Schematic diagram of deformation sources beneath the seafloor. a Slips on the plate interface. Purple, red, and orange regions indicate possible afterslip region and geodetically derived (Iinuma et al. 2012) and tsunami-derived (Satake et al. 2013) coseismic slip areas of the 2011 Tohoku-oki earthquake, respectively. Blue circles and bars indicate the locations of GNSS-A sites and their projections to the plate interface, respectively. Black rectangles show the locations for cross sections illustrated in subsequent panels. Note that little or no information for the spread of afterslip regions can be added by the present GNSS-A data. b Cross sections for each region with one of possible qualitative explanations for the contributions of each deformation source to the motion at GNSS-A sites. Black, red, purple, and yellow arrows indicate the observed motion and components due to viscoelastic relaxation, afterslip, and interplate coupling, respectively
