File:Roque Cinchado with Teide in 2014 (1).JPG[edit]

I still think it is volcanic degassing, because the rocks at the summit are geothermally altered (colour difference to the other parts of the mountain) exactly under the starting point of the clouds (high temperature area) - and Teide is an active volcano, so degassing would not be out of the question. See eg. also Leirhnjúkur area in Iceland ( File:Leirhnjúkur 19.05.2008 13-07-56.jpg ).Reykholt (talk) 16:25, 3 June 2014 (UTC)

Hi Reykholt, thanks for your comment. I am sure that it is not. We climbed the pictured top of the volcano later (exactly fallowing the path where suggested degassing occurred) and they were no signs for volcanic activity (in last years). Also, no smells for volcanic gasses and the final, we actually saw how the normal clouds were approaching to the summit of the volcano and than spreading around summit.
PS: I am professional volcanologist (alright, focusing about volcanoes on Mars, but still...) and I will be really, really, really, really exited if this was lava degassing. Unfortunately, I was not lucky enough to see active volcano on Tenerife (or elsewhere) :( Even on Iceland with Eyjafjallajökull I was there half year earlier :(( Best regards --Chmee2 (talk) 19:35, 3 June 2014 (UTC)
I see. When you say, you saw Teide otherwise yourself, that is fine with me.
Otherwise, it's a question of definitions. In my understanding, a volcano is not only active, when it is erupting, but also when there are eg. gasses or hot springs like in Landmannalaugar where you also were (Torfajökull's last eruptions were in the 15th century, Krafla's in the 1980s) or even all volcanoes which have had eruptions in the Holocene. (See also GVP: "How many active volcanoes are there in the world? --- The answer to this common question depends upon use of the word "active." At least 20 volcanoes will probably be erupting as you read these words (Italy's Stromboli, for example, has been erupting for more than a thousand years); roughly 60 erupted each year through the 1990s; 154 in the full decade 1990-1999; about 550 have had historically documented eruptions; about 1300 (and perhaps more than 1500) have erupted in the Holocene (past 10,000 years); and some estimates of young seafloor volcanoes exceed a million. Because dormant intervals between major eruptions at a single volcano may last hundreds to thousands of years, dwarfing the relatively short historical record in many regions, it is misleading to restrict usage of "active volcano" to recorded human memories: we prefer to add another identifying word (e.g. "historically active" or "Holocene volcano", - http://volcano.si.edu/faq.cfm#q3 ). Krýsuvík volcanic system has eg. had its last eruptions in the 13th century, but is regarded as "active" by Thor Thordarson in "Classic Geology in Europe 3. Iceland" (p.14).
Following these definitions, you have been hiking on active volcanoes. Teide had its last eruptions in 1909 and Torfajökull (Landmannalaugar) is also on the list of Thor Thordarson. And on its list is also included Tindfjöll/Tindfjallajökull in south Iceland, you saw it most certainly, it is north of Eyjafjallajökull. This is a volcanic system, which erupted last even not in the Holocene, but around 50.000 years ago, but it has active geothermal areas at its feet.
BTW: I saw two volcanic eruptions in Iceland and wrote a not so small part of the article on Eyjafjallajökull and the other on its 2010 eruptions in the German Wikipedia.Reykholt (talk) 21:35, 3 June 2014 (UTC)
Of course, you are right in this. I might chose better term "active volcanic phase of eruption" instead of "active volcano". But my point was, that I was never lucky enough to see how the lava is leaving the subsurface or how is it fragmented as a result of magma degassing or water/magma interaction. Still hope that I will have some luck in some of my next trips :) Best regards --Chmee2 (talk) 10:46, 7 June 2014 (UTC)
