N2 - By two-dimensional finite element modeling, we modeled the observed 9-months postseismic deformation of the 2011 Tohoku-Oki earthquake. Our preferred model taking into account of inland rheological heterogeneities was able to reproduce small-scale (<20 km) deformation around a Quaternary volcano observed by the dense geodetic network. The comparison of especially dense geodetic data with models with heterogeneous rheological structures can shed light into the fine-scale thermo-rheological properties of the inland area of the NE Japan (e.g., active volcanoes).
