Geoscience Australia is the Australian Government advisor on the geology and geography of Australia, and develops the National Seismic Hazard Assessment (NSHA). The NSHA defines the level of earthquake ground shaking across Australia that has a likelihood of being exceeded in a given time period. Knowing how the ground-shaking hazard varies across Australia allows high hazard areas to be identified for the development of mitigation strategies so communities can be more resilient to earthquake events. The NSHA provides key information to the Australian Government Building Codes Board, so buildings and infrastructure design standards can be updated to ensure they can withstand earthquake events in Australia. Using the NSHA, decision makers can better consider: • What this could mean for communities in those areas and whether any further action is required • Where to prioritise further efforts • What this could mean for insurance and reinsurance premiums • Identify high and low hazard areas to plan for growth or investment in infrastructure
