By stacking radial and transverse RFs with moveout perturbations, we estimate the downdip azimuth, dip angle, and depth of the slab Moho beneath each seismic station. Comparing the downdip azimuth to the slab convergence azimuth, we can classify the slab into three segments. The segments correspond to both the fault zones of past megathrust earthquakes and to the spatial distribution of intraslab seismicity. The slab Moho lies just above the intraslab seismicity in the southwestern Kii Peninsula. Slab Moho lies deeper at the eastern part of the peninsula, at the bottom of seismicity. This suggests that earthquakes occur only within the slab mantle under the southern Kii Peninsula. The dip angle of slab Moho becomes steeper at 40‐ to 50‐km depth, perhaps caused by dehydration transformation of basalt to eclogite. At some stations located in the western part of the Kii Peninsula, RF‐estimated dip angle of the interface is much steeper than that estimated by spatial trends in seismicity. Since the local seismicity distribution reflects well the larger‐scale geometry of the slab, the RF‐estimated dip angle may imply anisotropic wave speeds within strongly sheared and/or hydrated media around the slab Moho. These detailed features of the slab may be one key in distinguishing the source regions of megathrust earthquakes in the Nankai region.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825893934029569","@type":"Researcher","foaf:name":[{"@value":"Katsuhiko Shiomi"}],"jpcoar:affiliationName":[{"@value":"National Research Institute for Earth Science and Disaster Prevention  Tsukuba Japan"},{"@value":"Department of Geology and Geophysics Yale University  New Haven Connecticut USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1382825893934029568","@type":"Researcher","foaf:name":[{"@value":"Jeffrey Park"}],"jpcoar:affiliationName":[{"@value":"Department of Geology and Geophysics Yale University  New Haven Connecticut USA"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2008-10","prism:volume":"113","prism:number":"B10","prism:startingPage":"B10318"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2007JB005535"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2007JB005535"}],"createdAt":"2008-10-30","modifiedAt":"2023-10-13","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050855511197307776","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Seismological Structures on Bimodal Distribution of Deep Tectonic Tremor"}]},{"@id":"https://cir.nii.ac.jp/crid/1050866117150510336","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Deep plutonic bodies over low-frequency earthquakes revealed from receiver-side Green's functions"}]},{"@id":"https://cir.nii.ac.jp/crid/1360013168722329344","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Seismological evidence of a dehydration reaction in the subducting oceanic crust beneath western Shikoku in southwest Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360584339753569536","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Anisotropic Velocity Structure Beneath Shikoku, Japan: Insights From Receiver Function and Shear Wave Splitting Analyses"}]},{"@id":"https://cir.nii.ac.jp/crid/1360857596971023360","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Japan unified hIgh-resolution relocated catalog for earthquakes (JUICE): Crustal seismicity beneath the Japanese Islands"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282763073517952","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"水平動地震計特性の違いが地下構造推定に与える影響"},{"@language":"en","@value":"Effect on the Subsurface Structure Estimation by the Difference in Responses of Two Horizontal Component Seismographs"},{"@language":"ja-Kana","@value":"スイヘイドウ ジシンケイ トクセイ ノ チガイ ガ チカ コウゾウ スイテイ ニ アタエル エイキョウ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051714791869783424","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Dissimilar receiver functions observed at very close stations in the Kii Peninsula, central Japan : features and causes"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2007jb005535"},{"@type":"OPENAIRE","@value":"doi_dedup___::1edab302723af8627e163f2f7c288f60"},{"@type":"CROSSREF","@value":"10.1093/gji/ggaa423_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"},{"@type":"CROSSREF","@value":"10.1029/2020gl092183_references_DOI_Bm8XSTp4oKVLVqIeB5KiqJFHaEQ"},{"@type":"CROSSREF","@value":"10.1186/s40623-017-0631-5_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"},{"@type":"CROSSREF","@value":"10.1029/2023jb027178_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"},{"@type":"CROSSREF","@value":"10.1016/j.tecto.2017.02.017_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"},{"@type":"CROSSREF","@value":"10.1016/j.tecto.2024.230536_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"},{"@type":"CROSSREF","@value":"10.4294/zisin.2018-1_references_DOI_D4Otaaiiz4EKlbHcQwSJrikBawC"}]}
