Geoscience Australia builds the scientific capacity for a range of natural hazard risk and impact analyses which emergency managers and decision makers can utilise for planning and preparation through to response and recovery.

Examples of our capabilities are highlighted through a range of case studies.

Models aid in Tsunami Planning and Preparation
  • Geoscience Australia used computational modelling and Geographic Information System (GIS) mapping to assist Department of Fire and Emergency Services (WA) External site link to understand and predict the possible occurrence and propagation of tsunami in northern WA.

What would happen if Cyclone Tracy hit Darwin in 2008?
  • Through modelling and post-disaster surveys for Tropical Cyclone Tracy, Geoscience Australia was able to compare the impact in 1974 to what it would be in 2008. This study demonstrates the importance of building regulations for withstanding natural hazards.

Understanding earthquakes in Australia
  • New ground-motion prediction equations integrated with the first site-response model for Australia can refine our estimates of earthquake ground-shaking to aid earthquake disaster planning.

Modelling the impact of Tropical Cyclone Larry - Infrastructure Damage
  • Extensive modelling and field surveys were conducted in the wake of Tropical Cyclone Larry. These studies were used to show the value of comprehensive building regulations and also to estimate the possible economic impact that the cyclone inflicted.

Another earthquake in the Cadell Fault Scarp
  • Applying field assessments and conceptual models to the Cadell Fault Scarp to demonstrate the impact that an earthquake in that region would have.

Extending Australia's earthquake record beyond the instrumental era
  • High-resolution digital elevation models have been used to analyse fault scarps in Western Australia (WA). It has been discovered that South and central west WA experienced major earthquakes in prehistoric times.

Geoscience Australia contributes to Philippines landslide response
  • Geoscience Australia contributed to the Philippines landslide External site link response by being part of an AusAID External site link Landslide Assessment Team. The assessment team assisted the Philippines authorities in assessing slope stability in the area and made recommendations for future Australian assistance.

Natural Hazards in Australia: Identifying Risk Analysis Requirements Report
  • Geoscience Australia coordinated the development of a report which provides an overview of the rapid onset natural hazards which impact on Australian communities. The report emphasises data and information requirements in order to perform risk analysis for these hazards.
