The corrections of the gravity data. a The raw data (g 0 ) at OMZ (blue), KKG (brown) and TYH (green) and the apparent effect caused by vertical displacements (g h ). The gray and red bars denote the periods of the SSEs. b g 1 = g 0 − g h and the effects of crustal dilatation caused by slip deficit and slow slip on the plate interface (g d ). c g 2 = g 1 − g d and the effect by the post-seismic relaxation of the 2011 Tohoku earthquake (g p ). d g 2 ′ = g 2 − g p and the estimated groundwater noises. The blue lines represent the gravity change calculated from the soil parameters determined by the inversion (g w (LSQ)). The red and gray lines, respectively, denote the average of the groundwater noises estimated for all the allowable parameters and the maximum and the minimum of them. e g 3 = g 2 ′ − g w (ave). f g3′ = g 2 ′ − g w (LSQ)
