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 Subcommittee BD-006-11, to ensure buildings and infrastructure are built to withstand seismic events in Australia. 
The NSHA has been updated in 2018 and includes significant advances on previous assessments including: inclusion of epistemic uncertainty using third-party source models contributed by the Australian seismology community, use of modern ground-motion models, and more.  As a consequence of these advances, estimates of seismic hazard have decreased significantly across most Australian localities at the return period (of earthquake ground shaking) currently used by the Australian Standard.
The objective of this document is to outline the significant changes to the NSHA18 from the 2012 version, and the science behind these changes. The responses were developed through feedback and consultation with experts in the seismic and engineering industry. If you have additional questions, please contact the project team at hazards@ga.gov.au.

Triassic Horizon Grids, Isochron Grids, and Fault Maps, Central North West Shelf

A regional mapping program conducted by Geoscience Australia addressed stratigraphic and structural aspects of exploration risk within the Triassic succession of the Roebuck Basin and parts of the adjacent sub-basins (central North West Shelf, Figure 1).
Seismic horizons of regional significance were mapped using 2D and 3D seismic surveys. Seismic survey coverage is shown in Figure 1. 2D surveys include regional deep surveys such as AGSO s110, AGSO s120, and PGS New Dawn. 3D surveys include Admiral, Beagle, CNOOC, Curt, Lord, Naranco, Polly, Whitetail, and a 5 x 5 km extract (used with permission) from the TGS Capreolus MC3D. Synthetic seismograms (Nguyen et al., 2019) were used to tie seismic horizons to wells.
The mapped horizons are placed within a regional tectonostratigraphic framework by Abbott et al. (2019, their Figure 2). This data pack comprises seismic horizon grids and isochron grids generated from the TR10.0_SB (base Triassic), TR17.0_SB (Mid–Triassic), and J10.0_SB (top Triassic) seismic horizons (Figure 2). Fault maps compiled at the TR10.0 _SB and J10.0_SB are also included.

Limbunya Napier, NT, 1995 (P612), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Limbunya Napier, NT, 1995 (P612), radiometric line data, AWAGS levelled were acquired in 1995 by the NT Government, and consisted of 60157 line-kilometres of data at 500m line spacing and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

The Saunders Creek radioactive prospect, Halls Creek district, Western Australia

The radiometric anomalies recorded by Bureau of Mineral Resources airborne scintillometer surveys and by ground investigations at the Saunders Creek Radioactive Prospect (Halls Creek W.A.) are associated with the Saunders Creek Formation. This formation has been newly defined to include a succession of coarse to medium clastics which were formed in a phase of shallow water conditions during the cycle of the Halls Creek Geosyncline. The conglomerate at the base of the formation, and in particular the heavy mineral matrix which contains thorogummite, is the source of radioactivity. The conglomerate crops out for 3 miles along the western limb of a closed anticline in the area, where structure is complicated by strike faulting and isoclinal folds. Readings for radioactivity are from 3 to 10 times background. Two bore sites have been located for the testing of the formation below the zone of oxidation.

Stakeholder Workshop Report (21 April 2016)

A stakeholder workshop for NESP Project D1 ¿Ecosystem understanding to support sustainable use, management and monitoring of marine assets in the North and North-west regions¿ was held at the University of Western Australia, Perth, on 21 April 2016. The objective of the workshop was to identify stakeholder information needs in the North and North-west regions and use these to guide research activities in Project D1.
Stakeholders from State and Local Government departments, Industry, Fisheries, Conservation, and Indigenous groups each explained their priorities and issues in the North and North-west region, after which geographic focus, research scope, and data delivery needs were discussed across the group and prioritised through a post-workshop online survey.
From a stakeholder perspective, the geographic focus of research should be prioritised towards Commonwealth Marine Reserves (particularly the Kimberly and Gascoyne areas) and areas under the highest pressure. Stakeholders considered that research in Project D1 should be targeted towards using predictive models to characterise and map benthic habitats and demersal fish species. There was positive feedback from Stakeholders regarding the Northwest Atlas as a platform for the communication of research outcomes and as a repository for information relevant to management of the regions, with a number of suggestions made for making information more readily searchable within that framework.
Combined outcomes from the D1 Stakeholder Workshop and the earlier D1 Science Workshop will provide direction for future research within Project D1 and contribute to the National Prioritisation workshop with Project D3.

Gravity and magnetic enhancement grids and images for the Otway Basin Seismic Program 2020

In association with the OB2020 seismic survey, over 8,200 line kilometre of gravity and magnetic data were acquired. These data were subsequently merged with existing satellite data to produce merged grids at 1000m grid cell size. 
Several enhancement processing techniques were applied to these magnetic and gravity data to better highlight buried features within the Otway Basin. The merged input data from the survey and the enhanced products in this release provide valuable information on the geometry and spatial extent of igneous rocks in the deep-water basin. The distribution of these rocks is critical to the understanding of the petroleum systems and therefore the hydrocarbon prospectivity of the area.
This data package contains: 
1) A metadata statement document
2) Shapefiles of the magnetic and gravity line data from the OBSP survey
3) ASCII xyz grids of the OBSP and merged grids with public domain data
4) Georeferenced (GeoTIFF) images of the survey and merged grids
5) Gravity and Magnetic data processing reports from the OBSP survey

The availability of ground water at Bushy Park homestead

Groundwater at Bushy Park Homestead is contained in fractures in amphibolite, gneiss and schist under lying a thin cover of soil and alluvium. Results from drilling and constant separation resistivity traverses suggest that the weathering fractures, tapped by bores drilled to date, will not maintain adequate groundwater supplies. Further search should be for tectonic fractures which may be open to greater depth.

South-east Australian Fractured Rock Province hydrogeological inventory

This South-east Australian Fractured Rock Province dataset contains descriptive attribute information for the areas bounded by the relevant spatial groundwater feature in the associated Hydrogeology Index map. Descriptive topics are grouped into the following themes: Location and administration; Demographics; Physical geography; Surface water; Geology; Hydrogeology; Groundwater; Groundwater management and use; Environment; Land use and industry types; and Scientific stimulus.
Groundwater in Australia's fractured rock aquifers is stored in fractures, joints, bedding planes, and cavities within the rock mass, comprising about 40% of the country's groundwater. Much of this water can be utilized for irrigation, town water supplies, stock watering, and domestic use, based on state regulations. Fractured systems account for approximately 33% of all bores in Australia but contribute to only 10% of total extraction due to variable groundwater yield.
Quantifying groundwater movement in fractured rock systems is challenging, as it depends on the distribution of major fractures. Groundwater flow direction is more influenced by the orientation of fractures than hydraulic head distribution. Recharge in fractured rock aquifers is typically localized and intermediate.
In Eastern Australia, New South Wales' Lachlan Orogen, which extends from central and eastern New South Wales to Victoria and Tasmania, is a significant region with diverse lithological units, including deep marine turbidites, shallow marine to sub-areal sediments, extensive granite bodies, and volcano-intrusive complexes. This region contains various mineral deposits, such as orogenic gold, volcanic-hosted massive sulphide, sediment-hosted Cu-Au, porphyry Au-Cu, and granite-related Sn.
Note: The study does not include additional Orogens in the east (New England) and west (Thomson and Delamerian). The Delamerian Orogen is present throughout western Tasmania.
