In the opening chapter of this compilation, the authors process and geologically interpretate the marine geological mapping of a detailed grid of very high resolution seismic profiles recorded in the Campania continental shelf between the Solofrone river mouth and Agnone. Following this, an integrated analysis of the volcanic structures located in the subsurface of Naples and the Gulf of Gaeta is presented based on the geologic interpretation of seismic profiles. The goal of this study is to advance the seismo-stratigraphic knowledge concerning volcanic structures occurring in this sector of...
