Model of postseismic deformation by Sun et al. (2014). a Burgers rheology model. b 2D cross section of the 3D model of the 2011 Tohoku-oki earthquake constructed by Sun et al. (2014). The most seaward part of the wedge covering the slab area shallower than 70 km has an elastic “cold nose.” It also includes a weak layer (LAB) beneath the oceanic plate. c Coseismic displacement of the 2011 Tohoku-oki earthquake at the GPS sites on land (Ozawa et al. 2011) and ocean floor (Sato et al. 2011; Kido et al. 2011) shown with the displacement predicted by the fault slip model (Iinuma et al. 2012). d Postseismic displacement of the 2011 Tohoku-oki earthquake. Displacement on land (Ozawa et al. 2012) and seafloor (Japan Coast Guard and Tohoku University 2013; Watanabe et al. 2014) GPS sites during the first year after the earthquake and model predictions using the viscoelastic finite element method of Sun et al. (2014). Black contours (m) are the postseismic slip distribution used in modeling. b–d are after Sun et al. (2014)
