The heights reached by each island are very different. The Fossa delle Felci Mountain on Salina, for example, has a height that towers above regular hills to 964 metres, followed by Stromboli with 924 metres, which is continuously increasing thanks to frequent explosions from its crater.
The Gran Cratere of La Fossa on Vulcano, with 386 metres of altitude, is the lowest of the Aeolian Islands. The Aeolian Islands are actually much taller than we can see. In fact, the volcanic structure does not rest on the surface of the water, but goes below sea level.
Each island of the archipelago rests on a seabed between 700 and 2000 metres deep. Alicudi, the second smallest of the islands, is actually a volcanic structure whose total height of 2700 metres is higher than that of the highest active volcano in Europe, Mount Etna, which – though 3362 metres high – rests on a 900-metre base.
