This article lists "vog" as a portmanteau of "volcanic” and “fog," designed to elicit comparisons to “smog.” It may be more appropriate and cleverer to list it as a portmanteau of ‘volcanic” and “smog,” preceded or followed by the point that this is a portmanteau of a portmanteau, but I did not feel strongly enough about this to change the main article. -- Paul
We are on the Kona coast so also breath a lot of this stuff. I think a couple details however are misleading in the article. It is not the "vog" that is emitted, but the Sulfur, I would say. And the later mention of Nitrogen probably should also be Sulfur too, right? There might be NOx also but the main danger seems to be from the Sulfur Dioxide. Also should mention the damage to crops (e.g. Kona Coffee does not seem to mind, but other crops can be damaged). Also I have read about prposals to create arificial vog to combat global warming, and of course there are controversies around them. Need specific references.

User:Gilgamesh added a complaint that it is too US-centric. The question is if the term is in use anywhere except Hawaii? Perhaps there are too many of us transplanted Californians here. Not sure if there are other volcanoes that release as much SO2 on such a long erm basis, and it they call the resulting condition "vog" or not. If it only happens in Hawaii, then what can we really do to make it global? W Nowicki ( talk) 17:48, 25 June 2009 (UTC)
I have a photo taken in early December 2009 from Maui showing a sun at sunset that is shaped like a snowman (small circle above alarger circle.) I would be pleased to see it added to the images in this article. Can anyone tell me how to accomplish that?

In Germany we use the word "Smog" for smog, too, and we don't discern smog and vog. We don't have active vulcanoes here but in the decades before the innergerman wall fell we had lots of problems with sulfur dioxide from coal burning factories. We mostly dealt with not the aerosol but with the acid rain that fell and the dying woods because of that. Today we don't burn that much coal anymore and we have better filters. So, in short, I doubt there's a need to translate this term into German. -- 84.176.225.26 ( talk) 22:36, 4 January 2012 (UTC)
Old conversation, but I will chime in anyway. This particular air effect requires some specific volcanic conditions that are fairly rare: outgassing without heavy fluorine (Iceland), explosive magma (most stratovolcanoes), or ash (typical of most eruptions). The volcanic SO4 and related gases must interact with the atmosphere without ash getting in the way -- and that is extremely rare outside Hawai'i. Atmospheric inversions would magnify the effect, winds direct it, but the non-explosive volcanic event already keeps the SO4 relatively close to the ground. - Tenebris 03:40, 31 October 2013 (UTC) — Preceding unsigned comment added by 198.91.170.20 ( talk)
Apparently a recent major vog hazard in Iceland's capital Reykjavík, blown downwind of the ongoing Fagradalsfjall eruption, and reported here at Just Icelandic. The video also compares it to the Mist Hardships that accompanied the Laki eruption, which, if I'm not mistaken, can be considered a historic cataclysmic vog event. So far I haven't found additional references, like in Google News, and I'd really be interested in corroborating reports. I was thinking it could help us globalize this article beyond just Hawaiʻi. - Gilgamesh ( talk) 00:32, 7 July 2021 (UTC)
