Post-seismic deformation (IMAGE) Ehime University Caption Upper: A cross-section view of a subduction zone just after an earthquake on the plate boundary. Tensile stress is coseismically induced in the plates. Lower: A few years after the earthquake. Post-seismic displacements of land are significant due to the upwelling flow of the uppermost mantle induced by the earthquake. After Sun et al. (2014 Nature).
