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.
