Abstract
In 2012 Geoscience Australia produced a National Seismic Hazard Map (NSHM) of Australia using the Probabilistic Seismic Hazard Assessment (PSHA) methodology. The primary product of the project was single 500 year return period Peak Ground Acceleration (PGA) map GA record 2012/71. For this assessment the hazard has been calculated for 14 return periods (100 - 100,000 years) and 21 SA periods (0.0 - 5.0s), giving 294 hazard layers (maps) for 48000 sites across Australia. We show five of the possible 294 hazard maps and 34 of the tens of thousands of possible hazard curves and spectra. These were selected to cover the main types of additional maps that have been requested since the NSHM was released and to cover a reasonable range of return periods, SA periods and locations. In this record, the probability factor (Kp) curve given in AS1170.4 is also compared to the curves calculated for the eight capital cities. Finally, the hazard spectra for the capital cities and some selected locations is compared to the spectra for site class Be given in AS1170.4.
