Salina (Italian pronunciation: [saˈliːna]) is one of the Aeolian Islands north of Sicily, Southern Italy.
Salina is divided between three comuni: Santa Marina on the eastern coast, Malfa to the north, and Leni to the south-west.
The most recent eruption on Salina occurred on the western part of the island about 13,000 years ago and formed the semi-circular crater of Pollara; its activity was mainly explosive and produced large pumice deposits.
The gurgling phenomena are at Rinella and are basically caused by the emission of underwater gas (hydrogen sulphate) and vapours.
Salina was the first among the Aeolian islands to protect its environment with a natural preserve, known as the Riserva Naturale del Fossa delle Felci e dei Porri.
The mountainsides of the island are covered with ferns, poplars, chestnut trees and typical Mediterranean vegetation including with caper bushes, prickly pear cactus.
