Etna: smoke ring sent on January 03, 2017 (14:46) by Nicolò Cavallaro. 14 comments, 1662 views.

, hand held. Etna, Italy.

Durante una escursione sul vulcano ho avuto la grande fortuna di assistere ad uno dei fenomeni più insoliti e belli che l'Etna possa regalare e cioè l'emissione di anelli di fumo. In questo caso specifico ne ha prodotto solo uno e sono stato in grado di riprenderlo, ma in passato l'Etna è arrivata a crearne anche centinaia nell'arco di pochi giorni (ad esempio nel 2000). Per chi non lo sapesse è un fenomeno rarissimo, si tratta di anelli vorticosi di vapore e gas che vengono espulsi da uno sfogo vulcanico. La rarità del fenomeno è dovuta al fatto che la loro formazione si verifica solo in condizioni molto particolari e l'Etna è uno dei vulcani al mondo più famosi per questo tipo di manifestazioni. Nonostante le mille teorie in merito, gli scienziati non sono ancora del tutto certi su come effettivamente il vulcano riesca a produrli. La tesi più accreditata attribuisce la genesi di questi anelli ad una precisa configurazione geometrica del foro di uscita e contemporaneamente ad una sequenza di sbuffi intervallati con una certa cadenza e giusta velocità.

Our Etna is always able to surprise us and you know make the most of its beauty, Nicholas. If I may, about to shoot, I would cut a little 'the bottom, which seems to me superfluous.
Best wishes.

Francis, Agata, George, Raphael, thank you very much! :-)

Raffaele I wrote this because I wanted to include the lava flow that, if you notice, "leads" toward the ring. I only say this to explain, not because it does not consider valid your interpretation :-)
Thanks again.
