Talk:List of large volcanic eruptions

Sortable table
The "sortable table" seems to be unsortable. Does anyone know what might be wrong with it? Rodaen (talk) 11:53, 28 November 2011 (UTC)

Updated Data Required
It seems this page needs a bit of updating. I would think most people would say the Iceland volcano eruption of 2011 and the South American Eruption following that would classify as major eruptions.

Grímsvötn erupted on the 22nd of May 2011. It was only a 4 but still caused a tremendous amount of disruption across the Northern Hemisphere. 2011_Puyehue-Cordón_Caulle_eruption then erupted in June 2011 in Chile causing a massive plume over the Southern Hemisphere. The Earth was definitely having a stretch in these tow months. :) However, I'm not sure what the VEI was for this eruption; it may also have been below 5. — Preceding unsigned comment added by 124.148.132.188 (talk) 23:30, 24 September 2013 (UTC)


 * It is a pity to mix fact with fancy. At the very least one has to consider that unverified material is subjective data. It is difficult enough to find actual fact from contemporary records. But we live in a democracy, so sense and sensibility is redundant. Weatherlawyer (talk) 23:30, 7 February 2015 (UTC)

According to Popocatépetl "A violent VEI-6 eruption in the mid-to late first century CE may have caused the massive migrations that settled Teotihuacan, according to DNA analysis of teeth and bones." so this may be a candidate entry. It's not clear what the scope of "may" is in the passage. Lewis Goudy (talk) 16:04, 27 February 2017 (UTC)

Merge discussion

 * It has been suggested that List of Quaternary volcanic eruptions be merged into this article. (Discuss) Proposed since January 2015.
 * It has been suggested that Timeline of volcanism on Earth be merged into this article. (Discuss) Proposed since January 2015.

Clearly some overlap but the timeline article might be expanded to a 'non list' article with some work, but it's listlike content could be stripped out and merged EdwardLane (talk) 11:17, 26 November 2015 (UTC)

Date conventions
— Sorry, ClueBot reverted your edits as if they were vandalism; of course, they weren't—either style of date (BC vs. BCE) is fine in Wikipedia articles. Don't change the established style, though, per WP:ERA. — Gorthian (talk) 03:37, 28 December 2015 (UTC)

VEI for Puyehue-Cordón Caulle
2A02:C7D:8639:1600:C94D:6639:68A9:799A, 2A02:C7D:8639:1600:F4DE:B544:B5DA:37F, or 2A02:C7D:8639:1600:5939:8B1B:3404:C86F, there are two problems with the edit you keep trying to make: In the future, for lists like this, where there are many factors involved in each entry, please propose your changes on the talk page first to discuss them with other editors.
 * 1) The reference you gave for your removal of Puyehue-Cordón Caulle from the list actually states that the calculated VEI is 4.8, which is a lot closer to 5 than 4 magnitude is 4.8. Also, the same source says that the VEI from the literature is 5, and they reference the source that Wikipedia usually uses for data on recent volcanoes: the Smithsonian Institution Global Volcanism Program.
 * 2) In the same edit, you changed the geological date of five volcanoes with no reason given in your edit summary.

Also, please consider signing up for an account; not only would it be more secure for you, it would also be far less burdensome trying to communicate with you. — Gorthian (talk) 22:06, 6 July 2016 (UTC)


 * 2A02:C7D:8639:1600:5CCF:26EF:309C:9859, Regarding your revert of my edit, I gave you a link right in the edit summary. Will you come here and discuss this? — Gorthian (talk) 02:58, 21 September 2016 (UTC)

The VOGRIPA source webpage for this eruption states "Magnitude: 4.800 (Calculated); Maximum VEI : 5.000 (Literature)". Volcanic eruption magnitude is not VEI (Volcanic Explosivity Index). Magnitude and VEI are different scales calculated by different methods. Volcanic eruptions may have equal or very similar values for their magnitude and VEI but that is, strictly speaking, only coincidence. GeoWriter (talk) 10:26, 30 September 2016 (UTC)


 * I did not know that they weren't the same. I've corrected my statement above. Thanks! — Gorthian (talk) 16:32, 30 September 2016 (UTC)

Sorry only just realised this page is here. The VOGRIPA page states the eruption was 0.7 cu km, which is VEI 4. The reason other sources say VEI 5 is because some calculations put the eruption at approx 1 cu km. Other changes were to correct/add to/update dates for eruptions. This article from respected volcanologist Erik Klemetti also states the eruption is a 4: https://www.wired.com/2011/11/how-big-is-that-scale-and-rates-of-volcanic-eruptions/ 2A02:C7D:8639:1600:5597:61E4:FF53:D5D0 (talk) 14:39, 9 October 2016 (UTC)


 * We always report what reliable sources say for this kind of data. The Wired article is interesting, but not peer reviewed. (It was also written right after the eruption, so does not take into account any modifications of the observed data that may have been made later.) We go by what the VOGRIPA database says, because that's the most reliable source for volcanic data. Making your own calculations is original research, which we do not use in Wikipedia.
 * As a side note; the VOGRIPA site seems to be down at the moment. Did the BGS host recently redesign their site? — Gorthian (talk) 18:49, 9 October 2016 (UTC)

Color changes
What's with all the color tweaking? What are you trying to accomplish? The changes keep coming up on my watchlist, and I don't know what to make of them. — Gorthian (talk) 23:14, 6 January 2017 (UTC)

Remove flags
The flags at the start of some of the volcano names causes the list to sort incorrectly. — Preceding unsigned comment added by 23.119.204.117 (talk) 14:29, 29 April 2017 (UTC)

Flag icons
I've removed the colorful flag icons as useless and redundant links. If the country is important for the table - then add a column for it, leave out the jingoistic icons, and only link the country name one time. Vsmith (talk) 19:59, 13 July 2018 (UTC)

Table sorting and updating (again)
The date column doesn't sort well, because dts wasn't used. When someone updates the data, they should search-and-replace in Template:Dts, if they can. —  OwenBlacker (talk; please &#123;&#123;ping&#125;&#125; me in replies)

Lake Toba
Where does the erupted mass 5,290 come from? I cannot find it in this referenced link, neither in the wiki links in the article's intro. The year 840,000 is correct, but what about the mass?

List of large Holocene volcanic eruptions
This article essentially duplicates List of large volcanic eruptions minus the references. The cutoff criteria also seems to be a VEI of 5 for a volcanic eruption to be "large". - Knowledgekid87 (talk) 19:02, 12 May 2023 (UTC)
