In the teleseismic P and SH wave‐forms, there are two distinctive wave packets that can be explained by multiple strike‐slip subevents. We propose a composite rupture model comprising two different episodes: two predominant clusters of en echelon strike‐slip segments (∼16 × 10<jats:sup>20</jats:sup> Nm) and normal faulting with a long duration of approximately 100 s (∼4 × 10<jats:sup>20</jats:sup> Nm). This model agrees with observations of both teleseismic body waves and long‐period surface waves, including the large non‐double‐couple component. The normal faulting with as long a duration as the main strike‐slip rupture might be secondarily induced by the en echelon segments of strike‐slip faulting.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825893884094978","@type":"Researcher","foaf:name":[{"@value":"Keiko Kuge"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825893884094977","@type":"Researcher","foaf:name":[{"@value":"Masayuki Kikuchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825893884094976","@type":"Researcher","foaf:name":[{"@value":"Yoshiko Yamanaka"}]}],"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":"1999-11-15","prism:volume":"26","prism:number":"22","prism:startingPage":"3401","prism:endingPage":"3404"},"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%2F1999GL005420"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/1999GL005420"}],"createdAt":"2002-09-17","modifiedAt":"2023-11-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004230175188736","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Seafloor structure near the epicenter of the great 25 March 1998 Antarctic Plate earthquake"}]},{"@id":"https://cir.nii.ac.jp/crid/2050025942122898304","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Dynamic rupture propagation on geometrically complex fault with along-strike variation of fault maturity : insights from the 2014 Northern Nagano earthquake"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/1999gl005420"},{"@type":"OPENAIRE","@value":"doi_dedup___::476c881417c9cd7076249b8d1b0f5f51"},{"@type":"CROSSREF","@value":"10.1186/s40623-017-0715-2_references_DOI_XokZIo6lq1Qu1SRK837YdxyMG84"},{"@type":"CROSSREF","@value":"10.1002/jgrb.50059_references_DOI_XokZIo6lq1Qu1SRK837YdxyMG84"}]}
