This study presents the first resistivity model of the Travale geothermal field derived from derivative-based 3D MT inversion. We analyzed MT data that have been acquired in Travale over the past decades in order to determine its geoelectrical dimensionality, directionality, and phase tensor properties. We selected data from 51 MT sites for 3D inversion. We carried out a number of 3D MT inversion tests by changing the type of data to be inverted, the inclusion of static-shift correction at some sites where new time-domain electromagnetic soundings (TDEM) were acquired, the grid rotation, as well as the starting model in order to assess the connection between the inversion model and the geology. The final 3D model herein presents deep elongated resistive bodies between the depths of 1.5 and 8 km. They are transverse to the Apennine structures and suggest a correlation with the strike-slip tectonics. Comparison with a seismic velocity model and well log data suggests a highly-fractured volume of rocks with vapor-dominated circulation. The outcome of this study provides new insights into the complex geothermal system of Travale.<\/jats:p>","DOI":"10.3390\/rs14030542","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T21:07:11Z","timestamp":1643144831000},"page":"542","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Three-Dimensional Magnetotelluric Characterization of the Travale Geothermal Field (Italy)"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8415-6894","authenticated-orcid":false,"given":"Francesca","family":"Pace","sequence":"first","affiliation":[{"name":"Department of Environment, Land and Infrastructure Engineering (DIATI), Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9551-8069","authenticated-orcid":false,"given":"Anna","family":"Mart\u00ed","sequence":"additional","affiliation":[{"name":"Departament de Din\u00e0mica de la Terra i de l\u2019Oce\u00e0, Facultat de Ci\u00e8ncies de la Terra, Institut Geomodels, Universitat de Barcelona, C\/Mart\u00ed i Franqu\u00e8s s\/n, 08028 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4195-4228","authenticated-orcid":false,"given":"Pilar","family":"Queralt","sequence":"additional","affiliation":[{"name":"Departament de Din\u00e0mica de la Terra i de l\u2019Oce\u00e0, Facultat de Ci\u00e8ncies de la Terra, Institut Geomodels, Universitat de Barcelona, C\/Mart\u00ed i Franqu\u00e8s s\/n, 08028 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3895-9324","authenticated-orcid":false,"given":"Alessandro","family":"Santilano","sequence":"additional","affiliation":[{"name":"Institute of Geosciences and Earth Resources\u2014National Research Council (IGG-CNR), Via Moruzzi 1, 56124 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2367-0969","authenticated-orcid":false,"given":"Adele","family":"Manzella","sequence":"additional","affiliation":[{"name":"Institute of Geosciences and Earth Resources\u2014National Research Council (IGG-CNR), Via Moruzzi 1, 56124 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juanjo","family":"Ledo","sequence":"additional","affiliation":[{"name":"Departament de Din\u00e0mica de la Terra i de l\u2019Oce\u00e0, Facultat de Ci\u00e8ncies de la Terra, Institut Geomodels, Universitat de Barcelona, C\/Mart\u00ed i Franqu\u00e8s s\/n, 08028 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Godio","sequence":"additional","affiliation":[{"name":"Department of Environment, Land and Infrastructure Engineering (DIATI), Politecnico di Torino, Corso Duca degli Abruzzi 24, 10129 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1190\/1.1443931","article-title":"A numerical evaluation of electromagnetic methods in geothermal exploration","volume":"61","author":"Pellerin","year":"1996","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"459","DOI":"10.1016\/j.jappgeo.2008.05.007","article-title":"Electromagnetic sounding of geothermal zones","volume":"68","author":"Spichak","year":"2009","journal-title":"J.
