Campos Flégreos
Volcanic activity at Ferdinandea island was first recorded during the First Punic War during the 3rd century BC. The island is believed to have appeared and disappeared four or five times since then. Several eruptions have been reported since the 17th century AD. The island is located in a volcanic area known as the "Campi Flegrei del Mar di Sicilia" (Phlegraean Fields of the Sea of Sicily), in between Sicily and Tunisia in the Mediterranean Sea. Many submarine volcanoes (seamounts) exist in the region, as well as some volcanic islands such as Pantelleria.
