The Campanian volcanic arc is a volcanic region located in southern Italy, primarily on the Campania region. It is part of the larger Apennine volcanic arc and includes notable volcanoes such as Mount Vesuvius, Campi Flegrei, and Ischia. This area is characterized by its complex geology and active volcanic processes, resulting from the subduction of the African tectonic plate beneath the Eurasian tectonic plate. The volcanic activity in the Campanian arc has shaped the landscape and influenced human settlement for centuries. Mount Vesuvius is particularly famous for its catastrophic eruption in 79 AD, which buried the cities of Pompeii and Herculaneum. Today, the region remains a focus of geological study and monitoring due to its potential for future eruptions.
