The Ionian Sea (Greek Ιόνιο Πέλαγος (Ionio Pelagos), Italian Mare Ionio, Albanian Deti Jon) is an arm of the Mediterranean Sea, south of the Adriatic Sea. It is bounded by southern Italy, including Calabria, Sicily and the Salento peninsula, to the west, by southwestern Albania and a large number of Greek islands, including Corfu, Zante, Kephalonia, Ithaka, and Lefkas to the east. The islands are collectively referred to as the Ionian Islands, and other islands including the Strophades, Sphagia, Schiza, Sapientza and Kythira. The sea is one of the most seismic areas in the world.
