The island of Pantelleria represents the emerging tip of a volcanic complex of which about 28% has emerged, while the remaining 72% is located below sea level, up to a depth of about 1200 m. The birth of the volcano is linked to the formation of a large area of distensive in the Strait of Sicily with NO-SE trend. This "rifting" has been active since the Late Miocene and accompanied by widespread volcanic activity mainly concentrated in the NW area of the Strait of Sicily.
