Talk:Mount Pinatubo

Role of Katia & Maurice Krafft in evacuations
I think these two ought to be mentioned somewhere in this article. The Wikipedia page on the Krafft's states that their footage helped convince authorities that eruption was imminent and evacuation necessary. Certainly they saved many lives and the same year sacrificed their own in that line of work. Would surely be disrespectful not to mention this somewhere. — Preceding unsigned comment added by 122.61.187.112 (talk) 14:57, 25 May 2018 (UTC)

date in article on Mount Pinatubo
text says "after 500 years of dormancy", however i feel this should be "after 460 years of dormancy"

Novarupta vs. Mt. Pinatubo
The referenced Mount Pinatubo eruption was not the largest of the 20th century. Some references have it as the second largest or the third largest. Please see the discussion at Talk:Novarupta. --Burntnickel 21:32, 9 April 2007 (UTC)

Infobox
In the infobox last eruption date field there is a link to the Smithsonian Global Volcanism site that is appearing as a reference (a number is brackets). This is confusing as this is not the same as the same numbered reference in the main body text and it does not appear in the list of references. I'm not sure what the prefered solution to this problem is. Should the link be removed, made and independant reference or what? --Burntnickel 12:15, 12 April 2007 (UTC)


 * Made into its own reference --- it's pretty easy: I did it. hike395 13:08, 12 April 2007 (UTC)


 * Thanks for fixing that. I wan't sure how to go about it. --Burntnickel 14:02, 12 April 2007 (UTC)

First Magmatic Eruptions: Which is Correct?
In the last paragraph of the "1991 Awakening" section, it clearly states: "The first magmatic eruptions occurred on June 3". However, this is contradicted two sections later in the first paragraph of the "Eruptions Build to a Climax" section, where it states: "On June 7th, the first magmatic eruptions took place". I would correct this information myself, if I knew which one was true. Anyone have any ideas? Curlyiain 15:36, 12 April 2007 (UTC)

Large amounts of new material redacted
The large amount of quoted PD material isn't appropriate to be simply stuck on the end of the article. I moved it to Talk:Mount Pinatubo/new material until we can integrate it back into the article. hike395 05:15, 14 September 2007 (UTC)

Trekking history of Mount Pinatubo
I have added a valuable information on the volcano's trekking history after its eruption in 1994. This information was from the wiki page of Dale Abenojar--Afrescom (talk) 06:54, 9 January 2009 (UTC)

Erupting?
The article says that Mount Pinatubo is an active stratovolcano. What is it doing now? Is it just smoking? --The High Fin Sperm Whale (talk) 00:01, 22 May 2009 (UTC)


 * active doesn't mean currently erupting. I've added a link to help clarify this. Its last eruption was in 1993; the bit of the infobox that said this was broken. -- Avenue (talk) 02:27, 22 May 2009 (UTC)


 * So does active mean that it has erupted recently and could erupt again? --The High Fin Sperm Whale (talk) 19:40, 23 May 2009 (UTC)


 * Here are monthly summaries of its activity since 1991. Since 1995, the concerns have been over lahars more than eruptions, but yes, it could well erupt sometime in the future. -- Avenue (talk) 22:44, 23 May 2009 (UTC)

Innaccurate
"Although the 1991 eruption was one of the largest and most violent of the 20th century, it was weaker than any of the historical eruptions uncovered by geologists. There is some evidence that eruptions at Pinatubo are getting weaker over time, but this is by no means conclusively established." The c. 1450 eruption was even weaker, with VEI of 5! See Global Volcanism Programme. Guanlongwucaii (talk) 08:48, 27 May 2009 (UTC)GuanlongwucaiiHi!!

The appearance of lunar eclipses
According to the article, "in the year following the Pinatubo eruption, the moon was hardly visible at all during eclipses, due to much greater absorption of sunlight by dust in the atmosphere," however in a previous section it is mentioned that sunlight was attenuated by only 10 percent. Such a decrease can readily be identified by instrumentation, but is hard to notice otherwise. If the moon was indeed hardly visible, this is more likely due to aerosol scattering, not absorption. I also think this bit requires a source. Odedee (talk) 21:50, 21 June 2009 (UTC)

Is it active or dormant?
According to the "Activity since 1991" section, "Since 1991, Pinatubo has remained active, with twenty activity events reported in 1992, three in 1993, four in 1994, two in 1995, and one each in 1996 and 2002." But, under "The area since 1991", "Since 1992, the volcano has been dormant." Maybe it's fine, I have no clue -- I only bring it up because those two statements together confused me while reading this article. 31stCenturyMatt (talk) 04:06, 28 July 2009 (UTC)


 * Good call. Text adjusted to reflect scientific status of active. Gubernatoria (talk) 10:57, 28 July 2009 (UTC)

Seperate eruption page
Would it be better to have a page about the volcano and a seperate page about the 1991 eruption event? TimKasoar (talk) 19:19, 22 October 2009 (UTC)


 * I think that sounds reasonable, since the Armero tragedy and the 1980 eruption of Mount St. Helens both have their own articles. --The High Fin Sperm Whale (talk) 21:25, 14 November 2009 (UTC)


 * Oppose. Most of the article is about the 1991 eruption.  Separating it would reduce the remnant to little more than start level. Gubernatoria (talk) 06:07, 16 November 2009 (UTC)
 * Agree. "Separating it would reduce the remnant to little more than start level." this is one of the reasons why the page is undergoing a FA Review. -- Guan long   wucaii  16:02, 9 March 2010 (UTC)

Maybe the article has grown since this discussion? I think the 1991 eruption should be moved to its own page, or at least let's revisit the issue Ninjalectual (talk) 09:45, 30 December 2018 (UTC)

Featured Article?
This article is so good! Why is it no longer a featured article? Has anyone vandalised this page?--Small Boss (talk) 09:34, 20 April 2010 (UTC)


 * It met featured article standards in 2005, but standards have increased. The main reason it failed its FA review was the lack of references. --Avenue (talk) 01:21, 21 April 2010 (UTC)

Effect on global temperature
"This led to a decrease in northern hemisphere average temperatures of 0.5–0.6 °C (0.9–1.1 °F), and a global fall of about 0.4 °C (0.7 °F)."

I think it needs to be made clearer what measure of global temperature is being used here. A fall of this magnitude is not visible in either the CRU or GISS global temperature datasets:

CRU temperatures: http://cdiac.ornl.gov/trends/temp/jonescru/graphics/glnhsh.png - figure from http://cdiac.ornl.gov/trends/temp/jonescru/jones.html

Cabusilan Mountains
These group of mountains which is part of the Zambales Mountain Range is verified by my references as just Cabusilan Mountains not Tri-Cabusilan Mountains. I am following the rules of verifiability per WP:Verifiability and WP:Verifiability, not truth. I could present ten more references to support just Cabusilan. Here, try using Google Books search for Cabusilan. Try searching for 'Tri-Cabusilan' and it will only give you books sourced from Wikipedia! Please stop spreading misinformation by using Wikipedia. Please read why verifiability is important. If Cabusilan is again changed to Tri-Cabusilan, then that would be considered as vandalism and reverted right away. Thanks. - Briarfallen (talk) 10:05, 28 March 2012 (UTC)

infrastructures
In the intro it says "destroying thousands of infrastructures".

Infrastructure is a collective noun so it is already plural and does not need to have an 's' on the end. Philip Sutton (talk) 03:15, 8 February 2013 (UTC)

CO2 emission
What was CO2 emission during explosion and eruption ?

What was total gas emission in atmosphere SO2 NO H2O CO2 etc ?

Aetas
Regarding Aeta people some things seem to be wrong: The majority of the today Filipinos, unlike Mexicans or Argentinians, are not of spanish descent, they are Malayo-Polynesians. This seems to be an underlying misunderstanding in this article. -- Käptn Weltall (talk) 17:42, 26 September 2015 (UTC)
 * The Aeata live all over Luzon, not only around the Pinatubo, while other closely related tribes like the Ati live on other islands.
 * Aetas like other indigenous people in the Philippines have been driven from the lowlands to the mountainsides by the malayo-polynesian immigrants, thousands of years before the arrival of the spaniards.
 * The Aetas around Pinatubo have been living there since thousands of years as well, at least according to the already linked article. Which is interesting, as it means that Aetas have been living there during previous eruptions already.
 * Spanish conquestadores in the Philippines had near to no contact to the indigenous people they christened "Negritos". They fought or dealt with Malayo-Polynesian Datus who were in power of coasts and lowlands.

Mount Pinatubo → Pinatubo – Same with Talk:Mayon. WP:Concise and WP:Commonname: The modifier/title is not needed since there is only one WP:Primary topic for the word "Pinatubo" and it is this article. The volcano is known by its proper name without the word "Mountain" or "Volcano". Based MOS:PHIL Places, the modifier is optional for well-known places. Shhhhwwww!! (talk) 20:36, 13 February 2017 (UTC)
 * Oppose. IMO, the class name, in this case "Mount", is a natural part of the name and is normally included as part of the name of the mountain per WP:NCGN. This is unlike Mayon where sources are torn between calling it Mount Mayon or Mayon Volcano. For Pinatubo, it's always Mount Pinatubo, never Pinatubo Volcano.--RioHondo (talk) 09:01, 15 February 2017 (UTC)
 * Oppose per User:RioHondo. According to the Philippines Geographic Names Database, "Mount" is indeed part of its name.  Volcano guy  00:35, 17 February 2017 (UTC)
 * Oppose As a person following closely media and scientific reports at the time of the eruption in the Philippines and elsewhere, it's always been Mount Pinatubo. Innapoy (talk) 01:01, 19 February 2017 (UTC)

Request split

 * The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

Because there are many suggestions about article Mount Taal and these eruptions to merged. This time I want to request to split that eruption section into separate article namely 1991 eruption of Mount Pinatubo — Preceding unsigned comment added by 110.137.168.126 (talk) 09:27, 17 January 2020 (UTC)
 * Support. This event is a notable one and it deserves its own article. — Emperork (talk) 14:09, 17 January 2020 (UTC)
 * Strongly support This eruption was happened almost 29 years ago but didn't have separate article until now. Because it was one of the deadliest eruption in the Philippine history and the second largest in 20th century, it has more notable to have own article than just a section of mount Pinatubo. — Preceding unsigned comment added by 180.245.111.65 (talk) 21:48, 17 January 2020 (UTC)
 * Support per above. ROBLOXGamingDavid (talk) 05:14, 18 January 2020 (UTC)
 * Support the eruption is notable enough for an article of its own. The section is also way too long for it to be included in the article. ITSQUIETUPTOWN  .public  • talk 05:26, 18 January 2020 (UTC)
 * Support - Agreed on its notability. Granted, not every single volcanic eruption should have its own article. However, this one is worthy of note, and should be easier for readers to locate if searched for. The 1980 eruption of Mount Saint Helens has its own article, as does the 1883 Krakatoa event, and the 1815 Tambora event, and the 1886 Tarawera event, and the 1888 Mount Bandai event, and those were before Wikipedia existed. I have read that one of the reasons that this eruption does not have its own article, is because it was before Wikipedia's time. That doesnt seem to stand up well, logically speaking, due its obvious notability as a major volcanic event of the 20th century. The Pinatubo Eruption of 1991 wasnt in the 1800s, and was easily one of the largest events of the 20th century next to the Novarupta event of 1912, honestly another eruption I'd argue that should have it's own page, possibly, but that is for another discussion. Some volcanic events are notable enough to have their own articles, in my opinion. Maybe I am missing something? SageSolomon (talk) 05:36, 18 January 2020 (UTC)
 * Strong Support. It doesn't make sense not to have an article on the 1991 eruption, which is independently notable on many levels. In fact, I think someone should wp:be bold and just perform the split already.- Alternativity (talk) 01:22, 21 January 2020 (UTC)
