Submarine Stratigraphy of the Eastern Bay of Naples: New Seismo-Stratigraphic Data and Implications for the Somma-Vesuvius and Campi Flegrei Volcanic Activity

The submarine stratigraphy of the eastern Bay Naples is studied through seismo-stratigraphic data correlated with borehole data. Multichannel seismic profiles are interpreted in order to reconstruct stratigraphic relationships between Quaternary marine units and volcanic acoustic substratum. Seven recognized based on geological interpretation using criteria. top lowest unit was Campanian Ignimbrite (Southern Campania Volcanic Zone). setting characterized by NE-SW trending structures, probably corresponding tuff rings. These rings can be compared Porto Miseno, Archiaverno Averno, Astroni (Campi Flegrei). Offshore, Somma-Vesuvius a as fallout deposits representing base AD 79 eruption. However, since branch isopach 5 m “Pomici di Avellino” pyroclastic very close Tyrrhenian coastline near our GRNA01 GRNA03 profiles, we cannot exclude that could also this
