Height
Etna towers around 3,350 metres (around 11,050 feet) above sea level and is 35 kilometres (22 miles) in diameter, although the volcanic activity has changed the mountain's height over time

Recent eruptions
Since 2001, the mountain has had 16 eruptions. The most recent pyroclastic flows with significant reach were recorded on February 10 in 2022, October 23 in 2021, December 13 in 2020, and February 11 in 2014, said Marco Viccaro, president of Italy's national volcanology association

Uniqueness 
While the airport at Catania, eastern Sicily's largest city, usually has to close down for hours or days because of the ash in the air making it dangerous to fly, the eruptions also have benefits leading to fertile farmland and tourim in the area

History of eruptions
Some of the most popular historic eruptions include one in 396 BC that has been credited with keeping the army of Carthage at bay.

In 1669, in what has been considered the volcano's worst-known eruption, lava buried a swath of Catania, about 23 kilometres (15 miles) away and devastated dozens of villages. 

An eruption in 1928 cut off a rail route circling the mountain's base

Literature
In literature, some of the most popular references to Mount Etna have been made in Homer's 'Odyssey', Virgil's 'Aeneid' and Pietro Bembo's poem 'De Aetna' among others
