Referring to the onshore data 32 32 discussed 33 in Section \ref{sec:data}, we choose a cell area 500 m$^2$ per triangle33 in Section \ref{sec:data}, we choose a cell area of 500 m$^2$ per triangle 34 34 for the region surrounding the Onslow town centre. 35 35 It is worth noting here that the cell … … 49 49 50km. For this scenario, the wavelength of the tsunami wave is 50 50 approximately 20km near the boundary indicating that a minimum 51 grid resolution of 20000m .51 grid resolution of 20000m would be required. 52 52 With this information, the remaining cell areas are 53 53 2500 m$^2$ for the region surrounding the coast, … … 55 55 the remainder of the study area having a cell area of 100000 m$^2$. 56 56 These choice of cell areas is more than adequate to propagate the tsunami wave 57 in the deepest sections of the study area \footnote{57 in the deepest sections of the study area.\footnote{ 58 58 With a wavelength of 20km, the minimum (square) grid resolution would 59 59 be 2000m which results in a square cell area of 4000000 m$^2$. A minimum … … 78 78 \end{figure} 79 79 80 To complete the model setup, we describe the form ofthe80 To complete the model setup, we illustrate the 81 81 tsunami wave from the earthquake source described 82 in Section \ref{sec:tsunamiscenario}. The Method of Splitting Tsunami (MOST) 83 was used to initiate the event and propagate the wave in deep water. The 84 waves amplitude and velocity is then determined at the 85 boundary of the study area (see Figure \ref{fig:onslow_area}) whereupon 86 ANUGA continues to propagate the tsunami wave in shallow water and onshore. 82 in Section \ref{sec:tsunamiscenario} which is used as the boundary condition, 83 as described in Section \ref{sec:methodology}. 84 MOST was used to initiate the event and propagate the wave in deep water. 85 ANUGA uses MOST's output in form of the waves amplitude and velocity at 86 the boundary (the 100m contour line as shown in Figure \ref{fig:onslow_area}) 87 and continues to propagate the wave in shallow water and onshore. 87 88 To illustrate the form of the tsunami wave, we select a number 88 of point locations outside, on and withinthe boundary (shown in89 Figure \ref{fig:boundarypoints}) and show the moving90 wave amplitudeand speed.89 of point locations surrouding the boundary (shown in 90 Figure \ref{fig:boundarypoints}) and show the waves movement in terms 91 of water level and speed. 91 92 92 93 \input{MOST_input_onslow} -

The damage to the residential 37 37 structures in the Onslow community 38 is summarised in Table \ref{table:damageoutput}. 38 is summarised in Table \ref{table:damageoutput}. The percentage 39 of repair cost to structural value shown is based on the total structural value 40 of \$60,187,955. Likewise, the percentage of contents loss shown is 41 based on the total contents value of \$85,410,060 for 42 the Onslow region. The injuries sustained in each scenario is summarised 43 in Table \ref{talbe:injuries}.
