In addition to being a little green paradise, the island of Salina has a particular conformation of volcanic origin. Salina has, in fact, on its territory full six volcanoes are located in the oldest town Pizzo di Corvo, Monte Rivi and in the area of Capo Faro but unfortunately have disappeared over the course of millennia, while the "twins" Trench Ferns and Monte dei Leeks retain their original conical shape. Besides these, several other points on the island of Salina, you can find the so-called "sconcassi" post-volcanic traces: near Rinella, for example.
The island of Salina has had a training complex, held together with two specific periods of volcanic activity, separated by a long period of inactivity. The first period began about 500,000 years ago, when sea level was much lower than at present and Salina was composed of two distinct islands: one to the west, formed by the volcano of the Raven; the other further east, formed by the volcano Cape - Today the North Eastern end of the island - and volcano Monte Rivi to the South West. In the second period, to the south of Monte Rivi was formed volcano Trench Ferns, who share nearly one thousand meters and acts as a giant guardian for Santa Marina Salina and Language. This situation has existed for many hundreds of thousands of years, phase in which the sea and weather have eroded flanks of these volcanoes. The end of the time of volcanic inactivity in Salina, now unified, was marked by the Wurm glaciation, during which consists of the Monte Leeks, covering the old volcano of the Raven. Finally, the last phase of the geological history and the volcanic island of Salina was the opening of the crater of Pollara, at the end of the Wurm glaciation. This crater was formed following a large explosive eruption that destroyed part of the Monte dei Porri.
The Monte Fossa delle Felci and the Monte dei Porri are the highest mountains in the Aeolian archipelago and are the origin of the ancient Greek name of Salina, Didyme, which means their twins.
Monte Fossa delle Felci
The formation of the called "volcano" of the Fossa is due to the products of the first eruptions at the surface layers of black slag - waste of explosive activity in the form of lava fountains, throwing large rocks and lava flows - alternate layers of pumice and ash falls flocked. His activity in the area dates back to somewhere between 125 and 100 thousand years ago. The volcano has also gone through a phase of disruption of its business, shooting between 24,000 and 13,000 years ago.
Monte dei Porri
At the same time the last stages of the eruptive activity of the Fossa ranks second volcano "twin", formed around 100,000 years ago. Before undergoing erosion, inside the volcano has formed a body of water: in the visible today of the crater, on the bottom, have accumulated lacustrine deposits that fill this small basin.
