Salina is an island in the Aeolian Islands (Italian: Isole Eolie, Sicilian: Ìsuli Eoli) north of Sicily, southern Italy. It is the second largest island in the archipelago.

Salina is divided between three comuni: Santa Marina on the eastern coast, Malfa to the north, and Leni to the south-west. From Leni down towards the sea are the villages of Valdichiesa and Rinella. The other smaller villages are Capo Faro, Pollara and Lingua.

There are currently approximately 4,000 residents living on the island.

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge, for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from the core-mantle boundary, 3,000 km deep in the Earth.
