This is one of those natural phenomena you have to see you believe. Apparently, when conditions are just right, you just might witness the rare volcanic smoke ring. Scroll down to see. That last picture truly blows me away.
This massive smoke ring came from a Volcano in Italy.
The scientific name for this phenomenon is a “vortex ring”—an explosion of steam from a small circular opening in a volcano’s crater.
The air in the center moves faster than the air at the edge, which causes the aerial donut to spin and allows it to maintain its shape.
Such rings can travel as far as half a mile above the Earth’s surface.
Rings can last up to 10 minutes when well-formed.
They can measure up to 160 feet across.
