Additional file 1 of Azimuthal differences and changes in strain rate and stress of the Japanese Islands deduced from geophysical data

Additional file 1: Data S1. (e.g., 1997-2000.out) The estimation results of the strain rate fields for the 19 periods in Fig. 2. We set Wt = 12 for Phase 1 (1997–2000 to 2008–2011) and Phase 3 (2016–2019 to 2018–2021), and Wt = 4 for Phase 2 (2012–2015 to 2015–2018). The first column of data represents the longitude of the grid point, the second does the latitude, the third does the optimized smoothing distance D [km], the fourth does the dilatational strain rate [nstrain/year], the fifth does the maximum shear strain rate [nstrain/year], and the sixth does the azimuth of the maximum contraction of strain rate $${\tau }_{\mathrm{Hmax}}$$ τ Hmax [°].
