However, it is puzzling that the largest Tohoku tsunami heights occurred about 100 km north of the largest slip zone, where bathymetric surveys indicate no large slip at the trench or submarine landslides. Here we show that coseismic yielding of plentiful sediments in the northern Japan Trench margin can induce large inelastic uplift landward from the trench and diminish slip near the trench. The scarcity of sediments in the south leads to nearly elastic response with large slip at the trench and mostly horizontal seafloor displacement. Thus, the variations of sediments along the Japan Trench and sediment yielding can explain the puzzling variations of tsunamigenesis and near‐trench slip in this earthquake. Inelastic wedge deformation can be an important mechanism of tsunamigenesis in accretionary and other sediment‐filled plate margins.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845655035137","@type":"Researcher","foaf:name":[{"@value":"Shuo Ma"}],"jpcoar:affiliationName":[{"@value":"Department of Geological Sciences San Diego State University  San Diego CA USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845655035136","@type":"Researcher","foaf:name":[{"@value":"Shiying Nie"}],"jpcoar:affiliationName":[{"@value":"Department of Geological Sciences San Diego State University  San Diego CA USA"}]}],"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":"2019-08-16","prism:volume":"46","prism:number":"15","prism:startingPage":"8782","prism:endingPage":"8790"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://onlinelibrary.wiley.com/doi/pdf/10.1029/2019GL083148"},{"@id":"https://onlinelibrary.wiley.com/doi/full-xml/10.1029/2019GL083148"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2019GL083148"}],"createdAt":"2019-07-30","modifiedAt":"2024-05-25","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360853567814702080","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Extracting Near‐Field Seismograms From Ocean‐Bottom Pressure Gauge Inside the Focal Area: Application to the 2011 Mw 9.1 Tohoku‐Oki Earthquake"}]},{"@id":"https://cir.nii.ac.jp/crid/1360857593727289600","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Impulsive Tsunami and Large Runup Along the Sanriku Coast of Japan Produced by an Inelastic Wedge Deformation Model"}]},{"@id":"https://cir.nii.ac.jp/crid/1360865815502303360","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"New source model for the 1771 Meiwa tsunami along the southern Ryukyu Trench inferred from high-resolution tsunami calculation"}]},{"@id":"https://cir.nii.ac.jp/crid/1361694371173476992","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Tsunami Modeling for the Deep Sea and Inside Focal Areas"}]},{"@id":"https://cir.nii.ac.jp/crid/2051433317043076096","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A new mechanical perspective on a shallow megathrust near-trench slip from the high-resolution fault model of the 2011 Tohoku-Oki earthquake"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2019gl083148"},{"@type":"CROSSREF","@value":"10.1029/2021jb022098_references_DOI_RhgHhj0dFIrCeqhMa3bfJPlkcRC"},{"@type":"CROSSREF","@value":"10.1186/s40645-022-00524-0_references_DOI_2moHaCLzZ1XGMKCrk5hjf60o0TU"},{"@type":"CROSSREF","@value":"10.1029/2020gl091664_references_DOI_2moHaCLzZ1XGMKCrk5hjf60o0TU"},{"@type":"CROSSREF","@value":"10.1186/s40645-024-00631-0_references_DOI_2moHaCLzZ1XGMKCrk5hjf60o0TU"},{"@type":"CROSSREF","@value":"10.1146/annurev-earth-071719-054845_references_DOI_2moHaCLzZ1XGMKCrk5hjf60o0TU"}]}
