    1 The tsunamigenic event used for this study is one used
    2 to develop the preliminary tsunami hazard assessment which
    3 was delivered to FESA in September 2005,
    4 \cite{BC:FESA}. In that assessment, a suite of
    5 tsunami were evenly spaced along the Sunda Arc subduction zone and there
     1The tsunamigenic event used for this study was developed for a
     2preliminary tsunami hazard assessment study delivered to FESA in September 2005,
     3\cite{BC:FESA}. In that assessment, a suite of Mw 9 earthquakes
     4were evenly spaced along the Sunda Arc subduction zone and there
    65was no consideration of likelihood. Other sources were not considered, such
    76as intra-plate earthquakes near the WA coast, volcanoes, landslides

    1312models to develop a more complete tsunami hazard assessment
    14 for the Sunda Arc subduction zone. (This is

    17 to occur with a greater frequency, they are likely to pose a comparatively
    18 low and localised hazard to WA.

    25 shows the maximum wave height up to the 50m contour for a Mw 9 event off
    26 the coast of Java. It is this event which provides the source to the
    27 inundation modelling presented in the following section.
