Graham Island or Isola Ferdinandea was an island in the Mediterranean Sea near Sicily. It has, on more than one occasion, risen above the surface of the Mediterranean via volcanic action and soon thereafter been washed away. Since 300 BC this cycle of events has occurred four times. The island was part of the submarine volcano Empedocles, 30 km (19 mi) south of Sicily, which is one of a number of underwater volcanoes known as the Campi Flegrei del Mar di Sicilia.
