The 2004 Indian Ocean tsunami was caused by a large-scale fault rupture (> 1000 km) at the Indian–Australian and Eurasian–Andaman plate boundaries. This example uses the fault model of Grilli et al.  as initial conditions to a Saint-Venant solution of the subsequent tsunami. The evolution of the wave elevation is illustrated in the animation of Figure 44.a. Adaptivity is used to track the various wave fronts (Figure and animation 44.b) and the terrain is reconstructed dynamically based on the ETOPO1 dataset.
The maximum wave elevation reached over 10 hours after fault rupture is illustrated on Figure 45.
Finally Figure 46 gives a comparison of the observed (using tide gauges) and modelled timeseries at specific locations in the Indian Ocean. Figure 47 gives a comparison of the modelled wave profile with the profile observed by the Jason-1 satellite altimeter.
