Forecast results and a rectangular fault model. a Estimated maximum tsunami height (red) with that of the tsunami scenario of Fig. 2 (black). b Estimated tsunami source. c Surface deformation based on a rectangular fault model assumed to be obtained from operational real-time seismic/geodetic data analysis. The forecast results are obtained using 3–20-min pseudo observation data from the PPP ship height (λ = 0.05) but excluding those at a region from 134° to 137°E (Fig. 3b). Left and right panels show the forecast result using the 55 ship data, and that using not only the 55 ship data but incorporating the fault model of c, respectively. Correlation coefficients between the estimation and the tsunami scenario of Fig. 2 are shown in the right-bottom sides in a and b
