Fault lines and Earth-energy[edit]

Throughout time there are these strange reports of unexplainable things occuring along fault lines during, or immediately after volcanic eruptions:

- Wine become cloudy inside sealed bottles - The sea suddenly becoming severely toxic in the immediate area killing fish/ ect. - Rapists poping out of corners to rape squirrels —Preceding unsigned comment added by 50.80.156.198 (talk) 22:36, 5 April 2011 (UTC)

I was just wondering whether anyone has considered the possibility of earth energy as being the cause of this phenomena?

Basically a huge amount of radiation escaping upwards from faults having these effects. —Preceding unsigned comment added by Mastor3lf (talkcontribs) 07:28, 16 February 2009 (UTC)

I'm not sure on the wine, but there are underwater volcanoes that put out deadly toxins like regular volcanoes, that kills the fish. Firio (talk) 17:37, 24 February 2009 (UTC) volcano said he is smart boy —Preceding unsigned comment added by 117.199.106.235 (talk) 08:30, 10 November 2010 (UTC)

LAVA[edit]

WAT ABOUT LAVA —Preceding unsigned comment added by 65.26.225.136 (talk) 23:46, 13 March 2009 (UTC)

Lava and magma are rocks heated to the liquid state, lava is above ground, magma is below. It dries and turns into igneous rock, it dries fairly fast. What more do you want? Firio (talk) 23:00, 26 March 2009 (UTC)


Magma is molten, contains gases and other volatiles, minerals. Eruption onto the surface causes magma to degas, cool and become solid once its "freezing" temeperature is reached, this is typically 1100 °C for basaltic lavas, and about 650 °Cfor rhyolites and obsidian. It does not "dry" but how fast it freezes depends upon many factors as prove have a look at the Columbia River basalts flows which travelled several kiometres from their source, the Deccan traps basalts which covered an estimated 2000 000 square kilometres.13:50, 9 April 2012 (UTC) — Preceding unsigned comment added by The Geologist (talkcontribs)

Volcanoes in General'[edit]

Volcanic eruptions, are considerably the most catastrophic natural occurrences in the world. A volcanic eruption is extremely potent, and destroys everything on its path. Also, leaving an unforgettable thought on the victims. However, the real question is, what is a Volcano? A Volcano is an inactive mountain, yet a threatening one as well. A volcano is formed by a great accumulation of magma, and a vent in the earths crust through which molten lava ash and gases are ejected through the surface. How are volcanoes formed? Volcanoes initiate as small and unharmful hills, and develop to mountains as they erupt. As I previously mentioned, when volcanoes erupt they release ash deposits and lava flows. The lava then solidifies and forms volcanic glass. The volcanic glass or solidified lava helps the hill to enlarge near the vent or its surroundings by the lava flow streams. Why do Volcanoes erupt? Volcanoes erupt when the core of the earth becomes hot enough to melt its surrounding rocks. Such melted rocks transform into magma. Since magma has a really low density, it elevates to the surface of the earth causing a huge eruption. A more aggressive eruption may occur if magma contains water or dissolved gasses. —Preceding unsigned comment added by 144.90.54.239 (talk) 17:42, 6 April 2009 (UTC)

Cinder Cones[edit]

I believe that not all cinder cones are volcanic cones. Consider pyroclastic cones, tuff cones, and all the others... --Guanlong wucaii —Preceding undated comment added 07:32, 1 June 2009 (UTC).

But how many types of non-volcanic cones are there besides ice cream cones? --The High Fin Sperm Whale (talk) 01:27, 22 October 2009 (UTC)

On the part about the mountain on mars why do we need to know that because none of us are going there? —Preceding unsigned comment added by 67.185.128.229 (talk) 00:47, 12 October 2010 (UTC)

wherever the planet's crust is thin a volcano can form because the crust is so thin and weak that the earth's plates can easily make a volcano. —Preceding unsigned comment added by PacMaster101 (talkcontribs) 01:34, 12 October 2010 (UTC)

Innacurracy[edit]

Basaltic volcanoes don't always erupt effusively. Krakatau (1883) and Fuji (1707) were both explosive. Thus, I am removing it. Guanlong wucaiiGuanlongwucaii —Preceding undated comment added 06:39, 10 June 2009 (UTC). You are not a volcano — Preceding unsigned comment added by 58.64.88.119 (talk) 04:44, 4 January 2013 (UTC)

This once good article fails GCSE Geography[edit]

Hey, I got the first answer to this wrong by using wikipedia:-) Mannafredo (talk) 14:37, 10 June 2009 (UTC)

I will change it. That's embarrassing! Guanlong wucaii 05:49, 13 June 2009 (UTC)Guanlongwucaii
Now I'm really confused [1]. Looks like the Branch Pipe and Sill can become a Dike. The BBC very possibly got things wrong also - almost definitely their spelling of Dike. Mannafredo (talk) 16:30, 17 June 2009 (UTC)
Their spelling of dyke is just fine, being the BBC it would be odd if they didn't use the British spelling. As to 'branch pipes' '"branch pipe" volcano' gets no relevant hits from google scholar, I've never heard of the term myself. The original image file was uploaded by a Polish user, perhaps this term has lost something in translation. It's also possible that the diagram linked above by Mannafredo was generated from the Wikipedia one. Mikenorton (talk) 17:37, 17 June 2009 (UTC)

There is NO SUCH language as British. It is ENGLISH and has been adjusted by people in various other countries. However, the word Dyke is used in the Anglo-Saxon countries, but the Latin European countries use "Dike" and it is the Hispanic influence that has resulted in the USA using DIKE for DYKE. — Preceding unsigned comment added by The Geologist (talkcontribs) 13:56, 9 April 2012 (UTC)

There is however a variety of English usage known as British English, which is what is being referred to above. Mikenorton (talk) 14:34, 9 April 2012 (UTC)
And for what it's worth, "dike" is the primary spelling given in the OED, a distinctly non-American (and non Hispanic!) reference work. OED gives "dyke" only as a variant spelling, with citations for both forms dating back to Middle English. Granted, the entry hasn't been thoroughly revised since 1896, and it's entirely possible that British speakers of English have since decided to make "dyke" their preferred spelling, but they can't reasonably claim that "dike" is an Americanism or an innovation. 206.208.105.129 (talk) 18:12, 12 October 2012 (UTC)

There is NO SUCH LANGUAGE as BRITISH ENGLISH - IT IS ENGLISH. However there is a corruption of English called "Yanklish" which misuses English, uses the wrong spelling which all other countries in the world uses. You can tell if a USA person has written something in "USA English," but it is very difficult to decide which non-USA country wrote /spoke English as spoken and written and used by the rest of the world. Now guess which nationality I am and I'll lay you any odds you like you will be WRONG. — Preceding unsigned comment added by 86.155.170.197 (talk) 13:15, 18 April 2012 (UTC)

Supervolcano in wrong category[edit]

The article lists Supervolcanoes in the section called Volcanic features. But a supervolcano isn't really determined by the shape of the volcano, but the size of the eruption (a supervolcano could probably be a cinder cone, stratovolcano or caldera). --The High Fin Sperm Whale (talk) 18:18, 24 June 2009 (UTC)

Supervolcano has some oddities about it (the page). Isn't a supervolcano any volcano which produces a supervolcanic eruption? If so, then I believe that supervolcanoes should still remain under the category of volcanic features. Guanlong wucaii 10:25, 26 June 2009 (UTC)Guanlongwucaii
Why? Because Volcanic features talks about the shape of different types of volcano (Fissure vents, shield volcanoes, lava domes, etc.) and a supervolcano is any eruption with a VEI of at least eight (1000 cubic kilometres of ejecta). --The High Fin Sperm Whale (talk) 17:07, 22 October 2009 (UTC)

Mt. Kinabalu[edit]

Mt. Kinabalu is granodiorite intrusion, not a volcano. (see Collenette, P. (1964) A Short Account of the Geology and Geological History of Mt Kinabalu, Proceedings of the Royal Society of London. Series B, Biological Sciences, Volume 161, Issue 982, pages 56-63). Mt. Kinabalu is not listed as a volcano at the Smithsonian Global Volcanism Program Borneo webpage [2] nor in Simkin, T. and Siebert, L. (1994) Volcanoes of the World (2nd edition), Tucson, Geoscience Press. Therefore, I have removed the image of Mt. Kinabalu and the associated claim that it is a "renowned volcano", (for the second time). GeoWriter (talk) 11:02, 6 July 2009 (UTC)

New article[edit]

Is there any need for a List of currently erupting volcanoes? Because if nobody objects, I think I'm going to create that article. --The High Fin Sperm Whale (talk) 00:00, 16 October 2009 (UTC)

Well, since no one objected, I'm going to go ahead. Just let me know if I am making a useless article. --The High Fin Sperm Whale (talk) 18:12, 16 October 2009 (UTC)

Excess space with pictures[edit]

Someone should fix this.Jatlas (talk) 02:42, 19 April 2010 (UTC)

Excess pictures, or it would be suitable to add info about the pics, so that the purpose isn't just us meant to say "Aah, Ooh!" (in admiration) but also to learn something new. Rursus dixit. (mbork3!) 15:09, 18 May 2010 (UTC)

Roman vulcanologists' computer models proved incorrect[edit]

According to the article:

  • Vesuvius was thought to be extinct before its famous eruption of AD 79,

According to the Vesuvius page though, there were several written records in the 150 years before the eruption alluding to the fact that it was volcanic. Plus, was this distinction of an "extinct" volcano even around in AD 79? I don't think geology was well understood then.

In addition, this seems to be one of these "really makes you think, huh?" sayings. Ufwuct (talk) 13:44, 19 April 2010 (UTC)

Dense vegetation makes you think so, Pinatubo with forest was regarded as harmless before the eruption too, Pinatubo was not recognised as a volcano by the population. --Chris.urs-o (talk) 13:57, 19 April 2010 (UTC) Vesuvius: "The mountain was then quiet for hundreds of years and was described by Roman writers as having been covered with gardens and vineyards, except at the top which was craggy". It was not present in mind that it is a long time dormant volcano. --Chris.urs-o (talk) 17:07, 28 June 2010 (UTC)

2010 eruptions of Eyjafjallajökull[edit]

I believe 2010 eruptions of Eyjafjallajökull should be added to the top of Decade Volcanos on this article. 85.133.212.80 (talk) 06:15, 23 April 2010 (UTC)

Do not agree, it ages too fast. --Chris.urs-o (talk) 06:19, 23 April 2010 (UTC)
Allegedly it is a minnow-cough in the universe of roaring volcanoes. The media interest is only due to humans constructing stupid air-planes. Rursus dixit. (mbork3!) 15:11, 18 May 2010 (UTC)

Soufriere Hills volcano[edit]

Moved from Talk:Dormant volcano

I wasn't aware that anyone thought Soufriere Hills was extinct; all my sources, even before the event, listed it merely as dormant and quite a dangerous volcano at that.

You could well be right. I'd suggest fixing it, but actually I think this article title should really be redirected to Volcano - it doesn't make too much sense to have separate articles on different states volcanoes can be in. If no-one objects I'll make it a redirect tomorrow. Worldtraveller 20:14, 12 June 2006 (UTC)

I completely agree with consolidating these entries into the general volcano page - the volcano entry mentions "active", "dormant" and "extinct", three popular but relatively inaccurate terms. Soufriere Hills is an excellent example. Many would consider a volcano that had not erupted in over 300 years extinct; geologists know that is a very dangerous assumption indeed. Lamington in New Guinea roared to life in 1951 (after a dormant period of over 6800 years - see http://www.volcano.si.edu/world/volcano.cfm?vnum=0503-01=&volpage=erupt), killing almost 3000 people.

Actually I have a summary to conclude everything within this passage or message about volcanoes. Really all volcanoes aren't formed for earthquakes and such things that are strange. But actually they are made up of the templates underneath the earth, there are "20" different plates throughout our planet. Strangely not all of them have moved in the past "1,000's" of years. About "70%" of the (tectonic) plates have moved, and the other "30%" hasn't. --Jacklyn —Preceding unsigned comment added by 68.43.22.219 (talk) 16:02, 1 November 2010 (UTC)

Traditional beliefs particularly weak[edit]

The section entitled "Traditional beliefs about volcanoes" is particularly weak. Volcanoes feature in mythology and ancient religions in whatever culture they are encountered (notably Greek, Roman, Icelandic, Hawaian). This is hardly reflected by the poor coverage here. Is there no expert out there who can take this on? The Lesser Merlin (talk) 12:22, 16 December 2011 (UTC)

You are correct, but a comprehensive entry on all traditional beliefs about volcanoes would make a full secondary article in and of itself. Perhaps that should be the case and a brief intro and link to it, if there is interest and authors.Wzrd1 (talk) 06:02, 29 January 2012 (UTC)

It is true magic used to be done in volcanoes. It is not real I know but in middle age the folks believed it is true and made things in the volcanoes like magic rings and sowrds, . This beliefs should be put in the article to show this. 169.252.4.21 (talk) 06:08, 13 May 2013 (UTC)Trn

Edinburgh reference in "Extinct" section[edit]

Edinburgh castle is not situated atop an extinct volcano. It is situated near Arthur's seat, which is an extinct volcano at the centre of the city. Can somebody ammend accordingly? — Preceding unsigned comment added by 31.54.168.187 (talk) 23:50, 8 August 2012 (UTC)

Please ignore, I stand corrected. Not about Arthur's Seat but about Edinburgh castle being atop an extinct one. — Preceding unsigned comment added by 31.54.168.187 (talk) 23:53, 8 August 2012 (UTC) ]




ok lets start whith wat volcano means and that has something in common whith thermal energy so if you try to get energy you can only get it by doing the folloing thiings stay away from the volcano [1]

^What in the world are you talking about, bro? 107.0.32.54 (talk) 02:43, 1 December 2012 (UTC)

Etymology[edit]

Perhaps from Lat. volare -to fly + canus -gray (ashes) — Preceding unsigned comment added by 88.207.106.193 (talk) 11:36, 29 April 2013 (UTC)

Volcanoes in fiction[edit]

I would like to request a section on volcanoes in fiction. These feature in Journey to the Centre of the Earth, and a volcano (Mount Doom) is the goal of the quest in The Lord of the Rings. Perhaps such a section could be combined with the section on Traditional Beliefs, e.g. 'Volcanoes in traditional beliefs and fiction'. 111.220.232.137 (talk) 03:55, 11 January 2014 (UTC)

Further to above, many more examples can be found in Pompeii in popular culture. 203.6.146.5 (talk) 00:26, 20 February 2014 (UTC)

2006 or 2007?[edit]

In the section about dormant volcanoes, it says the fourpeaked volcano erupted last in september 2006, but the caption of the relevant image says its september 2007. I dont know which is correct, so someone please fix that. Latias1290 (talk) 10:40, 19 March 2014 (UTC)

Both are correct. It became active in 2006, but it also had eruptive activity in 2007 (pictured). I don't see any need to change it Sailsbystars (talk) 00:42, 2 April 2014 (UTC)
