The results of an investigation of the probability of earthquake damage to nonstructural unreinforced masonry (URM) components are presented. The components include parapets, chimneys, and out-of-plane loaded facades typical of low-rise pre-1940 construction in Australia and New Zealand. The study is based on a street survey of component geometry, in situ data on material strength, and simplified mechanical models. Uncertainties in capacity and demand were quantified based on, respectively, stochastic and deterministic approaches. The damage probabilities were compared with relevant guidelines and empirical damage data from three earthquakes. The study established a link between the qualitative damage states reported in existing guidelines and the quantitative URM component damage states. While some median damage state thresholds correlated well with the data from the guidelines, a larger dispersion value was found in the current study due to the large variations in component properties. Comparisons with empirical data suggest that the developed fragility data provide a realistic estimate of nonstructural component damage that occurred in similar buildings, with a reasonable level of conservatism. The outcome is useful in rapid assessment of the seismic risks due to nonstructural component collapse in URM precincts.

Extreme weather events can cause a wide range of impacts on different regions throughout Australia, including costs associated with damage to natural and built environments. Effective disaster risk reduction, emergency response, infrastructure design/operation, planning and policy making all require data and information about how extreme events will change in the future.

New data products and information are currently being developed on bushfires, tropical cyclones, east coast lows and thunderstorms (including associated hazards such as extreme rainfall, winds, hail and lightning) by a project on extreme weather events in the National Environmental Science Programme \ (NESP: \ http://nespclimate.com.au/extreme-weather-projections/). \ This \ project addresses knowledge gaps on the past and future frequency and intensity of these phenomena, including the physical processes that influence the long-term variations in their characteristics, to \ produce \ practical \ tools \ and \ guidance \ products \ for \ use \ by \ planners \ and \ decision \ makers throughout Australia.
