Yet, little is known about the early stage, i.e., from minutes to hours after the mainshock. Its detailed study requires continuous high-rate position time series close to the fault, and advanced signal processing to accurately extract the surface displacements. Here, we use refined kinematic precise point positioning processing to document the early postseismic deformation for three earthquakes along the South American subduction zone (2010 M<jats:sub><jats:italic>w</jats:italic></jats:sub>8.8 Maule, Chile; 2015 M<jats:sub><jats:italic>w</jats:italic></jats:sub>8.3 Illapel, Chile; 2016 M<jats:sub><jats:italic>w</jats:italic></jats:sub>7.6 Pedernales, Ecuador). First, we show that early afterslip generates significant surface displacement as early as a few tens of minutes after the earthquake. Our analysis of the time series indicates that, over the first 36 hours, more than half of the displacement occurs within the first 12 hours, a time window often disregarded with daily positioning. Thus, estimates of coseismic offsets can be biased by more than 10% if early postseismic displacements are acknowledged as coseismic ones. Finally, these results highlight the difficulty to accurately evaluate the different contribution to the seismic cycle budget and thus the associated hazard on faults.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382262944737305473","@type":"Researcher","foaf:name":[{"@value":"Cedric Twardzik"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944737305472","@type":"Researcher","foaf:name":[{"@value":"Mathilde Vergnolle"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944737305475","@type":"Researcher","foaf:name":[{"@value":"Anthony Sladen"}]},{"@id":"https://cir.nii.ac.jp/crid/1382262944737305474","@type":"Researcher","foaf:name":[{"@value":"Antonio Avallone"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"20452322"}],"prism:publicationName":[{"@value":"Scientific Reports"}],"dc:publisher":[{"@value":"Springer Science and Business Media LLC"}],"prism:publicationDate":"2019-02-11","prism:volume":"9","prism:number":"1","prism:startingPage":"1775"},"reviewed":"false","dc:rights":["https://creativecommons.org/licenses/by/4.0","https://creativecommons.org/licenses/by/4.0"],"url":[{"@id":"https://www.nature.com/articles/s41598-019-39038-z.pdf"},{"@id":"https://www.nature.com/articles/s41598-019-39038-z"}],"createdAt":"2019-02-11","modifiedAt":"2024-07-14","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360017282190564608","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Imaging evolution of Cascadia slow-slip event using high-rate GPS"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892106671616","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"On the performance of position-domain sidereal filter for 30-s kinematic GPS to mitigate multipath errors"}]},{"@id":"https://cir.nii.ac.jp/crid/2050870367075046400","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Adjoint-based direct data assimilation of GNSS time series for optimizing frictional parameters and predicting postseismic deformation following the 2003 Tokachi-oki earthquake"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1038/s41598-019-39038-z"},{"@type":"CROSSREF","@value":"10.1038/s41598-022-10957-8_references_DOI_OgBBBBQ3bRgVdAu6ymBgVImsaR3"},{"@type":"CROSSREF","@value":"10.1186/s40623-022-01584-8_references_DOI_OgBBBBQ3bRgVdAu6ymBgVImsaR3"},{"@type":"CROSSREF","@value":"10.1186/s40623-020-01293-0_references_DOI_OgBBBBQ3bRgVdAu6ymBgVImsaR3"}]}
