We calculate rupture propagation using an elastodynamic boundary integral equation method (BIEM) in which the trajectory of a fault tip is dynamically self‐chosen. We consider a system of two noncoplanar fault segments: a preexisting main fault segment (fault 1) and a subsidiary one (fault 2) and, allowing the tip of fault 2 to deviate from its original plane, trace its trajectory in the step over region between the two fault segments. Our simulation results show that the final geometry of fault 2 depends on the initial configuration of the two fault segments. If the initial overlap of the two fault segments is smaller than the half length of fault 1, fault 2 coalesces with fault 1 when the step over is narrower than about 1/4–1/2 the length of the latter but is repelled from fault 1 when the step over width is larger than this threshold value. We also show that the inclination angle of fault 2 is sensitive to the rupture velocity; the inclination is larger for faster rupture propagation. Our simulation results imply that as ruptures occur repeatedly, a fault system evolves from an array of relatively small fault segments into a sequence of larger ones. Our results seem consistent with the field observations of natural fault system geometries, which are often characterized by a set of noncoplanar segments interconnected with relatively small jogs at oblique angles.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388845135315842","@type":"Researcher","foaf:name":[{"@value":"Ryosuke Ando"}],"jpcoar:affiliationName":[{"@value":"Earthquake Research Institute University of Tokyo  Tokyo Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845135315841","@type":"Researcher","foaf:name":[{"@value":"Taku Tada"}],"jpcoar:affiliationName":[{"@value":"Department of Architecture, Faculty of Engineering Tokyo University of Science  Tokyo Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1383388845135315840","@type":"Researcher","foaf:name":[{"@value":"Teruo Yamashita"}],"jpcoar:affiliationName":[{"@value":"Earthquake Research Institute University of Tokyo  Tokyo Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2004-05","prism:volume":"109","prism:number":"B5","prism:startingPage":"363"},"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%2F2003JB002665"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2003JB002665"}],"createdAt":"2004-05-17","modifiedAt":"2023-10-12","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050850092121518848","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Comparison of two time-marching schemes for dynamic rupture simulation with a space-domain BIEM"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001204303059968","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Numerical Simulation on Faulting: Microscopic Evolution, Macroscopic Interaction and Rupture Process of Earthquakes"},{"@language":"ja","@value":"断層の成長"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2003jb002665"},{"@type":"OPENAIRE","@value":"doi_dedup___::9e86a0ef50a0a3d0354f470ba7c97145"},{"@type":"CROSSREF","@value":"10.4294/zisin.61.403_references_DOI_a6BleE4hH9QAUtHfkv9OViU9OZV"},{"@type":"CROSSREF","@value":"10.1186/s40623-020-01202-5_references_DOI_a6BleE4hH9QAUtHfkv9OViU9OZV"}]}
