The broadband P‐wave ground displacement records show the presence of several distinct phases whose relative amplitudes vary among the stations. We perform very broadband waveform analyses over four different frequency bands: CMT inversion (surface waves (4∼5mHz) and long‐period body waves (12∼20mHz)), waveform inversion using the long‐period P, pP and SH waves (∼0.04Hz), and broadband P‐ and pP‐wave waveform analysis (0.03∼1Hz). We show that the large non double couple solution observed at long periods (>25 sec) is very likely to be a manifestation of the presence of subevents with different double couple mechanisms in a single rupture sequence.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380292619200528513","@type":"Researcher","foaf:name":[{"@value":"Keiko Kuge"}]},{"@id":"https://cir.nii.ac.jp/crid/1380292619200528512","@type":"Researcher","foaf:name":[{"@value":"Hitoshi Kawakatsu"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1990-03","prism:volume":"17","prism:number":"3","prism:startingPage":"227","prism:endingPage":"230"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2FGL017i003p00227"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/GL017i003p00227"}],"createdAt":"2008-02-06","modifiedAt":"2023-09-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050001335849268224","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Mathematical review on source-type diagrams"}]},{"@id":"https://cir.nii.ac.jp/crid/1360306905621680256","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Impact of the Offshore Seismograph Network and 3‐D Seismic Velocity Structure Model on Centroid Moment Tensor Analysis for Offshore Earthquakes: Application to the Japan Trench Subduction Zone"}]},{"@id":"https://cir.nii.ac.jp/crid/1360584340530873856","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Complex rupture evolution of the 2007 Martinique earthquake: a non-double-couple event in the Caribbean Sea"}]},{"@id":"https://cir.nii.ac.jp/crid/1360588381081039616","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Characterizing Lithospheric Transverse Isotropy Using Moment Tensors—On the Origin of the Non–Double-Couple Components of Global CMT Solutions"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846639279867264","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Source analysis of a potential hydraulic‐fracturing‐induced earthquake near Fox Creek, Alberta"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/gl017i003p00227"},{"@type":"OPENAIRE","@value":"doi_dedup___::76a148fcc2e7ca3fd5944cfaf02bce87"},{"@type":"CROSSREF","@value":"10.1029/2024jb029944_references_DOI_3URb0iZf4InoLbRJjBq4IQOGeFw"},{"@type":"CROSSREF","@value":"10.1186/s40623-016-0421-5_references_DOI_3URb0iZf4InoLbRJjBq4IQOGeFw"},{"@type":"CROSSREF","@value":"10.1093/gji/ggae024_references_DOI_3URb0iZf4InoLbRJjBq4IQOGeFw"},{"@type":"CROSSREF","@value":"10.1785/0120240136_references_DOI_3URb0iZf4InoLbRJjBq4IQOGeFw"},{"@type":"CROSSREF","@value":"10.1002/2015gl066917_references_DOI_3URb0iZf4InoLbRJjBq4IQOGeFw"}]}
