For example, during the 2015 <jats:italic>M</jats:italic>7.8 Gorkha earthquake, Nepal, a slip pulse propagating along strike unzipped the bottom edge of the locked portion of the Main Himalayan Thrust (MHT). The lower edge of the rupture produced dominant high‐frequency (>1 Hz) radiation of seismic waves. We show that similar partial ruptures occur spontaneously in a simple dynamic model of earthquake sequences. The fault is governed by standard laboratory‐based rate‐and‐state friction with the aging law and contains one homogenous velocity‐weakening (VW) region embedded in a velocity‐strengthening (VS) area. Our simulations incorporate inertial wave‐mediated effects during seismic ruptures (they are thus fully dynamic) and account for all phases of the seismic cycle in a self‐consistent way. Earthquakes nucleate at the edge of the VW area and partial ruptures tend to stay confined within this zone of higher prestress, producing pulse‐like ruptures that propagate along strike. The amplitude of the high‐frequency sources is enhanced in the zone of higher, heterogeneous stress at the edge of the VW area.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388846173609473","@type":"Researcher","foaf:name":[{"@value":"Sylvain Michel"}],"jpcoar:affiliationName":[{"@value":"Bullard Laboratories, Department of Earth Sciences University of Cambridge  Cambridge UK"},{"@value":"Division of Geological and Planetary Sciences California Institute of Technology  Pasadena California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846173609472","@type":"Researcher","foaf:name":[{"@value":"Jean‐Philippe Avouac"}],"jpcoar:affiliationName":[{"@value":"Division of Geological and Planetary Sciences California Institute of Technology  Pasadena California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846173609474","@type":"Researcher","foaf:name":[{"@value":"Nadia Lapusta"}],"jpcoar:affiliationName":[{"@value":"Division of Geological and Planetary Sciences California Institute of Technology  Pasadena California USA"},{"@value":"Division of Engineering and Applied Science California Institute of Technology  Pasadena California USA"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388846173609475","@type":"Researcher","foaf:name":[{"@value":"Junle Jiang"}],"jpcoar:affiliationName":[{"@value":"Institute of Geophysics and Planetary Physics, Scripps Institution of Oceanography University of California, San Diego  La Jolla California 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":"2017-08-28","prism:volume":"44","prism:number":"16","prism:startingPage":"8345","prism:endingPage":"8351"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#am","http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F2017GL074725"},{"@id":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/2017GL074725"},{"@id":"https://onlinelibrary.wiley.com/doi/full-xml/10.1002/2017GL074725"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/am-pdf/10.1002/2017GL074725"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1002/2017GL074725"}],"createdAt":"2017-08-17","modifiedAt":"2023-09-09","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360290617436710528","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Back-propagating supershear rupture in the 2016 Mw 7.1 Romanche transform fault earthquake"}]},{"@id":"https://cir.nii.ac.jp/crid/1360857593724550144","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Community‐Driven Code Comparisons for Three‐Dimensional Dynamic Modeling of Sequences of Earthquakes and Aseismic Slip"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842049991168","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Structural control and system-level behavior of the seismic cycle at the Nankai Trough"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/2017gl074725"},{"@type":"CROSSREF","@value":"10.1038/s41561-020-0619-9_references_DOI_FfMrYepRUZUZCuiCmfBa5vArO7j"},{"@type":"CROSSREF","@value":"10.1029/2021jb023519_references_DOI_FfMrYepRUZUZCuiCmfBa5vArO7j"},{"@type":"CROSSREF","@value":"10.1186/s40623-020-1145-0_references_DOI_FfMrYepRUZUZCuiCmfBa5vArO7j"}]}
