Several Bouguer anomaly surveys are available for this area with different resolution and accuracy; gravity data derive from the integration of stations placed below and above the sea level as the caldera develops both onshore and offshore. The comparison of these maps with the Digital Elevation Model shows a still remaining Terrain Effect hiding the shallower and deep caldera structure\u2019s signal. This effect has an impact on the modelling of the gravity source\u2019s depth and geometry. In this research, we apply a geologically constrained terrain correction method to the higher resolution Free Air dataset available for the study area to enhance the complete Bouguer reduction. The correlation analysis between the residual and the topography allows us to assess the quality of the outcomes. The results represent an improvement in the anomalies\u2019 isolation and clearly show a continuous circular-like clustering of maxima related to the geometry of the caldera rim. The minima are associated with volcano-tectonic depression filled with pyroclastic and sediment. Furthermore, features alignments overlap the fault systems, along which the volcanic activity occurred.<\/jats:p>","DOI":"10.3390\/rs15010209","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T02:44:03Z","timestamp":1672627443000},"page":"209","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Bouguer Anomaly Re-Reduction and Interpretative Remarks of the Phlegraean Fields Caldera Structures (Southern Italy)"],"prefix":"10.3390","volume":"15","author":[{"given":"Riccardo","family":"De Ritis","sequence":"first","affiliation":[{"name":"National Institute of Geophysics and Volcanology (INGV), Environment Department-Roma 2, 00143 Roma, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7835-1116","authenticated-orcid":false,"given":"Luca","family":"Cocchi","sequence":"additional","affiliation":[{"name":"National Institute of Geophysics and Volcanology (INGV), Environment Department-Roma 2, 00143 Roma, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3045-9002","authenticated-orcid":false,"given":"Salvatore","family":"Passaro","sequence":"additional","affiliation":[{"name":"ISMAR-CNR National Research Council of Italy, 80133 Naples, Italy"}]},{"given":"Thomas","family":"Campagne","sequence":"additional","affiliation":[{"name":"Mira Geoscience Ltd., Vancouver, BC V6C 1T2, Canada"}]},{"given":"Gianluca","family":"Gabriellini","sequence":"additional","affiliation":[{"name":"Eni Spa\u2014Natural Resources, San Donato Milanese, 20097 Milan, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"953","DOI":"10.1007\/s00410-013-0953-7","article-title":"Crystallization and eruption ages of Breccia Museo (Campi Flegrei caldera, Italy) plutonic clasts and their relation to the Campanian ignimbrite","volume":"167","author":"Gebauer","year":"2014","journal-title":"Contrib.
