Seven volcanic islands off northern Sicily gave their name to two of the classic types of volcanic eruption. Stromboli has erupted at short, regular intervals for at least two thousand years, while Vulcano’s fumaroles and Lipari’s obsidian cliffs show the same subduction system at different stages of its life.
At a glance
The Aeolian Islands lie in the Tyrrhenian Sea north of Sicily and comprise seven volcanic islands: Lipari, Vulcano, Stromboli, Salina, Panarea, Alicudi and Filicudi. They sit above an active subduction zone, where the Ionian plate slides beneath the Tyrrhenian plate at roughly 2.5 centimetres a year, producing a range of volcanic behaviour from Vulcano’s short explosive bursts to Stromboli’s steady low-intensity activity and the gentler lava flows seen on the older islands. These three styles, Vulcanian, Strombolian and Aeolian, were first identified and named in this archipelago.
Lipari is the largest and most populated island, with its main town built around a castle and an archaeological museum. Salina is the only island in the group without recent volcanic activity and is known for its malvasia wine. Panarea, the smallest inhabited island, has submarine volcanic vents off its eastern coast. Alicudi and Filicudi remain the least developed of the seven.
Key facts
- Archipelago: seven islands, roughly 12,500 hectares in total
- Stromboli: 924 metres, the highest point in the archipelago, in near-continuous eruption for at least 2,000 years
- Sciara del Fuoco: a collapse depression on Stromboli’s northwest flank, about 2.5 km long, 800 m wide and 400 m deep, formed roughly 5,000 years ago, which channels lava directly into the sea
- Vulcano: the southernmost active island, with the Gran Cratere at 391 m and active sulfur fumaroles; its most recent eruption ran from 1888 to 1890
- Population: around 14,000 across the archipelago
- Status: inscribed as a UNESCO World Heritage Site in 2000 (reference 908)
History
The islands take their name from Aeolus, ruler of the winds in Greek mythology, who according to Homer’s Odyssey kept the unfavourable winds sealed in a bag in a cave on one of these islands. The name recorded in the Homeric poems, around the eighth century BCE, has stuck to the archipelago ever since.
Greek settlers from Knidos and Rhodes founded a colony at Lipari around 580 BCE, drawn by the islands’ obsidian, the volcanic glass that became one of the most widely traded materials in the prehistoric Mediterranean, reaching sites thousands of kilometres away between roughly 4500 and 2000 BCE. Centuries later, in 260 BCE, the harbour at Lipari was the scene of the Battle of the Lipari Islands, the first major naval engagement of the First Punic War, in which a Roman fleet under Gnaeus Cornelius Scipio was ambushed and captured by the Carthaginians.
Under Mussolini’s regime, between 1926 and 1943, Lipari served as a place of compulsory exile for political prisoners, including the anti-fascist editor Carlo Rosselli, who escaped from the island in 1929. The Aeolian Islands were inscribed on the UNESCO World Heritage List in 2000, reference number 908.
What you see
On Stromboli, the Sciara del Fuoco is the dominant feature: a steep scar running down to the sea, down which incandescent bombs and lava from the summit’s three active craters travel every ten to twenty minutes. Larger, less frequent paroxysmal eruptions occur every few years and can send pyroclastic flows down the same slope. Access to the summit is only permitted with authorised guides, following restrictions introduced by INGV.
Vulcano’s Gran Cratere can be reached on foot from the port, past fumaroles encrusted in yellow sulfur that vent hot gas, and a thermal mud pool near the harbour where bathers pick up the same yellow mineral deposits. Lipari’s town is built around its castle, which houses the Museo Eoliano, home to a large prehistoric collection of obsidian tools, ceramics and Bronze Age bronze swords; the old obsidian quarry at Canneto, just outside town, is visible from the sea.
Salina’s slopes are given over to vineyards producing the malvasia delle Lipari wine, and the island was used as a filming location for Il Postino. Panarea’s coastline conceals submarine volcanic vents discovered in the early 2000s.
Practical information
- Stromboli summit access: permitted only with certified guides in small groups, following INGV authorisation rules introduced in 2020; check current conditions with an authorised operator before travelling
- Accommodation: rooms on Stromboli and Lipari are limited, especially in summer, and early booking is advisable
- Island hopping: hydrofoils and ferries link Lipari, Vulcano, Salina, Panarea, Stromboli, Alicudi and Filicudi, with car transport possible to Lipari, Vulcano and Salina
- Booking tours: guided Stromboli hikes are arranged through INGV-authorised operators; confirm current requirements directly with them
Getting there
Milazzo, in Messina province, is the main gateway port for the Aeolian Islands, reached by bus from Messina and Palermo or by train to Messina from Rome and Milan followed by a bus connection. Hydrofoils and slower ferries run from Milazzo to Lipari and on to the other islands, including Stromboli; travellers arriving by air typically fly into Reggio Calabria or Catania and continue to Messina by train or bus before picking up the ferry.
Nearby
- Vulcano — a short hydrofoil hop from Lipari, known for its crater walk and sulfur fumaroles
- Salina — reachable from Lipari, the archipelago’s only non-volcanic island and centre of malvasia wine production
- Panarea — the smallest inhabited island, with submarine volcanic vents off its eastern shore
- Filicudi and Alicudi — the westernmost and least developed islands of the group
