Talk:Stratovolcano

Stratovolcano or composite volcano - which, or both?

Title here is "Stratovolcano", but first sentence says "composite" and "strato" only appears at end of first paragraph. I'm not geological, but I think this is confusing. The second para, about volcanologists prefering the "stratovolcano" term helps, but that first sentence bugs me. Can someone in the field please clarify this? Thanks - Peter 00:39, 9 February 2006 (UTC)

Improvements since my note above are wonderful - thanks to all who worked on it. Peter 21:42, 9 February 2006 (UTC)

My science teacher says that composite volcano is the most widely used term in the science field today, and that Stratovolcano is an antiquated term. I think that it probably should be changed to Composite volcano, and say that it is also called a Stratovolcano. Thoughts? 4bit (talk) 03:37, 5 February 2010 (UTC)

I just did a Google Scholar search, and stratovolcano beats composite volcano 7:1 in usage in publications. In publications from 2005 to present (to check what your teacher says about recent usage), the same 7:1 ratio exists. So from a first glance, at least the scientific community prefers "stratovolcano". Awickert (talk) 04:11, 5 February 2010 (UTC)

Volcano to be added as Strato

The Merapi, which is about to erupt on the Island of Java in Indonesia is a clear example of a Strato Volcano--Corney 08:52, 19 April 2006 (UTC)

Images

Anyone else think their usuage is a tad excessive? -b 17:44, 20 August 2006 (UTC)

Four images, why would that be excessive? MadMaxDog 06:52, 21 August 2006 (UTC)

Four images stacked along one side, complimented by only three paragraphs and an extremely long list? I don't think it looks nice at all. -b 02:44, 22 August 2006 (UTC)

I think it's good, for a confusing topic.

The image "Cutaway diagram of subduction zone and an associated stratovolcano" is grossly misleading in terms of scale, with the subducting plate smaller than the volcano. While it is impossible to display such a cross section at real scale, I suggest a better diagram should be provided. — Preceding unsigned comment added by Riverhead2 (talk • contribs) 04:39, 22 June 2011 (UTC)

"Strato Volcano" or "Stratovolcano"?

Is this one word or two? Currently (as of April 10, 2007) the article spells it "stratovolcano" pretty consistently. But some sources spell it "strato volcano." Any experts around here care to say which it is? -- Why Not A Duck 19:33, 10 April 2007 (UTC)

It should be stratovolcano... Every publication I've ever read spells it that way. Snoop0x7b 21:00, 10 April 2007 (UTC)

Yes. It should be "stratovolcano". "Stratovolcano" is the most common usage and has appeared on every volcanological paper I have read. Volcanoguy 17:17, 27 February 2011 (UTC)

Stratovolcano: Most dangerous?

Shouldn't there be a mention of this type of volcano is the potentially most dangerous? IE: the http://en.wikipedia.org/wiki/Pyroclastic_flow that comes from it? There are a few in the USA West, ie: Hood, Rainer, Helens, and of course Vesuvius, and Krakatoa (of which has a "son" since the 1920's. It is this that kills people the quickest and I think should be mentioned. If Krakatoa, it's new descendant ever erupted again like in the 1880's again, it could kill millions.. The pyroclastic flows, and the tsunami's it would create would be devastating beyond the the last eruption when there wasn't too many people living on the islands, and also lack of records. —The preceding unsigned comment was added by Asargeant (talk • contribs).

Well, if you can find a reputable source that documents that stratovolcanoes are the most dangerous, please feel free to put it in! hike395 13:57, 12 May 2007 (UTC)

It's not even true that stratovolcanoes are the most dangerous, so even if a reputable source happened to claim that (like newspapers, which are reputable but often wrong in science-related articles), we should not put it in. Large resurgent-type calderas, which have acquired the popular moniker "supervolcanoes", are by far the potentially most dangerous type of volcanoes. However, there are only a relatively small number of such volcanoes worldwide, and their eruptions are infrequent. Well-known examples include Yellowstone Caldera, Long Valley Caldera, Lake Toba, and Lake Taupo. --Seattle Skier (talk) 18:15, 12 May 2007 (UTC)

I agree that "supervolcanoes" (in the above sense) have the most violent eruptions, and probably present the biggest risk of regional or global catastrophe (although large igneous provinces might be just as bad). But if you look at the eruptive frequencies combined with the number of people at risk, I suspect stratovolcanoes as a group might be more dangerous than all the supervolcanoes. I don't know where to look for a source for that sort of judgement, though. -- Avenue 02:34, 13 May 2007 (UTC)

I agree with you too, that as a group, stratovolcanoes probably present the greatest statistical risk in terms of average fatalities per year worldwide, especially when major side-effects like the Krakatoa tsunamis are included. But I assumed that Asargeant , in referring to "potentially most dangerous" and given the rest of his/her words, was asking about which type of volcano would likely cause the most damage and fatalities if it erupted (i.e. in a single eruption), in which case the resurgent calderas are tops.

In any case, this article is in much need of expansion. A section on hazards, especially focusing on those particularly relevant to stratovolcanoes, would be a useful and necessary addition if we want to work this up to at least Good Article status. --Seattle Skier (talk) 04:58, 13 May 2007 (UTC)

I remember that even shield volcanoes, like Newberry Volcano, can produce pyroclastic flows. Any volcano, be it a stratovolcano, resurgent caldera or anything, which is able to change the weather, is potentially deadly. Guanlong ^wucaii —Preceding undated comment added 09:13, 2 June 2009 (UTC).

Mayon Volcano moved to specific article

The material on Mayon is more appropriate for Mayon Volcano. I moved the material over to Talk:Mayon Volcano/Extra. hike395 (talk) 02:13, 29 April 2008 (UTC)

Problem with magma type

According to the first paragraph stratavolcanoes are characterized by andesitic lava. The article goes on to name the Cascade range and Mt. St. Helens as examples. These mountains have composite lava, layers of andesite and mafic lava. This variation needs to be mentioned to avoid the misleading impression that these volcanoes are strictly andesitic. 96.252.103.113 (talk) 06:25, 9 November 2008 (UTC)

I agree. And not all stratovolcanoes form at subduction zones. Stratovolcanoes like Hekla in Iceland or Mount Edziza in northwestern British Columbia, Canada formed from rift/hotspot volcanism instead. Black Tusk (talk) 06:44, 14 January 2009 (UTC)

And someone added material about composite volcanoes not being the same as stratovolcanoes, which has been subsequently reverted, although two sentences remain with {{fact}} tags. Can an expert confirm or contradict this material? hike395 (talk) 05:42, 20 January 2009 (UTC)

The term composite volcano, is best reserved for those edifices with more than one eruptive peak. Well, according to what I know, composite volcano is the same as stratovolcano while complex volcano and compound volcano are terms for volcanoes with more than one feature.

shield volcano typo

{{editsemiprotected}} sheild volcano should be shield volcano

Volcanic Bombs grammar

Minor quibble - perhaps consider changing very fast speeds to very high speeds. --Peck66 (talk) 01:40, 18 May 2010 (UTC)
