Résumé

This paper presents the inversion of linear and equivalent linear soil profile (i.e., S-wave velocity and damping factor) at the KiK-net station MYGH10 during the Great Tohoku Earthquake, 2011. Due to possible strong 2D or 3D topographic effects at the station located close to mountainous areas, we carefully select weak motions that present few of those effects. Among 50 weak motions, only 5 are selected to check the linear profile of the site. Then, the equivalent linear soil profile during the main shock is inverted, showing very interesting nonlinear effects, such as bedrock nonlinearity.
