From seismologically determined models of lithospheric structure, experimentally derived constitutive laws of various rocks, and densely measured geothermal gradient data, we have predicted the steady state effective viscosity across the subduction zone. The profile reveals strong lateral viscosity gradients both parallel and normal to the trench axis. The detailed viscosity structures presented here contribute to accurate evaluation of viscoelastic relaxation components when modeling geodetically measured postseismic deformation at high spatial and temporal resolution. Key Points Two-dimensional realistic viscosity profiles of the NE Japan were proposed Profiles include thermal and structural heterogeneities of the NE Japan Evaluation of viscous relaxation component requires realistic viscosity structure ©2013.
