The picture of Mt. Pinatubo is not the climactic eruption. That is a pre-climactic eruption.180.190.47.183 (talk) 11:41, 24 December 2018 (UTC)

Thanks for reporting this. Your observation is correct and therefore I have changed the caption text of this photo.GeoWriter (talk) 15:15, 24 December 2018 (UTC)

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, ...".

I agree with your recommended solution. GeoWriter (talk) 15:59, 1 October 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 called hot-spot volcanoes. The section of subduction volcanos is also quite incomplete and some sections are poorly referenced.
