A geological synthesis

The Aeolian Archipelago from the tectonic point of view, derives from the ditching of the Tyrrhenian Sea in the Pliocene. This event corresponds to the final stage of the Appennines orogenesis along its internal edge. The following stage allowed a deep magma to run up through leaks which gave origin to the Aeolian volcanism.
This volcanic system rests on the bottom of the Tyrrhenian Sea, whose depth varies from 1000 to 3000 meters. It was thought in the Past that the volcanism of the Aeolian Islands had started in the Miocene or in the latter Pliocene: recently some researches, while studying the sea terraces due to the eustatic movements of the Mediterranean, could prove that this volcanism goes back to a more recent age, probably less than a million years ago and, that is, to the Pleistocene. It has been established that at an earlier stage there took shape the islands of Panarea, Filicudi and Alicudi and part of the apparatuses of Salina and Lipari. In a later phase, in the early Pleistocene, the completion of Lipari and Salina and the formation of Vulcano and Stromboli, took place. Radiometric datations on carbonized vegetables made it possible to establish three periods of activity.
In the first period (between 330 and 160 thousand years) the volcanic buildings of Panarea and the dome of Capo Graziano took shape; in the second (between 160 and 130 thousand years) corresponding to the main phase of activity, there took shape: Mount Chirica at Lipari; at Salina Mount Rivi, Capo and Pizzo Corvo; at Alicudi the Montagnola; in the third period (between 130 thousand years up to the present days) there took shape at Lipari, Maunts S. Angelo, Guardia and Pelato; at Salina, Fossa delle Felci, Monte dei Porri, Pollara; at Filicudi, Montagnola and il Torrione; at Alicudi acid lava expansions took place.
The island of Panarea is the oldest apparatus of the Archipelago. Vulcano rises at 100 thousand years with subsequent formations of stratum volcanoes to the South, of Caldera, Fossa and Vulcanello. Stromboli starts its activity (at 40 thousand years) with Vancori; subsequently the Cima took shape and at last the present crater.
The Aeolian volcanism is characterized by an evolution of the nature of magma.
At Aeolian Islands, there is tourist accommodation available in hotels, farm holiday, farmhouse, residence self-catering accommodation, b&b, rooms for rent, holiday homes, camp sites and tourist villages.
