Acoustic shockwaves from meteoroid ablation convert to infrasound and seismic energy, enabling fireball detection using seismoacoustic methods. We analyzed an unreported fireball in 2022 near the Azores, recorded by 26 seismometers and two infrasound arrays. Through polarization analyses, array methods, and 3\u2010D ray\u2010tracing, we determined that the terminal blast occurred at 40\u00a0km altitude, \u223c60\u00a0km NE of S\u00e3o Miguel Island. This location matches an unidentified flash captured by a lightning detector aboard the GOES\u201016 satellite. The estimated kinetic energy is \u223c10<jats:sup>\u22123<\/jats:sup>\u00a0kT TNT equivalent, suggesting a 10<jats:sup>\u22121<\/jats:sup>\u00a0m object diameter, thousands of which enter the atmosphere annually. Our results demonstrate how geophysical methods, in tandem with satellite data, can significantly improve the observational completeness of meteoroids, advancing our understanding of their sources and entry processes.<\/jats:p>","DOI":"10.1029\/2023gl105773","type":"journal-article","created":{"date-parts":[[2023,11,14]],"date-time":"2023-11-14T17:34:20Z","timestamp":1699983260000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Exclusive Seismoacoustic Detection and Characterization of an Unseen and Unheard Fireball Over the North Atlantic"],"prefix":"10.1029","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7476-3284","authenticated-orcid":false,"given":"Stephen P.","family":"Hicks","sequence":"first","affiliation":[{"name":"Department of Earth Sciences University College London  London UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8406-7856","authenticated-orcid":false,"given":"Sandro B.","family":"Matos","sequence":"additional","affiliation":[{"name":"Instituto de Investiga\u00e7\u00e3o em Vulcanologia e Avalia\u00e7\u00e3o de Riscos (IVAR) Universidade dos A\u00e7ores  Azores Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6954-387X","authenticated-orcid":false,"given":"Adriano","family":"Pimentel","sequence":"additional","affiliation":[{"name":"Instituto de Investiga\u00e7\u00e3o em Vulcanologia e Avalia\u00e7\u00e3o de Riscos (IVAR) Universidade dos A\u00e7ores  Azores Portugal"},{"name":"Centro de Informa\u00e7\u00e3o e Vigil\u00e2ncia Sismovulc\u00e2nica dos A\u00e7ores (CIVISA)  Azores Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3330-9322","authenticated-orcid":false,"given":"Giacomo","family":"Belli","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze della Terra Universit\u00e0 degli Studi di Firenze  Firenze Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1554-7845","authenticated-orcid":false,"given":"Duccio","family":"Gheri","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze della Terra Universit\u00e0 degli Studi di Firenze  Firenze Italy"}]},{"given":"Maria","family":"Tsekhmistrenko","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences University College London  London UK"}]},{"given":"Kasra","family":"Hosseini","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences University College London  London UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6807-555X","authenticated-orcid":false,"given":"Wolfram H.","family":"Geissler","sequence":"additional","affiliation":[{"name":"Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research  Bremerhaven Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5538-162X","authenticated-orcid":false,"given":"Rita","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto de Investiga\u00e7\u00e3o em Vulcanologia e Avalia\u00e7\u00e3o de Riscos (IVAR) Universidade dos A\u00e7ores  Azores Portugal"},{"name":"Centro de Informa\u00e7\u00e3o e Vigil\u00e2ncia Sismovulc\u00e2nica dos A\u00e7ores (CIVISA)  Azores Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1689-5067","authenticated-orcid":false,"given":"Nicolau","family":"Wallenstein","sequence":"additional","affiliation":[{"name":"Instituto de Investiga\u00e7\u00e3o em Vulcanologia e Avalia\u00e7\u00e3o de Riscos (IVAR) Universidade dos A\u00e7ores  Azores Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9492-6415","authenticated-orcid":false,"given":"Ana M.
