Figure 2
Time series showing modeling results in terms of rock composition for the two tectonic scenarios (Model 14 and Model 23) investigated in this study. Convergence rate and age are shown at the bottom of each time series. The figure shows the time steps each 3 Ma, where the circles that change color from red to pink represent the convergence rate, age, and trough axis position in the time steps indicated. All simulations are performed with an initial dip angle of the weak zone of 20°. (A) Model 1 is based on Kimura et al. (2014) 4 tectonic model. (B) Model 2 is based on Tatsumi et al. (2020)3 tectonic model. The black line represents the convergence rate normal at the Nankai Trough, and the green line represents the PHS plate age changes at the trough. This figure is created using Matlab R2022 and Corel Draw 2022.
