Titles

[edit]

A better title would be Valles Caldera National Preserve, especially since the world is so filled with "Valle Grandes". --Wetman 19:06, 25 May 2005 (UTC)[reply]

This article is rather confusing. Valles Caldera National Preserve points to this article which is supposedly about Valle Grande but is really about the Preserve. What's more, the first sentence equates the valley (valle) to the entire caldera though Valle Grande is only part of the caldera. Peter (Cactus Pete) 22:55, 26 July 2007 (UTC)[reply]

Valles Caldera National Preserve now redirects to Valles Caldera. --Una Smith (talk) 04:37, 4 June 2008 (UTC)[reply]
Valle Grande is now a proper disambig page, which sets up future separation of these two subjects. No need to hurry though, as they seem to coexist fine at the moment. here 02:17, 4 June 2008 (UTC)[reply]

Parts of the Valles Caldera

[edit]

But don't geoligist say that parts of the Rio Grande Rift and Sangre de Cristo Mountains to the east were modified from the effects of the blast? Or have those effects been eroded away over time?

I read today a statement from a person studying the Valles Caldera NP that it has more lightning strikes than any other "area" other then Orlando. I'm not sure exactly what this means but I believe it. I've never see so much lighting in one area in my entire life. I guess it depends on the definition of area.

Is the Valles Caldera dormant or extinct at the moment? Does anyone know if there are any tiltmetres there, or seismic recording devices? Darkmind1970 11:22, 5 December 2006 (UTC)[reply]

Dormant. There are fumaroles over there, so there is a slight chance that it may erupt. Global Volcanism Programme Guanlongwucaii (talk) 11:13, 25 May 2009 (UTC)Guanlongwucaii[reply]
"Extinct" certainly isn't correct, as User:Guanlongwucaii points out. Use of the term "dormant" is notoriously inexact and probably should be discouraged. There is an excellent new book on the caldera by geologist Fraser Goff that talks about the eruptive status (among many other things) at some length; I'll try to adapt some verbiage from it to the article when I get home from work. Rhyolite volcanism typically has a "slow tempo" (another nice phrase from a good reference, Wood and Kienle, Volcanoes of North America) and the caldera and Jemez Mountains should certainly be considered potentially active, even though nothing more exciting than fumaroles is currently happening. Let me see if I can find some primary sources regarding instrumentation; the range is monitored for seismicity, although there are no tiltmeters that I know of. -- Bill-on-the-Hill (talk) 19:22, 16 June 2009 (UTC)[reply]

Merge "Valle Grande, New Mexico" here?

[edit]

It seems like "Valles Caldera" (this article) is already mostly functioning as the article for Valle Grande. There exists a separate article for it however. Seems like an obvious merge but I thought I'd wait for comments since I'm not familiar with the area. Jason Quinn (talk) 16:28, 5 April 2012 (UTC)[reply]

I support a merge. I'd never heard that part of the caldera was a dried lake bed until I read the NASA page (interesting!). Most references I've seen refer to the caldera as a whole. - J-Mo Talk to Me Email Me 03:01, 12 April 2012 (UTC)[reply]
Fully support a merger based on how little new information is on the Valle Grande article compared with the Caldera article. Coinmanj (talk) 02:35, 2 November 2012 (UTC)[reply]

Supervolcano

[edit]

This is not a supervolcano. The term "supervolcano" implies a volcanic center that has had an eruption of magnitude 8 on the Volcano Explosivity Index (VEI), meaning the measured deposits for that eruption is greater than 1,000 cubic kilometers (240 cubic miles). https://volcanoes.usgs.gov/volcanoes/yellowstone/yellowstone_sub_page_49.html

The VC erupted only 300 cubic kilometers - which means the VC does not qualify.— Preceding unsigned comment added by Iwearvelcroshoes (talkcontribs)

@Iwearvelcroshoes: Alas, the base-10 logarithm of 1000/300 is about 0.522 and in practice, large VEI-7 volcanoes are also considered supervolcanoes, such as the Long Valley Caldera.--Jasper Deng (talk) 19:28, 7 February 2018 (UTC)[reply]
@Jasper Deng:Thank you for the response. Please provide academic (peer-reviewed) support for the VEI-7 statement and I will happily forfeit my edits. I have searched extensively and have been unable to find a peer-reviewed journal that supports your statement.
@Iwearvelcroshoes: A straightforward search of JSTOR reveals things like [1]. Valles may be debateable (no sources specifically on Valles) but Long Valley Caldera is universally considered a supervolcano, even though its largest eruption only had twice as much ejecta as Valles. Campi Flegrei, with a slightly smaller maximum eruption (the Campanian Ignimbrite eruption), is considered to be a supervolcano ([2]).--Jasper Deng (talk) 19:47, 7 February 2018 (UTC)[reply]
@Iwearvelcroshoes: And in any case, if you really want to restore the stricter VEI 8 criterion, you need to talk this out at Talk:Supervolcano, where editors have long tossed out the VEI 8 designation.--Jasper Deng (talk) 19:53, 7 February 2018 (UTC)[reply]
@Jasper Deng: Long Valley is indeed a supervolcano, I would be extremely interested in any more recent peer-reviewed sources citing the Valles Caldera as one though. Please do share. The [3] piece is from 2006.Iwearvelcroshoes (talk) 19:59, 7 February 2018 (UTC)[reply]
- Hello! @Iwearvelcroshoes, @Jasper Deng
-- I am working on adding to this article as a university student. I've just come across a recent article looking at the Otowi member of the Bandelier tuff at Valles Caldera. Based on the volume of this one eruptive event, they're placing it at a VEI of ~ 8, on the low end of the scale, but in the super eruption category. It's a research article in the Bulletin of Volcanology.

Climate

[edit]

When viewed in Google Earth, this file Global_1986-2010_KG_5m.kmz (available here http://koeppen-geiger.vu-wien.ac.at/present.htm ) indicates the Köppen climate classification for the Valles Caldera is Dfb. The current article states it has a Dfc climate, but I am unable to find a rigorous source for that classification. Can someone here provide it? — Preceding unsigned comment added by Leveretth (talkcontribs) 17:16, 28 June 2021 UTC (UTC)

Resurgent vs Lava Domes

[edit]

The article Resurgent dome states that resurgent domes are not Lava domes. This article uses the term resurgent lava dome and some text does imply some kind of hybrid of the two. What is the truth here? Tfdavisatsnetnet (talk) 03:33, 26 May 2024 (UTC)[reply]

Student interest and additional info

[edit]

Hello there,

My name is Ashley and I'm taking a volcanology course at UNM where we are tasked with creating or adding to a Wikipedia article. The Valles Caldera is one of the most beautiful places I have been with stunning geologic features and it's in my "backyard". Geologically, I find the Jemez lineament to be of great interest and it is geology important to this feature and relates to accretionary events like those of the Yavapai and Mazatzal orogonies. My main focus will be adding to and bolstering the sources for the geologic section, along with some small edits/adjustments for readability. I will adjust the Lead as needed to make sure it continues to reflect the evolving content of the article.

I look forward to working with all of you.
