The current article makes the bizarre claim that "Rift zones are a prevalent feature on shield volcanoes that is rare on other volcanic types. The large, decentralized shape of Hawaiian volcanoes as compared to their smaller, symmetrical Icelandic cousins can be attributed to rift eruptions". What part of this makes any sense at all? Has the author ever even compared a map of Hawaii with a map of Iceland? It's Iceland that's "large", "decentralized" and "asymmetrical" full of fissure/rift eruptions. Wikipedia itself spends 3 times as long talking about Iceland's fissures as it does Hawaii's. Iceland is far more fissure eruption prone than Hawaii, lying on a divergent plate boundary. We've got a fissure eruption ongoing right now on Bárðarbunga/Holuhraun that's already erupted more than any Hawaiian eruption in modern history, at a faster rate than any of them too. And it's hardly a record setter - one of our fissure eruptions in the 1700s was over 20 kilometers long, released 120 million tonnes of SO2, and is responsible for as many as 6 million deaths worldwide. And they're also implying that Iceland doesn't have shield volcanoes, when our biggest volcanoes are all shields. (including Bárðarbunga). Basically, what on Earth is this article talking about here? -- 213.176.153.100 ( talk) 12:55, 9 October 2014 (UTC)
If anything, Hawaii's volcanoes are remarkable for precisely the opposite - how centralized, symmetric, and consistent they are in where they erupt, which is what's allowed Mauna Loa to develop to such a tremendous height, versus Iceland which is much larger and and has a significantly higher average annual flow rate, but whose largest mountain is only 2100 meters tall (well, okay, glaciers helped with that too...). -- 213.176.153.100 ( talk) 13:03, 9 October 2014 (UTC)
Shield volcanoes are formed by lava flows of low viscosity — lava that flows easily.
This should be changed to:
Shield volcanoes are formed by lava flows of high viscosity — lava that flows easily. —The preceding unsigned comment was added by 24.83.141.120 ( talk • contribs).
actually lava with a low viscosity moves slowly while lava with a high viscosity moves quickly —Preceding unsigned comment added by 24.13.71.167 ( talk) 00:02, 5 February 2008 (UTC)
Changed the section title "FAQ" which is very unencyclopedic to "Information" which isn't much better. More thought needed... 217.34.222.220 ( talk) 13:17, 14 July 2008 (UTC)

Why does the Encyclopedia of Volcanoes refer to both shield volcanoes and stratovolcanoes as 'composite volcanoes'? -- Guan long wucaii 14:30, 11 February 2010 (UTC)
This article needs a major rewrite big time. I just reworded the first sentence in the introduction from "A Shield volcano is a type of volcano built almost entirely of fluid lava flows." to "A Shield volcano is a type of volcano commonly built almost entirely of fluid lava flows." to make it more obvious. Pyroclastic shields are NOT made almost entirely of fluid lava flows. Instead, they are composed largely of pyroclastic material. Another less common type of shield volcano are those composed of andesite and/or rhyolite. But it seems like this article focuses primarly on the most common shields composed of basalt as far as I'm aware of. I would add a bit for the andesite and rhyolite shields, but I do not know the geology of them too well. Volcano guy 03:30, 22 August 2010 (UTC)
I was asked to give a recommendation on how to organize this article. I think that the key point about Shield volcanoes is that they form from low-viscosity mafic lavas. That can be used as a starting point from which to investigate the different environments that produce shield volcanoes and as an underlying theme. So perhaps:
That's mostly off the top of my head, so don't put too much stock in it, but I sort of like it as a scheme. Cheers, Awickert ( talk) 05:46, 13 February 2011 (UTC)
The section has only two sentences regarding volcanoes which can be easily absorbed in the rest of the article. The rest belongs on shield because it discusses the etymology of that word and has nothing to do with volcanoes. 173.112.160.152 ( talk) 04:12, 22 June 2011 (UTC)
For example, the popup information for a volcano link in the middle of the Pacific says its in California. Another popup says its in Congo but the link is in South Africa. A third names a volcano on New Zealand but it is down near the Antarctic. Someone should align the image and the links. — Preceding unsigned comment added by 101.103.131.42 ( talk) 09:39, 3 January 2012 (UTC)
Ok looking at this page I see a few issues.
The first stumbling block is the definition of 'shield volcano'
Shield volcanoes are one of the three major types of volcanoes, distinguished from the two other major volcanic types, stratovolcanoes and cinder cones, by distinct differences in structure and composition. Stratovolcanoes are built up by the accumulation of thick, viscous lavas, whereas cinder cones are constructed of tephra ejected in explosive eruptions. In comparison, shield volcanoes are built of relatively weakly viscous basaltic lavas that erupts in longer cycles than that of a stratovolcano.[3] Shield volcanoes are distinctive products of hotspot volcanism, but can form at rift and subduction zones as well.
Ok so assuming that is correct I see there is a section further down about pyroclastic shields - incidentally that page has no citations for it's definition. It says it is an uncommon type of shield volcano - it seems (based on the quoted definitions) that they are more like an uncommon type of cinder cone - in that it looks like a shield volcano rather than being steep sided.
If we take that idea as true then moving the subsection on pyroclastic shields into the cinder cone article would make sense, and then there is no contradiction to the given definition, low viscosity lavas etc etc . Also that then allows the three "major" types of volcano (shield/strato/cinder) to be cleanly defined as non conflicting entities.
I don't have a source to back up that proposal - I'm just looking at the conflict that is already within this particular page and thinking about how it might be tidied up. Anyway if felt just slightly more confident that I was right I'd have been bold and moved the pyroclastic shield section into the cinder cone article. What do you think? EdwardLane ( talk) 10:44, 13 September 2012 (UTC)
The folks at GVP are seemingly redefining "shield volcano", are there any other sources which support the inclusion of pyroclastic shield shaped features as "shield volcanoes"? The standard definition is a volcano built by highly fluid mafic lavas and pyroclatic piles are not fluid or mafic. Yes, "shield shaped" piles of pyroclastics do exist and perhaps "pyroclastic shield" is a valid term, but they don't fit the basic definition of a shield volcano. Methinks we need supporting sources here for such a basic redefinition - as in peer reviewed publications. Vsmith ( talk) 13:59, 27 November 2012 (UTC)
The single ext link in the unref'd pyroclastic shield article is a one liner stating: A pyroclastic shield volcano is a shield volcano covered with pyroclastic deposits from later eruptions. [1] and that is not a WP:RS. Vsmith ( talk) 14:04, 27 November 2012 (UTC)
The one for La Grille mentions that it is in "the Cameron". This should be "Comoros". — Preceding unsigned comment added by 198.49.222.20 ( talk) 15:54, 13 September 2012 (UTC)
Post shield stage is an orphan stub, is it worth an article on its own, or just merge it into a subsection of this article? EdwardLane ( talk) 22:17, 17 June 2013 (UTC)
