BackgroundThe Gaeta Bay Volcanic Field consists of a group of eight buried submarine volcanoes of Middle to Lower Pleistocene age (Torrente and Milia, 2013). This volcanism is generally characterized by thick lava flows and volcaniclastic deposits. The entire volcanic field is up to 1500 m thick. Volcanic activity in the Gaeta Bay and surrounding regions was largely fault bounded, where extension and subsidence controlled the emplacement and displacement of most of the volcanic centers (Torrente and Milia, 2013). These volcanic centers developed between 0.4 and 0.1 Ma. The oldest volcanic center is lower Pleistocene. The extension and volcanism responsible for the volcanic field migrated eastward with time, towards the Campi Flegrei (Torrente and Milia, 2013).
