Vulcano
The island of Vulcano is one of the most interesting in the Aeolian archipelago, because of the exceptional nature of its volcanic phenomena. On the island there used to be 3 craters, one of which, as a result of erosion by sea, presents an interesting cross-section of a volcanic cone, with lava flows and stratifications of pyroplastic material. Off the beach near the faraglioni ( isolated rocks in the sea ), there is the boiling sea-water phenomenon, caused by underwater fumaroles, jets of gas bubbling up thorugh the sea. The medicinal value of these thermal waters, together with the mud baths, in the treatment of various diseases made the island famous.
