Some examples of how we have delivered these capabilities include:

  • The Tropical Cyclone Risk Model (TCRM) was used to assess the impacts of Tropical Cyclone Tracy on Darwin in 1974 and also to model the impact if the same event occurred in 2008. The TCRM provides emergency managers with spatial information on areas likely to suffer significant damage to support operational decision-making processes. The analysis of the two scenarios highlighted the benefits of improved building standards 
  • an earthquake hazard map was developed for the Perth region indicating the chance of a given shaking-level being exceeded over a given time period at a given location. The map highlights potential hazard to emergency managers and informs earthquake building standards
  • a national shoreline geomorphic and stability map called 'Smartline' was used in combination with an exposure database 'NEXIS' (to complete a preliminary assessment of the economic risks to coastal communities). This provides fundamental information to decision-makers by identifying areas in Australia's coastal zone that may be significantly impacted by climate change
  • remote sensing and GIS were used to extract a riverine and flash flood ‘footprint’ of the 2007 Newcastle floods. This footprint was used to extract information held within 'NEXIS' about buildings and people within the affected area. The information was used to help inform funding arrangements and assist communities in recovery
  • post-disaster surveys were completed by Geoscience Australia officers to determine how vulnerable particular forms of construction, building ages and demographics were during Tropical Cyclone Larry. This information can inform building codes, validate impact modelling and also provides emergency managers with information to use in response planning.
