Time series of seafloor displacement at GNSS-A sites along the Japan Trench: from March 2011 to June 2020 and before the 2011 Tohoku-oki earthquake

DataS1.xlsx contains time series of postseismic seafloor displacements following the 2011 Tohoku-oki earthquake at GNSS-A sites along the Japan Trench with respect to the Eurasian plate of NUVEL-1A model (DeMets et al., 1994), which are derived from the GNSS-A data (Watanabe et al., 2021b) using GARPOS version 1.0.0 (Watanabe et al., 2021c). 

DataS2.xlsx contains time series of preseismic seafloor displacements before the 2011 Tohoku-oki earthquake at GNSS-A sites along the Japan Trench with respect to the Eurasian plate of NUVEL-1A model (DeMets et al., 1994), which are derived from the GNSS-A data (Watanabe et al., 2021a) using GARPOS version 1.0.0 (Watanabe et al., 2021c). 

The reference locations of GNSS-A sites are listed in DataS3.xlsx. Note that the precise positions of seafloor acoustic transponders can be available from the GNSS-A dataset (Watanabe et al., 2021a; 2021b).
