To model this earthquake from teleseismic records, we used a potency density tensor inversion, which projects multiple fault slips onto a single model fault plane, reducing the non-uniqueness due to the uncertainty in selecting the faults’ orientations. The resulting distribution of potency-rate density tensors is consistent with observed surface ruptures. In its initial stage, the rupture propagated northeastward primarily at shallow depths. Later, the rupture propagated northeastward at greater depths beneath a gap in reported surface ruptures. The main rupture phase started in the northeastern part of the Kekerengu fault after 50 s and propagated bilaterally to the northeast and southwest. The non-double-couple component grew to a large fraction of the source elements as the rupture went through the junction of the Jordan Thrust and the Papatea fault, which suggests that the rupture branched into both faults as it back-propagated toward the southwest. The potency density tensor inversion sheds new light on the irregular evolution of this earthquake, which produced a fault rupture pattern of unprecedented complexity. Our source model of the 2016 Kaikoura earthquake (e.g., back-rupture propagation) could prompt research to determine a more realistic model with segmented faults using near-field data.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380021390573524766","@type":"Researcher","foaf:name":[{"@value":"Kenta Ohara"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021390573524874","@type":"Researcher","foaf:name":[{"@value":"Yuji Yagi"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021390573524864","@type":"Researcher","foaf:name":[{"@value":"Shinji Yamashita"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021390573524739","@type":"Researcher","foaf:name":[{"@value":"Ryo Okuwaki"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021390573524776","@type":"Researcher","foaf:name":[{"@value":"Shiro Hirano"}]},{"@id":"https://cir.nii.ac.jp/crid/1380021390573524750","@type":"Researcher","foaf:name":[{"@value":"Yukitoshi Fukahata"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"21974284"}],"prism:publicationName":[{"@value":"Progress in Earth and Planetary Science"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2023-07-10","prism:volume":"10","prism:number":"1"},"reviewed":"false","dc:rights":["https://creativecommons.org/licenses/by/4.0","https://creativecommons.org/licenses/by/4.0"],"url":[{"@id":"https://link.springer.com/content/pdf/10.1186/s40645-023-00565-z.pdf"},{"@id":"https://link.springer.com/article/10.1186/s40645-023-00565-z/fulltext.html"}],"createdAt":"2023-07-10","modifiedAt":"2023-07-10","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Waveform%20inversion","dc:title":"Waveform inversion"},{"@id":"https://cir.nii.ac.jp/all?q=QE1-996.5","dc:title":"QE1-996.5"},{"@id":"https://cir.nii.ac.jp/all?q=Earthquake%20source%20observation","dc:title":"Earthquake source observation"},{"@id":"https://cir.nii.ac.jp/all?q=Geology","dc:title":"Geology"},{"@id":"https://cir.nii.ac.jp/all?q=G","dc:title":"G"},{"@id":"https://cir.nii.ac.jp/all?q=Earthquake%20dynamics","dc:title":"Earthquake dynamics"},{"@id":"https://cir.nii.ac.jp/all?q=Body%20waves","dc:title":"Body waves"},{"@id":"https://cir.nii.ac.jp/all?q=Geography.%20Anthropology.%20Recreation","dc:title":"Geography.
