The 40 Ar- 39 Ar ages on feldspar phenocrysts yielded ages of c. 16 ka and 22 ka for events older than the Neapolitan Yellow Tuff caldera-forming eruption (15 ka), and ages of c. 40 ka, 53 ka and 78 ka for events older than the Campanian Ignimbrite caldera-forming eruption (39 ka). The oldest age obtained is 18 ka older than previous dates.

The last major eruption from the Campi Flegrei was the Neapolitan Yellow Tuff (NYT) that burst forth from the volcano ~15,000 years ago. This was preceded by an even bigger explosive eruption that happened ~39,000 years ago called the Campanian Ignimbrite, which may have had a hand in the downfall of the Neanderthals..

the Neapolitan Yellow Tuff (NYT) (12 ka BP) is considered to be the product of a single eruption. Two different members (A and B) have been identified and can be correlated around the whole of Campi Flegrei. Member A is made up of at least 6 fall units including both ash and lapilli horizons.

The results of a detailed stratigraphical and volcanological study has allowed the definition of the Neapolitan Yellow Tuff (NYT) as the largest known trachytic phreatoplinian eruption with an estimated volume of not less than 30 km 3 DRE. The NYT sequence can be subdivided in a lower and an upper member.
