Selection and ranking of ground-motion models for the 2018 National Seismic...
One of the key challenges in assessing earthquake hazard in Australia is understanding the attenuation of ground-motion through the stable continental crust. There are now a... -
2018 National Seismic Hazard Assessment: Questions and Answers
The National Seismic Hazard Assessment (NSHA) is a flagship Geoscience Australia product, used to support the decisions of the Australian Building Codes Board Standards... -
National Seismic Hazard Assessment: Fact Sheet
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... -
Surface rupture and distributed deformation revealed by optical satellite...
High‐resolution optical satellite imagery is used to quantify vertical surface deformation associated with the intraplate 20 May 2016 Mw 6.0 Petermann Ranges earthquake,... -
Large earthquake recurrence on the Willunga Fault, South Australia
In mid-2022 two paleoseismic trenches were excavated across the Willunga Fault at Sellicks Hill, ~40 km south of Adelaide, at a location where range front faulting displaces a... -
Earthquake forecasting from paleoseismic records
Forecasting large earthquakes along active faults is of critical importance for seismic hazard assessment. Statistical models of recurrence intervals based on compilations of... -
Neotectonic constraint on models of strain localisation within Australian...
The mechanisms that lead to the localisation of stable continental region (SCR) seismicity, and strain more generally, remain poorly understood. Recent work has emphasised... -

The 2018 National Seismic Hazard Assessment for Australia – Data package,...
Geoscience Australia, together with contributors from the wider Australian seismology community, has produced a National Seismic Hazard Assessment (NSHA18) that is intended as... -
Periodicity and Clustering in the Long-term Earthquake Record
Instrumentally observed earthquakes sequences typically show clusters of earthquakes interspersed with periods of quiescence. These ‘bursty’ sequences also have correlated... -
Potential geologic sources of seismic hazard in Australia’s south-eastern...
Many mapped faults in the south-eastern highlands of New South Wales and Victoria are associated with apparently youthful topographic ranges, suggesting that active faulting may... -
