Mount Etna, or simply Etna, is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania. It is located above the convergent plate margin between the African Plate and the Eurasian Plate. It is one of the tallest active volcanoes in Europe, and the tallest peak in Italy south of the Alps with a current height (September 2024) of 3,403 m (11,165 ft), though this varies with summit eruptions. For instance, in 2021 the southeastern crater reached a height of 3,357 m (11,014 ft), but was then surpassed by the Voragine crater after the summer 2024 eruptions. Etna covers an area of 1,190 km2 (459 sq mi) with a basal circumference of 140 km (87 miles). This makes it by far the largest of the four active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. Only Mount Teide on Tenerife in the Canary Islands surpasses it in the whole of the European–North-African region west of the Black Sea. Mount Etna is one of the world's most active volcanoes and is in an almost constant state of activity. The fertile volcanic soils produced from this activity support extensive agriculture, with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south. Due to its history of recent activity and nearby population, Mount Etna has been designated a Decade Volcano by the United Nations. In June 2013, it was added to the list of UNESCO World Heritage Sites.
Etymology and mythology
One view is that the word Etna is from the Greek αἴθω (aíthō), meaning "to burn", through monophthongization of the Ancient Greek pronunciation as seen in Koine Greek phonology, or possibly from a Siculian (or Sicanian?) dialect word (*aith-na, "the fiery one"?) of the same Indo-European origin, namely the root *h₂eydʰ- "to burn; fire". Another view is that the name is derived from the Phoenician word attuna meaning 'furnace' or 'chimney'. In Classical Greek, it is called Αἴτνη (Aítnē), a name given also to Catania and the city originally known as Inessa. In Latin it is called Aetna. In Arabic, it is called Jabal al-Nār (جبل النار, 'the Mountain of Fire'). According to both Roman and Greek mythology, Vulcan/Hephaestus, the god of blacksmithing, had his forge under Mount Etna. In Greek mythology, the deadly monster Typhon was trapped under this mountain by Zeus, the god of the sky and thunder and king of gods, and the forges of Hephaestus were said also to be underneath it. The volcano is also known as Muncibbeḍḍu in Sicilian and Mongibello in Italian, generally regarded as deriving from the Romance word monte/munti plus the Arabic word jabal (جبل), both meaning 'mountain'. According to another hypothesis, the term comes from the Latin Mulciber (qui ignem mulcet, 'he who placates the fire'), one of the Latin names of the god Vulcan. Today, the name Mongibello is used for the area of Mount Etna containing the two central craters, and the craters located southeast and northeast of the volcanic cone. The name Mongibel is found in Arthurian Romance, as the name of the otherworld castle (or realm) of Morgan le Fay and her half-brother, King Arthur, localised at Etna, according to traditions concerning them derived from the stories told by the Breton conteurs who accompanied the Norman occupiers of Sicily. What were originally Welsh conceptions concerning a dwarf king of a paradisal, Celtic underworld became attached to the quasi-historic figure of Arthur as "Ruler of the Antipodes" and were then transplanted into a Sicilian milieu, by Bretons impressed by the already otherworldly associations of the great, volcanic mountain of their new home. Mediaevalist Roger Sherman Loomis quotes passages from the works of Gervase of Tilbury and Caesarius of Heisterbach (dating from the late twelfth century) featuring accounts of Arthur's returning of a lost horse which had strayed into his subterranean kingdom beneath Etna. Caesarius quotes as his authority for the story a certain canon Godescalcus of Bonn, who considered it a matter of historical fact of the time of Emperor Henry's conquest of Sicily c. 1194. Caesarius employs in his account the Latin phrase in monte Gyber ('within Etna') to describe the location of Arthur's kingdom. The Fada de Gibel of the Castle of Gibaldar (Fairy of Etna) appears in Jaufre, the only surviving Arthurian romance in the Occitan language, the composition of which is dated to between 1180 and 1230. However, in Jaufre, while it is clear from her name that the fairy queen in question is Morgan le Fay, the rich underworld queendom of which she is the mistress is accessed not through a fiery grotto on the slopes of Etna, but through a 'fountain' (i.e., a spring) – a circumstance more in keeping with Morgan's original watery, rather than fiery, associations, before her incorporation into the folklore of Sicily. Another Sicilian conception of the fairy realm or castle of Morgan le Fay is the Fata Morgana, an optical phenomenon common in the Strait of Messina.
History of volcanic eruptions
Eruptions of Etna follow multiple patterns. Most occur at the summit, where there are five distinct craters: the Northeast Crater, the Voragine, the Bocca Nuova, and two at the Southeast Crater Complex. Other eruptions occur on the flanks, which have more than 300 vents ranging in size from small holes in the ground to large craters hundreds of metres across. Summit eruptions can be highly explosive and spectacular but rarely threaten the inhabited areas around the volcano. In contrast, flank eruptions can occur down to a few hundred metres altitude, close to or even well within inhabited areas. Numerous villages and small towns lie around or on cones of past flank eruptions. Since the year AD 1600, at least 60 flank eruptions and countless summit eruptions have occurred; nearly half of these have happened since the start of the 20th century. Since 2000, Etna has had four flank eruptions – in 2001, 2002–2003, 2004–2005, and 2008–2009. Summit eruptions occurred in 2006, 2007–2008, January–April 2012, in July–October 2012, December 2018, and again in February 2021.
