Malta is an archipelago in the central Mediterranean (in its eastern basin), some  from southern Italy across the Malta Channel. Only the three largest islands—Malta (Malta), Gozo (Għawdex), and Comino (Kemmuna)—are inhabited. The islands of the archipelago lie on the Malta plateau, a shallow shelf formed from the high points of a land bridge between Sicily and North Africa that became isolated as sea levels rose after the last Ice Age. The archipelago is located on the African tectonic plate.
