I think we should be very careful with the second sentence: "Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.[1] " because it is not quite correct: e.g. hot spot volcanos are not linked to tectonic motion. I realize that the sentence is a direct quotation from a NASA document and maybe I'm being picky but the sentence appears in the google knowledge panel when doing a "volcano" google search and it is consulted by thousands of kids all over the world.

Earth's volcanoes do not occur because Earths crust is broken into tectonic plates. They occur because in some spots of the Earth crust, due to convection, melted mantle material (magma) can push through the Earth’s crust causing a volcanic eruption.

I recommend that we should remove the second sentence, and add an hyperlink to "tectonic plates" in the third sentence. Kind regards, Coel Jo (talk) 09:35, 1 October 2020 (UTC)

Coel Jo, thanks for reporting this.

The current text (since 22 April 2014) is "Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle.".

This sentence has a cited source reference written by the Environmental Literacy Council and the National Science Teachers Association (not NASA), which states "Volcanoes occur because the Earth’s crust is broken into 17 major tectonic plates that are rigid but float on a hotter, softer layer in the Earth’s mantle".

The cited source states: "Volcanoes occur..." and it seems that the Wikipedia editor has probably interpreted this to mean that all volcanoes on Earth occur because of plate tectonics, and has introduced this implication into the Wikipedia text. The cited source is correct to say that "Volcanoes" occur because of plate tectonics because some or many volcanoes do indeed occur because of plate tectonics. Unfortunately the source's authors have left themselves vulnerable to being misunderstood and for "Volcanoes" to be interpreted (incorrectly) as "All of Earth's volcanoes". (The authors of the source document should probably have written "Many volcanoes" instead of "Volcanoes" and they should probably have mentioned hot spot volcanoes too).

The current wording of the Wikipedia sentence is not a quotation, it is very close paraphrasing of the cited source, which might constitute a 6 year-long copyright violation because it does not explicitly include an inline acknowledging phrase such as "According to ELC/NSTA, ...".

te tectonics section that recaptures what was correct in that sentence, with a reliable source. --Kent G. Budge (talk) 20:48, 26 November 2020 (UTC)

Volcanes create islands

I’m not enough sure if this is 100% factual or this this information still holds up but, I’m aware volcanoes are responsible for the formation of islands.

I don’t know if I misread the article but, this article doesn’t mention this fact. CycoMa (talk) 04:04, 30 October 2020 (UTC)

You are absolutely right. They are usually hot-spot volcanoes or subduction volcanos. The section of subduction volcanos is also quite incomplete and some sections are poorly referenced.

Mantle plumes

There is a cryptic comment that the mantle plume theory of hotspots has been questioned, with a single source. I think we need a couple more sources, to establish that this is not a fringe view, and some explanation of why the mantle plume hypothesis is considered unsatisfactory and what the alternatives are. While there is certainly vigorous debate on their exact nature and origin, none of the sources in my (admittedly far from comprehensive) library seriously question the mantle plume hypothesis itself, and I want to be sure this section is not giving undue weight to this one source.

This page frankly raises some red flags for me. --Kent G. Budge (talk) 21:37, 26 November 2020 (UTC)

Hazards

I changed 'Sulfur dioxide from the eruption of Huaynaputina probably caused the Russian famine of 1601–1603.[65]' to 'Sulfur dioxide from the eruption of Huaynaputina may have caused the Russian famine of 1601–1603.[65]' The text suggested too high a level of consensus, e.g. the discussion in https://www.volcanocafe.org/the-winter-of-huaynaputina/ The famine was caused by a combination of the Little Ice Age (very cold weather already for some years) and a volcano, but but is not clear that this volcano is Huaynaputina as there was another significant eruption near the same time ABZebra (talk) 16:12, 21 April 2021 (UTC)

most common perception of a volcano is of a conical mountain, spewing lava and poisonous gases from a crater at its summit; however, this describes just one of the many types of volcano. The features of volcanoes are much more complicated and their structure and behavior depends on a number of factors. Some volcanoes have rugged peaks formed by lava domes rather than a summit crater while others have landscape features such as massive plateaus. Vents that issue volcanic material (including lava and ash) and gases (mainly steam and magmatic gases) can develop anywhere on the landform and may give rise to smaller cones such as Puʻu ʻŌʻō on a flank of Hawaii's Kīlauea. Other types of volcano include cryovolcanoes (or ice volcanoes), particularly on some moons of Jupiter, Saturn, and Neptune; and mud volcanoes, which are formations often not associated with known magmatic activity. Active mud volcanoes tend to involve temperatures much lower than those of igneous volcanoes except when the mud volcano is actually a vent of an igneous volcano.

Science

What' is volcano? 49.145.0.52 (talk) 22:40, 2 January 2022 (UTC)

Hello, this article (volcano) can probably explain the concept better than I can, but if you need additional help, your question is probably better asked at the science reference desk than here. This talk page is meant for people to discuss improvements to this article specifically, but you're welcome to ask more general questions about volcanoes at the reference desk. Thanks, Aoi (青い) (talk) 23:16, 2 January 2022 (UTC)

Minor edit: Stratovolcanoes subheading is missing a ). Currently reads as Stratovolcanoes (composite volcanoes. CamphorNoodles (talk) 09:05, 12 April 2022 (UTC)
