Fault lines and Earth-energy

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 (talk • contribs) 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

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)

Volcanoes in General'

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

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 (talk • contribs) 01:34, 12 October 2010 (UTC)

Innacurracy

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).

This once good article fails GCSE Geography

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)

Supervolcano in wrong category

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

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

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

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

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

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

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

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)
