Fig. 3

Examples of postseismic time series in the numerical experiments. Blue squares and red circles indicate the synthetic data in Exps. 1 and 2. Green, blue, and red lines are the theoretical time series calculated by using the first-guess and optimum frictional parameters in Exp. 1 and 2, respectively. The locations of the GNSS stations are shown in Fig. 1
