| 1 | The Tasmania State Emergency Service provides a |
|---|
| 2 | volunteer response capability for severe storms and floods, |
|---|
| 3 | road crash rescue, search and rescue/recovery and a range of other |
|---|
| 4 | general rescue and community support roles. |
|---|
| 5 | In addition the SES provides whole of government |
|---|
| 6 | advice and executive support to the State Disaster Committee |
|---|
| 7 | and Region Disaster Planning Groups. |
|---|
| 8 | It also takes the lead with much of the State's emergency |
|---|
| 9 | management planning and emergency risk management |
|---|
| 10 | work\footnote{http://www.ses.tas.gov.au}. |
|---|
| 11 | Such work involves understanding the relative risk |
|---|
| 12 | of a range of natural disasters so that resources can be directed to appropriate areas |
|---|
| 13 | and corresponding evacuation plans put in place. |
|---|
| 14 | |
|---|
| 15 | The key role of the Risk Research Group at Geoscience Australian |
|---|
| 16 | is to develop knowledge on the risk from natural and |
|---|
| 17 | human-caused hazards for input to policy and operational decision making on |
|---|
| 18 | the mitigation of risk to Australian communities. The Group achieves |
|---|
| 19 | this through the development of computational methods, models and decision |
|---|
| 20 | support tools that assess the hazard, vulnerability and risk posed by hazard |
|---|
| 21 | events. To develop an understanding of the tsunami risk, GA has developed |
|---|
| 22 | decision support tools, consisting of inundation |
|---|
| 23 | maps overlaid on aerial photography of the region |
|---|
| 24 | detailing critical infrastructure as well as damage modelling estimates. |
|---|
| 25 | |
|---|
| 26 | This report supports the Tasmania State Government's Natural Disaster |
|---|
| 27 | Mitigation Programme project on understanding tsunami risk to Tasmania. |
|---|
| 28 | In particular, |
|---|
| 29 | the work presented will support paloetsunami investigations to understand |
|---|
| 30 | the history of tsunami impact to Tasmania. This support provides a tsunami |
|---|
| 31 | inundation model based on a plausible event occurring on the Puysegur Trench |
|---|
| 32 | (see Section \ref{sec:methodology}). |
|---|
| 33 | |
|---|
| 34 | The modelling technique to simulate the |
|---|
| 35 | impact ashore is discussed in Section \ref{sec:methodology} and data inputs |
|---|
| 36 | discussed in Section \ref{sec:data}. |
|---|
| 37 | The inundation results are presented and discussed in Section \ref{sec:results}. |
|---|
| 38 | A summary of the results detailing issues |
|---|
| 39 | regarding underlying data and further model development, are discussed |
|---|
| 40 | in Section \ref{sec:summary}. |
