Geoscience Australia develops computational models to underpin natural hazard risk and impact analysis. The models described here can be utilised for hydrodynamic simulations, earthquake simulations and tropical cyclone simulations. These models are open source and can be downloaded for public use.

In order to simulate the behaviour of water flow from natural hazards such as riverine flooding, storm surges or tsunami within the built environment, Geoscience Australia and the Australian National University have developed a software modelling tool called ANUGA for hydrodynamic simulations.

Strong ground-shaking from earthquakes can result in severe damage to the built environment. To model impacts on communities from earthquakes, Geoscience Australia have developed the Earthquake Risk Model (EQRM) which can simulate the estimated ground-shaking from an earthquake of a given magnitude and location, and subsequently calculate the impact to a portfolio of buildings.

To simulate cyclonic wind activity over many thousands of years or examine the impact of a single tropical cyclonic event on a community, Geoscience Australia have developed the Tropical Cyclone Risk Model (TCRM).
