IS THIS TRUE OF URS???. Consequently the open ocean boundary of the ANUGA simulation was chosen to roughly follow the ...m depth contour along the Coast of Thailand. The North-South extent of the computational domain was chosen to maximise the number of locations for which run-up depths were measured, whilst keeping the computational domain `small enough' to avoid excessively large computational time. The computational domain is shown in Figure \ref{fig:computational_domain} 106 The utility of the URSGA model decreases with water depth unless an intricate sequence of nested grids is employed. On the other hand, while the ANUGA model is less suitable for earth quake source modelling and large study areas, it is designed with detailed on-shore inundation in mind. 107 Consequently, the Geoscience Australia tsunami modelling methodology is based on a hybrid approach using models like URSGA (or the MOST model) for tsunami generation and propagation up to a 100m depth contour where the wave is picked up by ANUGA and propagated on shore using the finite-volume method on unstructured triangular meshes. 108 109 In this case the open ocean boundary of the ANUGA study area was chosen to roughly follow the 100m depth contour along the west coast of Phuket Island. 110 The other boundaries were chosen to maximise the number of locations for which run-up depths were measured, whilst keeping the computational domain `small enough' to avoid excessively large computational time.

The authors would like to thank Diana Greenslade and the Bureau of Meteorology for conducting numerical simulations with the MOST model used to estimate the initial tsunami source. David Burbidge is also acknowledged for his help in formatting the MOST data sets. Finally we would like to thank Vasily Titov and the National Oceanic and Atmospheric Administration (NOAA) for providing bathymetry and topographic data sets.200 This project was undertaken at Geoscience Australia and the Department of Mathematics, The Australian National University.
