The Campanian Volcanic Arc is a volcanic region located in southern Italy, primarily in the Campania region. It includes several active volcanoes, such as Mount Vesuvius, Campi Flegrei, and Ischia. This area is known for its complex geological activity, resulting from the subduction of the African Plate beneath the Eurasian Plate. The volcanic arc has a rich history of eruptions, with Mount Vesuvius being famous for its catastrophic eruption in 79 AD that buried the cities of Pompeii and Herculaneum. The region's volcanic activity continues to pose risks to nearby populations, making monitoring and research essential for safety and understanding geological processes.
