Incredible images show moment volcano blows rare vortex smoke rings
- 13 days ago
These incredible pictures show Europe's largest active volcano putting on a rare and spectacular 'smoke ring' display.
Holidaymakers caught the moment Mount Etna in Sicily, Italy blew rare volcanic vortex rings into the sky.
The phenomenon happens when rings made of vapour are generated by the release of rapid gas and comes after the opening of a new circular crater.
The circular rings can be seen in the sky above the tourists and volcano at 1pm in the afternoon.
Juliet and Richard, from London, were holidaying in Sicily with their two young sons when they witnessed the rings on April 5.
