r7249 r7253 81 81 to solve the governing equations. However any legitimate model must 82 82 address each of the three distinct stages of tsunami evolution--- 83 generation, propagation and inundation. Geological models must be used 83 generation, propagation and inundation. Models combining observed seismic, 84 geodetic and sometimes tsunami data must be used 84 85 to provide estimates of initial sea floor and ocean surface 85 86 deformation. The complexity of these models range from empirical to … … 171 172 benchmark to validate an operational tsunami inundation model called 172 173 \textsc{anuga} used by Geoscience Australia. A description of 173 \textsc{anuga} is given in Sec ion~\ref{sec:models} and the validation174 results are given in Sec ion~\ref{sec:results}.174 \textsc{anuga} is given in Section~\ref{sec:models} and the validation 175 results are given in Section~\ref{sec:results}. 175 176 176 177 The numerical models used to model tsunami are extremely … … 208 209 by the 2004 Sumatra--Andaman earthquake. 209 210 210 The 2004 Sumatra--Andaman tsunami was generated by severe coseismic211 The 2004 Sumatra--Andaman tsunami was generated by a severe coseismic 211 212 displacement of the sea floor as a result of one of the largest 212 213 earthquakes on record.

The second video is in the very south 419 420 filmed from the second story of a building next door to the Comfort 420 421 Resort near the corner of Ruam Chai St and Thaweewong Road. This 421 location is marked 'south' in Figure \ref{fig:gauge_locations} and422 location is marked ``south'' in Figure \ref{fig:gauge_locations} and 422 423 Figure~\ref{fig:video_flow} shows stills from this video.

The interface between the \textsc{ursga} 724 726 and \textsc{anuga} models was chosen to roughly follow the 100 m depth 725 727 contour along the west coast of Phuket Island.
