Here we examine the aftershock sequence recorded during the first 32 days following the 2007 Noto-Hanto earthquake, Japan. By applying a matched-filter technique to the data, we detected about 10 times more events than those listed in the routinely constructed earthquake catalog. The aftershock area expanded along the fault strike as a logarithmic function of time, beginning immediately after the main shock. Aftershock expansion toward the SW was especially extensive and developed more rapidly than toward the NE. Interestingly, the aftershock area expanded in a step-like manner by the activation of a series of spatially clustered seismic bursts. Spatial correlation between the aftershock extension and the afterslip distribution suggests that the expansion of the aftershock area could be mainly driven by aseismic afterslip. The aftershock area continues to expand, even though 7 years have now passed since the main shock."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319091656961","@type":"Researcher","foaf:name":[{"@value":"Aitaro Kato"}],"jpcoar:affiliationName":[{"@value":"Earthquake and Volcano Research Center, Graduate School of Environmental Studies; Nagoya University; Nagoya Japan"},{"@value":"Earthquake Research Institute; University of Tokyo; Tokyo Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319091656960","@type":"Researcher","foaf:name":[{"@value":"Kazushige Obara"}],"jpcoar:affiliationName":[{"@value":"Earthquake Research Institute; University of Tokyo; Tokyo Japan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2014-06-13","prism:volume":"41","prism:number":"11","prism:startingPage":"3864","prism:endingPage":"3869"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["http://doi.wiley.com/10.1002/tdm_license_1","http://onlinelibrary.wiley.com/termsAndConditions"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F2014GL060427"},{"@id":"http://onlinelibrary.wiley.com/wol1/doi/10.1002/2014GL060427/fullpdf"}],"createdAt":"2014-05-31","modifiedAt":"2018-04-02","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004233291525504","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Why Do Aftershocks Occur Within the Rupture Area of a Large Earthquake?"}]},{"@id":"https://cir.nii.ac.jp/crid/1360023718186912256","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Implications of Fault‐Valve Behavior From Immediate Aftershocks Following the 2023 <i>M</i><sub><i>j</i></sub>6.5 Earthquake Beneath the Noto Peninsula, Central Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360565164303904640","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Foreshock migration preceding the 2016 <i>M<sub>w</sub></i> 7.0 Kumamoto earthquake, Japan"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567183245123584","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Seismic Evidence of an Early Afterslip During the 2012 Sequence in Emilia (Italy)"}]},{"@id":"https://cir.nii.ac.jp/crid/1360869459052787584","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Coseismic Slip and Early Afterslip of the 2024 Hyuganada Earthquake Modulated by a Subducted Seamount"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282679122034944","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"The 2016 Kumamoto earthquake sequence"}]},{"@id":"https://cir.nii.ac.jp/crid/2050307417129953664","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Detection of low-frequency earthquakes by the matched filter technique using the product of mutual information and correlation coefficient"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/2014gl060427"},{"@type":"OPENAIRE","@value":"doi_dedup___::81c1c3a3af5a9b67938cdc3021912ccc"},{"@type":"CROSSREF","@value":"10.1029/2018gl077843_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.1186/s40623-021-01534-w_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.1029/2024gl112826_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.1029/2023gl106444_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.1002/2016gl070079_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.1029/2018gl079617_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"},{"@type":"CROSSREF","@value":"10.2183/pjab.92.359_references_DOI_npJPI7mrpiZqC4yPBY9Kg96062"}]}
