Building a bridge between distal tephra archives and the Neapolitan volcanoes: Insights on the 130-200 ka explosive activity from the Campanian Plain

The geological evidence of ancient activity of Neapolitan volcanic sources in southern Italy is often elusive and inaccessible in the proximal areas. In fact, these deposits are part of the thick pile of volcanic products alternating with alluvial/transitional/shallow marine sediments emplaced in the Campanian Plain over the last 2 Ma, which makes them often buried deep in the subsurface. Conversely, the distal and ultra-distal archives are rich in tephra layers attributed to "unknown eruptions
