{"doi":"10.1002/2016gl071140","title":"A three‐dimensional <i>Q<sub>P</sub></i> imaging of the shallowest subsurface of Campi Flegrei offshore caldera, southern Italy","abstract":"<jats:title>Abstract</jats:title><jats:p>To improve the knowledge of the shallowest subsurface of Campi Flegrei caldera, a 3‐D <jats:italic>P</jats:italic> wave attenuation tomography of the area was performed. We analyzed about 18,000 active seismic traces, which provided a data set of 11,873 Δ<jats:italic>t<jats:sup>*</jats:sup></jats:italic> measurements, e.g., the differential travel times to quality factor ratios. These were inverted through an adapted tomographic inversion procedure. The 3‐D tomographic images reveal an average <jats:italic>Q<jats:sub>P</jats:sub></jats:italic> about 70, interpreted as water‐saturated volcanic and marine sediments. An arc‐like, low‐<jats:italic>Q<jats:sub>P</jats:sub></jats:italic> structure at 0.5–1 km depths was interpreted as a densely fractured, fluid‐saturated rock volume, well matching the buried rim of Campi Flegrei caldera. The spatial distribution of high‐ and low‐<jats:italic>Q<jats:sub>P</jats:sub></jats:italic> bodies in the inner caldera is correlated with low‐<jats:italic>V<jats:sub>p</jats:sub></jats:italic> values and may reflect either the differences in the percentage of fluid saturation of sediments or the presence of vapor state fluids beneath fumarole manifestations.</jats:p>","journal":"Geophysical Research Letters","year":2016,"id":27970,"datarank":0.6719482747477865,"base_score":2.772588722239781,"endowment":2.772588722239781,"self_citation_contribution":0.41588830833596724,"citation_network_contribution":0.25605996641181933,"self_endowment_contribution":0.41588830833596724,"citer_contribution":0.25605996641181933,"corpus_percentile":70.30246770325675,"corpus_rank":3840,"citation_count":15,"citer_count":8,"citers_with_citation_signal":6,"citers_with_endowment":6,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":157910,"name":"Salvatore de Lorenzo","orcid":"0000-0003-2504-1485","position":1,"is_corresponding":false},{"id":157911,"name":"Guido Russo","orcid":"0000-0001-9268-8647","position":2,"is_corresponding":false},{"id":157912,"name":"Ortensia Amoroso","orcid":null,"position":3,"is_corresponding":false},{"id":157913,"name":"Stephane Garambois","orcid":null,"position":4,"is_corresponding":false},{"id":157914,"name":"Jean Virieux","orcid":"0000-0002-6201-1157","position":5,"is_corresponding":false},{"id":157915,"name":"Aldo Zollo","orcid":"0000-0002-8191-9566","position":6,"is_corresponding":false},{"id":157909,"name":"Vincenzo Serlenga","orcid":"0000-0001-8035-0892","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":2.70805020110221,"endowment":2.70805020110221,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24523987","pmcid":null,"openalex_id":"https://openalex.org/W2541854283","authors":[],"funders":[],"total_grants":0,"fwci":2.3032,"citation_percentile":0.86420391,"influential_citations":0,"citation_trend":[{"year":2017,"count":3},{"year":2018,"count":2},{"year":2019,"count":3},{"year":2022,"count":3},{"year":2023,"count":1},{"year":2024,"count":1},{"year":2026,"count":1}],"oa_status":"bronze","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/2016GL071140","host_type":"journal"},{"url":"https://agupubs.onlinelibrary.wiley.com/doi/pdfdirect/10.1002/2016GL071140","host_type":"BRONZE"},{"url":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/2016GL071140","host_type":"publisher"},{"url":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F2016GL071140","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/2016GL071140","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/full-xml/10.1002/2016GL071140","host_type":"publisher"},{"url":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2016GL071140","host_type":"publisher"},{"url":"https://doi.org/10.1002/2016gl071140","host_type":"journal"},{"url":"http://hdl.handle.net/11586/184009","host_type":"repository"}],"fields_of_study":["Seismic Imaging and Inversion Techniques","Seismic Waves and Analysis","earthquake and tectonic studies","Geology","Environmental Science"],"mesh_terms":[],"keywords":["Caldera","Fumarole","Geology","Volcano","Seismology","Submarine pipeline","Petrology","Mineralogy"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life below water"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-08T20:05:18.765215Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
