Via NASA’s spaceweather.com Here’s something you don’t see every day, in fact it has only been seen once before by the volcano researchers that got the photo. The diameter of the ring must be huge to be visible at the photo distance. I’m estimating about 1-2km in diameter.
On May 1, 2010, 4:17 Pm Volcano Photographers Steve & Donna O’Meara were stunned when they photographed a perfectly shaped Volcanic Smoke Ring blown out by Eyjafjallajokull Volcano in Southern Iceland.
Here’s the close up view:

“This is a rare phenomenon,” say Steve and Donna. “We’ve only seen it one other time at Italy’s Stromboli volcano in 2001.”
Joseph Licciardi, an earth sciences professor from Oregon State University, was there to see it, too. “The ring was visible for five minutes and then fell apart,” he told the UK Dail Mail. “I am thrilled that I was present at the event.”
In addition to Eyjafjallajokull and Stromboli, volcanic smoke rings have also been observed at Mt Etna. Just how the rings form remains a mystery. It’s possible that bursts of gas through narrow vents would do the job, much like cigar or cigarette smokers blow rings with their mouths.
Smoke rings could soon become more common over Iceland. Eruptions of Eyjafjallajokull are usually followed by even bigger eruptions from the nearby Katla volcano. Indeed, experts are warning that an eruption of Katla may be close at hand. Check the odds!
=========================
Here’s smoke rings on Mt. Etna:
You can make smoke rings yourself with common home hardware:
There’s even underwater bubble rings:
Mauna Loa is 4th on the list of those due to blow (at 10/1). If it does what happens to the CO2 record? What’s the back-up plan?
Actually, I’ve been curious about why the world is taking the CO2 readings from the neighborhood of an active volcano. Doesn’t that skew the readings?
Since smokers sometimes blew smoke rings and smoking is no longer legal in public buildings I’m glad to see that this volcanic smoke ring was blown outdoors and therefore legal.
Did I just write that? Anyway, it’s pretty cool to see.
It burns, burns, burns, burns
The ring of fire, the ring of fire

I know what he’s talking about – just back from a business trip to India!
wasn’t blowing smoke rings the scene in movies right after sex was supposed to have just occurred? Wow, that dates me doesn’t it, no need for symbolics now when the real deal is shown on movie screens.
So its good to know things are going well down there. Well done and all that.
Good to know that the volcano has a sense of humor.
“Explosive eruptions shook two huge volcanos in Central and South America on Friday, forcing thousands of people to flee their homes and disrupting air traffic as ash drifted over major cities.”
Blow baby blow…
Are you having a lend, AW? It looks suspiciously similar in I.D. to that ground based flue.
The smoke and bubble ring structures appear to be electrical-magnetic phenomena due to the tight structures they form. They could be caused from diamagnetic forces acting on water molecules, the same force that causes water droplets.
Ok, this is O/T, but I think I found “the missing heat” laughing at us, just to the southwest of Iceland in this photo.

You can see the ocean currents, unmodeled.
Two cool things on first learning to scuba dive are realizing you’re breathing under water and bubble rings.
If Yellowstone pops, seek strong shelter immediately, crouch down low, place head between knees, and kiss your ass goodbye.
It’s just Lucifer tossing out his old halo; spring cleaning, y’know.
If the smoke ring was the result from a poof, then the volcano is female.
Rhoda R says: “Actually, I’ve been curious about why the world is taking the CO2 readings from the neighborhood of an active volcano. Doesn’t that skew the readings?”
No, the readings are not taken if there’s a local spike in CO2. It’s fairly easy to differentiate between atmospheric CO2 signal and sporadic volcanic releases. See:
http://earthobservatory.nasa.gov/blogs/climateqa/mauna-loa-co2-record/?src=climateqa-rss
“…the CO2 analyzer usually gives a very steady reading which varies by less than 3/10 of a part per million (ppm) from hour to hour….We only detect volcanic CO2 from the Mauna Loa summit late at night at times when the regional winds are light and southerly. Under these conditions, a temperature inversion forms above the ground, and the volcanic emissions are trapped near the surface and travel down our side of the mountain slope. When the volcanic emissions arrive at the observatory, the CO2 analyzer readings increase by several parts per million, and the measured amounts become highly variable for periods of several minutes to a few hours. In the last decade, this has occurred on about 15% of nights between midnight and 6 a.m.”
Actually the real experts (try the eruptions blog) are saying that the recent Katla stories are nothing new and nothing to get excited about. His advice, be concerned when you see the Icelandic Met people announce that they are worried about Katla. The recent Katla stories are just puffery.
Graham Dick says: “Are you having a lend, AW? It looks suspiciously similar in I.D. to that ground based flue.”
That “flue” is a silo.
The Ore-Ida Potato plant in Ontario, Oregon, does this every two minutes or so,
Winter is better, and I suspect a steam component, the volcanic ring, however is quite
a sight…
OK – that is a cool photo – but in the age of photoshop , you have to ask, IS that real?
Dolphins blow bubble rings and play with them:

Appears to be legit IMO.

If you insist. I used to have a Wham-O Air Blaster which needed none of that fancy stuff. Today’s equivalents are at
http://www.waynesthisandthat.com/airblasters.html and
http://www.dansdata.com/airzooka.htm
Once when I was a kid I saw a huge smoke ring from an industrial smoke stack a few miles from home. After using the Air Blaster, I concluded that there was some mildly explosive ignition in what ever fed the smoke stack and that surge made the smoke ring.
That’s just cool – no matter who you are. Ain’t nature grand?
