Our simulation code uses the macroscopic governing equations derived by <jats:ext-link xmlns:xlink=\"http://www.w3.org/1999/xlink\" xlink:href=\"#jgrb12966-bib-0024\"><jats:italic>Pride</jats:italic> [1994]</jats:ext-link>, which couple Biot's theory and Maxwell equations via flux/force transport equations. In this theory the coupling mechanism is explained by electrokinetic effects taking place at the pore level. The synthetic seismoelectrograms and seismomagnetrograms are computed by extending the generalized reflection and transmission matrix method and by using a discrete wave number integration of the global reflectivity obtained in the frequency wave number domain. Synthetic time sections and snapshots of the wave propagation are used to study the seismic, electromagnetic, and seismoelectromagnetic waves properties in fluid‐saturated layered porous media. Two wave phenomena are investigated: (1) the electric and magnetic fields induced by the propagation of a seismic perturbation in a homogeneous porous medium and (2) the electromagnetic waves generated at depth when seismic waves propagate through a vertically heterogeneous porous medium. Concentrating on the second effect, we show that the zone which effectively contributes to the generation of EM disturbances along a plane interface coincides with the first Fresnel zone associated with a seismic‐to‐electromagnetic wave conversion. A numerical sensitivity study shows that the EM waves generated at depth by the passage of seismic waves through an interface are particularly sensitive to contrasts in porosity, permeability, fluid salinity, and fluid viscosity. Our numerical simulations highlight the potential of artificially generated seismoelectromagnetic converted waves for the characterization of the subsurface and its fluid content.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319114356096","@type":"Researcher","foaf:name":[{"@value":"Stéphane Garambois"}],"jpcoar:affiliationName":[{"@value":"Laboratoire de Geophysique Interne et de Tectonophysique Université Joseph Fourier and CNRS  Grenoble France"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319114356097","@type":"Researcher","foaf:name":[{"@value":"Michel Dietrich"}],"jpcoar:affiliationName":[{"@value":"Laboratoire de Geophysique Interne et de Tectonophysique Université Joseph Fourier and CNRS  Grenoble France"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"01480227"}],"prism:publicationName":[{"@value":"Journal of Geophysical Research: Solid Earth"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"2002-07","prism:volume":"107","prism:number":"B7","prism:startingPage":"2148"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F2001JB000316"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2001JB000316"}],"createdAt":"2002-10-27","modifiedAt":"2023-10-16","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050003824816585472","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Temporal variations in magnetic signals generated by the piezomagnetic effect for dislocation sources in a uniform medium"}]},{"@id":"https://cir.nii.ac.jp/crid/1050282813281947264","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Spectral peaks in electric field at resonance frequencies for seismically excited motion of ions in the Earth's magnetic field"}]},{"@id":"https://cir.nii.ac.jp/crid/1050564285764177152","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Estimation of temporal variations in the magnetic field arising from the motional induction that accompanies seismic waves at a large distance from the epicentre"}]},{"@id":"https://cir.nii.ac.jp/crid/1360285709566360192","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Circularly polarized electric fields associated with seismic waves generated by blasting"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567183238432384","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A model for observed circular polarized electric fields coincident with the passage of large seismic waves"}]},{"@id":"https://cir.nii.ac.jp/crid/1390006750774403456","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Electromagnetic Variations Associated with Seismic Waves"},{"@language":"ja","@value":"地震波に伴う電磁場変動"},{"@language":"ja-Kana","@value":"ジシンハ ニ トモナウ デンジバ ヘンドウ"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892094267776","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Numerical simulations to explain the coseismic electromagnetic signals : a case study for a M5.4 aftershock of the 2016 Kumamoto earthquake"}]},{"@id":"https://cir.nii.ac.jp/crid/2051151842057870080","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Semi-analytical solutions of seismo-electromagnetic signals arising from the motional induction in 3-D multi-layered media : part II—numerical investigations"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/2001jb000316"},{"@type":"CROSSREF","@value":"10.1111/j.1365-246x.2012.05586.x_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.1093/gji/ggt110_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.5047/eps.2011.03.010_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.4294/zisin.2020-12_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.1029/2008jb006117_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.1186/s40623-019-1122-7_references_DOI_GfUhrOuUXAxZriK73ssqoKjUorb"},{"@type":"CROSSREF","@value":"10.1093/gji/ggw125_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"},{"@type":"CROSSREF","@value":"10.1186/s40623-021-01458-5_references_DOI_W0ryGfniopIMIT15UlXDaT2RPab"}]}
