Thin-sheet electromagnetic modeling of magnetovariational data for a regional-scale study
International audience Naturally existing electromagnetic (EM) fields recorded at the surface of the Earth can be used to infer the electrical conductivity distribution of the subsurface. In the magnetovariational sounding (MVS) technique, the transient variations of orthogonal components of the Ear...
