Large earthquake recurrence on the southern Willunga Fault, South Australia
The presence of Pliocene marine sediments in the Myponga and Meadows basins within the Mt Lofty Ranges south of Adelaide is testament to over 200 m of tectonic uplift... -
The 2018 National Seismic Hazard Assessment for Australia: Model input files
This Geoscience Australia Record contains technical data and input files that, when used with the Global Earthquake Model’s (GEM’s) OpenQuake-engine probabilistic seismic hazard... -
Yes, earthquakes happen in Australia - are we prepared?
People in Australia are surprised to learn that hundreds of earthquakes occur below our feet every year. The majority are too small to feel, let alone cause any damage. Despite... -
Expert elicitation of model parameters for the 2018 National Seismic Hazard...
The 2018 National Seismic Hazard Assessment (NSHA18) aims to provide the most up-to-date and comprehensive understanding of seismic hazard in Australia. As such, NSHA18 includes... -
Exploring Australian Hazard Map Exceedance Using an Atlas of Historical ShakeMaps
This paper explores several area-based tests of long-term seismic hazard forecasts for the Australian continent. Using the observed seismicity, ShakeMaps are calculated for... -
A record of stable continental region earthquakes from Western Australia...
In plate boundary regions moderate to large earthquakes are often sufficiently frequent that fundamental seismic parameters such as the recurrence intervals of large earthquakes... -
10% in 50 year seismic hazard map
The 10% in 50 year seismic hazard map is the key output from the 2018 National Seismic Hazard Assessment for Australia (NSHA18) as required for consideration by the Standards... -
The 2018 National Seismic Hazard Assessment for Australia
Geoscience Australia, together with contributors from the wider Australian seismology community, has produced a National Seismic Hazard Assessment (NSHA18) that is intended as... -
Site Classification and VS30 Determination for Seismic Hazard Evaluation in...
Seismic site classification is essential for seismic hazard analysis as it helps constrain the impact of local geological conditions on the near-surface seismic-wave... -

The 2018 national seismic hazard assessment of Australia: Quantifying hazard...
Seismic hazard assessments in stable continental regions such as Australia face considerable challenges compared with active tectonic regions. Long earthquake recurrence... -
Earthquake sources of the Australian plate margin: Revised models for the...
Located within an intraplate setting, continental Australia has a relatively low rate of seismicity compared with its surrounding plate boundary regions. However, the plate... -
Neotectonic Features in the Snowy Monaro Region, NSW
The Snowy Monaro region of NSW hosts infrastructure critical to Australia’s water and energy security. The region also contains several neotectonic features that show evidence... -
The 2018 National Seismic Hazard Assessment: Model overview

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...
