2 | The purpose of this section is show the maximum inundation map for each |
---|
3 | slide scenario for region A, B and C. The Bulli slide is considered to |
---|
4 | have occurred with the Shovel and Yacaaba considered as potential slides. |
---|
5 | The modelling effectively describes the output as a function of slide |
---|
6 | volume with Bulli the largest. The outputs should thus be interpretted |
---|
7 | as potential outputs with the Bulli volume occurring in region A as the |
---|
8 | only to have occurred. This event may be used in paleo-tsunami |
---|
9 | investigations due to occur in early 2007. The remaining events may |
---|
10 | then be used to described the potential tsunami inundation for slides |
---|
11 | of varied volume. |

31 | Figures \ref{fig:bulliA}, \ref{fig:bulliB} and \ref{fig:bulliC} |
---|
32 | describe the inundation extent to regions A, B and C respectively |
---|
33 | for the Bulli volume. Similarly, Figures \ref{fig:shovelA}, \ref{fig:shovelB} |
---|
34 | and \ref{fig:shovelC} describe the inundation extent for the Shovel |
---|
35 | volume with Figures \ref{fig:yacaabaA}, \ref{fig:yacaabaB} and |
---|
36 | \ref{fig:yacaabaC} describing the inundation extent for the Yacaaba volume. |
---|
37 | It is immediately apparent that there is little difference in the |
---|
38 | inundation extents between the Bulli and Shovel slide volumes. The reason |
---|
39 | for this may possibly be explained in Figure \ref{fig:depthvsamp}. Here, the |
---|
40 | characteristic three dimensional |
---|
41 | amplitude is determined as a function of depth for each |
---|
42 | slide volume (see Appendix \ref{sec:smfmodel}. |
---|
43 | The location of each specific slide is marked on its |
---|
44 | corresponding volume. |
---|
45 | As Figure \ref{fig:depthvsamp} shows, even though the Bulli and Shovel |
---|
46 | slides are considered to occur in different depths of water, the |
---|
47 | resultant amplitude are approximately equal. |
