there was mixing of different measures of height, as well as of km/mi and m/ft. I did some more rewriting to clarify Mauna Loa from seafloor to peak vs. Everest from sea level (which is the usual comparison), and mentioned the underground bulk afterward. See what you think.

This article states that "Mauna Loa is the largest subaerial volcano in both mass and volume, and has historically been thought of as the largest volcano on Earth; however, the recently discovered submerged supervolcano Tamu Massif is many times larger." (bold added by me).This text is based on, and cites, the same source as the Tamu Massif article (which currently states that "Tamu Massif is the largest known volcano on Earth and comparable to the largest known in the solar system, measured by area.").
The source for these statements is an article New Giant Volcano Below Sea Is Largest in the World published on 5 September 2013 on the National Geographic website.
The media interest was triggered a paper by Sager et al. on the Nature Geoscience website, published on 5 September 2013 but corrected on 6 September 2013. The abstract of this Nature Geoscience article states "We suggest that the Tamu Massif could be the largest single volcano on Earth and that it is comparable in size to the largest volcano in the Solar System, Olympus Mons on Mars."
Sager et al. suggesting/claiming that "the Tamu Massif could be the largest single volcano on Earth" (bold added by me) and the media telling us that the Tamu Massif is the largest single volcano on Earth, are two different things.
Tamu Massif is larger than Mauna Loa but is Tamu Massif a single volcano? It could be, but we still cannot say for sure. The scientific jury is still out, because it has not even studied the two-day-old claim yet. The article by Sager et al. is more the start of the process of assessment than its end. Assessment by other scientists of evidence presented in the Sager et al. paper could show that Tamu Massif is not what has been claimed. Tamu Massif may not actually be the largest volcano on Earth, and Mauna Loa could still be the largest volcano on Earth. The media have prematurely reported the suggestions about Tamu Massif as fact. To repeat this in the Mauna Loa article and the Tamu Massif articles on Wikipedia is also premature. Until the findings are confirmed by other geologists, Mauna Loa being replaced by Tamu Massif as the largest volcano on Earth should be described in the Wikipedia articles as a suggestion/claim/possibilty, not a fact. It's too early for Wikipedia to treat Sager et al's claim as fact. I suggest that the Mauna Loa article in Wikipedia should be changed to reflect this uncertainty.

Removed the Tamu Massif bit from the lead and retained "historically considered..". The previous was rather irrelevant for the lead - maybe a note w/in the body once the Tamu info is verified/corroberated. Tamu is Jurassic whereas Mauna Loa remains active.
