  • (Added: vog is volcanic fog, that is, the murky sulphuric haze burped by the volcano on the Big Island which can get particularly bad when the volcano is actively burping a lot AND when the trade winds, which blow out of the east, aren't blowing the vog west into the Pacific.)

  • Kona gets 10 inches of rain a year, but it experiences off-and-on plumes of volcano smoke and fog - called "vog" - that settle along the coast that turn the air into Los Angeles-in-the-tropics.

  • I just learned this word today. Apparently it's a Hawaiian term to describe a dark fog caused by volcanic ash in the air. In that regard, it's similar to smog (smoke + fog).

    March 6, 2007

  • What a very cool three-letter word. I wonder if there should be a list for fog terms. And then I wonder if they all rhyme with "fog."

  • Usage, from "The Explainer" on Slate.com:

    "Even without medical or radioactive waste, volcanoes already release dangerous gases into the environment. In Cameroon, carbon-dioxide pollution from a volcanic crater lake asphyxiated several thousand valley-dwelling people when it displaced the available oxygen. Active volcanoes in Hawaii have caused problems with acid rain and "vog," a combination of volcanic gases and fog."

    I got all excited thinking it was a new word I could add to Wordie. Not only did uselessness beat me to it, but I already knew this word, so... I beat myself to it...?

  • There must be a name for that sensation, or we'll have to come up with one. I do that 10 times a day on Wordie. :-)

  • Do you really, reesetee? Do you think it might be because--oh, I don't know--you have ELEVEN THOUSAND WORDS?!

  • Hmm. *stroking chin* Don't know. I'll have to think about it, c_b. Meantime, why don't you go add some words?? Mwwaaahaha!

  • I knew someone called Vonig who was Vog to his friends.

  • Seems like a variant of fug. Also defined as a "Pejorative word using to curse men without having to slander dogs", on Langmaker.

  • I knew someone named Vishnyu Abeyguneywardena, but we called him Vish.

    Guess that's not quite the same.

  • It's pages like this that make me want to print out wordie and bind it into a book. Wouldn't you just love to flip through the pages and hear the paper rustle? A year from now, will I remember this little thread? If I do, will I be able to find it??? I remember a similar episode on a long-forgotten word. Something about somebody wanted to display their leet knowledge of something. What will we do when we can't remember where to find all the good conversations? :(

    edit: I found it! The comment was made on ennui. My faith in Wordie is restored. :)

    January 10, 2008

  • Hee. It took me a few minutes to realize that eleven thousand words wasn't hyperbole.

  • Vog: Volcanic fog.

    The air in Hawaii is thick with vog.

    June 18, 2009

  • Hawaiians are familiar with the thick haze they call vog, or volcanic smog. When trade winds blow from the northeast, the vog often wraps around the Big Island from Kilauea and settles over the more densely populated western coast. When winds are variable or blow from the south, vog can spread all the way up the Hawaiian isalnd chain to Oahu . . . and beyond.

    Near the active vents, vog is made mostly of sulphur dioxide droplets. Over time and at greater distances, those droplets react with sunlight and chemicals in the air to become more complex sulphur compounds, including sulphuric acid.
