It is intended to ensure the NSHA18 outputs are openly available, discoverable and accessible to both internal and external users. This geospatial product is derived from the dataset generated through the development of the NSHA18 and contains uniform probability hazard maps for a 10% and 2% chance of exceedance in 50 years. These maps are calculated for peak ground acceleration (PGA) and a range of response spectral periods, Sa(T), for T = 0.1, 0.2, 0.3, 0.5, 1.0, 2.0 and 4.0 s. Additionally, hazard curves for each ground-motion intensity measure as well as uniform hazard spectra at the nominated exceedance probabilities are calculated for key localities. {"type": "Polygon", "coordinates": [[[109.1357, -48.6349], [157.9857, -48.6349], [157.9857, -6.1349], [109.1357, -6.1349], [109.1357, -48.6349]]]} 109.1357 157.9857 -48.6349 -6.1349 Earth Science Earth Science | Human Dimensions | Natural Hazards | Earthquakes Geographic Information System MapServer Published_External web service National Seismic Hazard Assessment 2018 MapServer documentDigital National Seismic Hazard Assessment 2018 MapServer HTML Unnamed resource documentDigital HTML Unnamed resource documentDigital HTML
