In a breathtaking display, the iconic Mount Etna in Sicily, southern Italy, belched impressive smoke rings. At times, due to the light, the circles even took on a pink hue.
Volcanic vortex rings are natural, near-perfect circles of gas emitted by a volcano under specific conditions.
Scientists say Mount Etna emits more of these rings than any other volcano on Earth, making the event particularly notable.
Why does it happen?
It is a relatively rare phenomenon caused by a constant release of vapors and gases. The gaseous mass rises quickly through the central part of the crater, promoting the formation of rings by wrapping the gas around itself in a vortex movement.
The rings led local residents to nickname the volcano “Lady of the Rings”.
