| Zusammenfassung |
| Australia is vulnerable to the impacts of tsunamis and exposure along the SE
coast of New South Wales is especially high. Significantly, this is the same
area reported to have been affected by repeated large magnitude tsunamis
during the Holocene. Efforts are under way to complete probabilistic risk
assessments for the region but local government planners and emergency risk
managers need information now about building vulnerability in order to
develop appropriate risk management strategies. We use the newly revised
PTVA-3 Model (Dall'Osso et al., 2009) to assess the relative vulnerability
of buildings to damage from a "worst case tsunami" defined by our latest
understanding of regional risk – something never before undertaken in
Australia. We present selected results from an investigation of building
vulnerability within the local government area of Manly – an iconic coastal
area of Sydney. We show that a significant proportion of buildings (in
particular, residential structures) are classified as having "High" and
"Very High" Relative Vulnerability Index scores. Furthermore, other
important buildings (e.g., schools, nursing homes and transport structures)
are also vulnerable to damage. Our results have serious implications for
immediate emergency risk management, longer-term land-use zoning and
development, and building design and construction standards. Based on the
work undertaken here, we recommend further detailed assessment of the
vulnerability of coastal buildings in at risk areas, development of
appropriate risk management strategies and a detailed program of community
engagement to increase overall resilience. |
