History of vulcanism in the Napoli region. Three geological phases or periods are recognised and distinguished. The First Phlegraean Period. It is thought that the eruption of the Archiflegreo volcano occurred about 37,000 years ago, erupting about 200 cu km (48 cu mi) of magma to produce the Campanian Ignimbrite. (a VEI 7 eruption) The Second Phlegraean Period. Between the 35,000-10,500 years ago, it is characterized by the yellow tuff that constitutes the rests of an immense underwater volcano (having a diameter of approx 15 km (9.3 mi) Approximately 12,000 years ago the last major eruption occurred, forming a smaller caldera inside the main one, centered on the town of Pozzuoli. This event produced the Neopolitan yellow tuff, referring to the characteristic yellow rocks there. The Third Phlegraean Period. Dated between 8,000 - 500 years ago, it is characterized by white pozzolana, the material that forms the majority of volcanoes in Flegrei Fields. Broadly speaking, it can be said there was an initial activity to the south-west in the zone of Bacoli and Baiae (10,000-8000 years ago); an intermediate activity in an area centered between Pozzuoli, Spaccata Mountain and Agnano (8000-3900 years ago); and a more recent activity, moved towards the west to form Lake Avernus and Monte Nuovo (New Mountain) (3800-500 years ago). includes eruption of Mount Vesuvius 79 AD eruption (VEI 5)
