Reducing the Loss": using high-resolution vulnerability assessments to enhance tsunami risk reduction strategies

Australia is at risk from tsunamis and recent work has identified the need for detailed models to assess the vulnerability of buildings to damage during tsunamis. Such models will be useful for underpinning the development of land-use zoning regulations, the identification of appropriate design standards and construction codes and in outlining community relevant tsunami disaster risk reduction strategies by local emergency managers. Such strategies might include the identification of coastal areas that require evacuation, the identification of specific buildings that might be the focus of search and rescue efforts, and the demarcation of safe evacuation areas and structures within expected tsunami flood zones. DallOsso and Dominey-Howes use the results of a very high-resolution assessment of building vulnerability to tsunami (using the PTVA -3 Model) at Manly, Sydney to illustrate how vulnerability assessments could be used to enhance tsunami risk reduction
