Figure S8. Results of tsunami simulations for the 29 March 2015 PNG tsunami using the
sources with rupture velocities of 1.0 km/s (a), 1.25 km/s (b), 1.5 km/s (c), 1.75 km/s (d), 2.0
km/s (e), 2.25 km/s (f), 2.5 km/s (g), and 2.75 km/s (h) and comparisons with observed
waveforms. RMSE represents root-mean-square-error between simulated and observed tsunami
waveforms.
