Results for models with constant viscosity (Model CV). a–d Results for a model case with hSP1 = 50 km, ηSP1 = 1024 Pa s and a fixed overriding plate (Fixed5024). e–h Results for a model case with hSP1 = 30 km, ηSP1 = 1023 Pa s and a free overriding plate (Free3023). a, e Change in velocities of the subducting plate (Vsp), the overriding plate (Vop), and the trench (Vtr). b–d, f–h The time evolution of the slab geometry. The distribution of effective viscosity (ηeff) is shown by corresponding colors and arrows indicate the velocity field. i Distribution of horizontal stress (σxx) in the uppermost 100 km of the model
