It is not the first time that Etna has managed to produce the circular steam rings and photographs have been taken of them since the 1970s and notably in the year 2000. Here, it is possible to see the steam rings above the volcano

German volcanologist Dr Tom Pfeiffer believes the reason for the unusual smokey formations is because the violent eruption had changed the morphology of a vent

Mount Etna is an active volcano on the east coast of Sicily, Italy, close to the cities of Messina and Catania. It lies on a convergent plate margin between the African plate and the Erasian Plate. It is the tallest active volcano on the European continent at 3,329m high

When Etna started to erupt last month (pictured) none of the villages of Catania, dotted around the mountain, needed to be evacuated, though airspace over the southern Italian island was briefly closed

More than 25 per cent of Sicily's population lives on Etna's slopes, and it is the main source of income for the island - a combination of agriculture, due to its rich volcanic soil, and tourism. Here, Etna is pictured erupting last month
