Seismic hazard estimation in stable continental regions: Challenges and opportunities

Damaging earthquakes in Australia and other regions characterised by low seismicity are considered low probability but high consequence events. Uncertainties in modelling earthquake occurrence rates and ground motions for damaging earthquakes in these regions imposes unique challenges on forecasting seismic hazard and the use of this information for improving seismic safety within our communities.  Key challenges for these regions are explored, including: the quality and continuity of earthquake catalogues; the difficulties in characterising earthquake ground motions; the uncertainties in earthquake source modelling, and; the consideration of modern earthquake hazard information to support future building provisions.

GSSA Torrens percent Potassium grid geodetic

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 radiometric potassium grid has a cell size of 0.0004 degrees (approximately 41m) and shows potassium element concentration of the Torrens Airborne Magnetic Radiometric and DEM Survey, SA, 2017 in units of percent (or %). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 83653 line-kilometres of data at 200m line spacing and 60m terrain clearance.

A national-scale vulnerability assessment of seawater intrusion: Vulnerability Factor Analysis

Fresh groundwater stored in Australian coastal aquifers constitutes an important resource for humans and the natural environment. However, many Australian coastal aquifers are vulnerable to seawater intrusion (SWI) - the landward encroachment of seawater into coastal aquifers. SWI can significantly degrade water quality and reduce freshwater availability.
In response to the threat posed by SWI, Geoscience Australia (GA) and the National Centre for Groundwater Research and Training (NCGRT), in collaboration with state and territory water agencies, have undertaken a national scale assessment of the vulnerability of coastal aquifers to SWI.  This assessment aims to identify the coastal groundwater resources that are most vulnerable to SWI and considers the future consequences of over-extraction, sea-level rise, and recharge-discharge variations associated with climate change. 
In order to achieve the project aims, the study comprised five technical assessments to analyse factors contributing to the vulnerability of coastal aquifers: (i) vulnerability factor analysis (VFA); (ii) coastal aquifer typology; (iii) mathematical analysis; (iv) SWI quantitative and qualitative vulnerability indexing; and, (v) future land surface inundation and population growth analysis. 
This report covers the VFA component of the project which provides a first-pass, regional assessment of SWI vulnerability indicators in Australia's coastal areas based on state and territory groundwater datasets for individual groundwater bores. A large number of measurements were collated for this project.  In total, more than 1.7 million groundwater levels and more than 1.1 million salinity measurements were compiled and evaluated.

Yilgarn Craton GeoPDF

The Yilgarn online GIS displays a wide range of data including geological datasets, topographical data, geophysical images and seismic traverses, whole rock geochemistry and geochronology samples. It provides an  aeromagnetic interpretation (lithology distribution and structure)  and a geological interpretation of the Archaean Yilgarn Craton, one of Australia's key mineral provinces. The online GIS also focuses on the Leonora-Neale Transect, by providing a detailed solid geology interpretation of the section. The Yilgarn Craton occurs within Western Australia and covers 10% of the Australian continent. Exposure of bedrock is extremely poor throughout the region and most known mineral deposits occur within or adjacent to sparse outcrop. The online GIS provides a view through the poorly magnetised cover to display bedrock distribution. Interpreted rock types of the region include granite, granitic gneiss, layered intrusions and sills. Interpreted structural elements include lithological banding, faults, and dyke swarms. Also presented are several surrounding and partially overlying Proterozoic and Phanerozoic basins and provinces.
The Yilgarn Craton is arguably Australia's premier mineral province, attracting more than half the mineral exploration expenditure, and producing two thirds of the gold and most of the nickel mined in the country. For this reason, the online GIS provides the ability to display all deposits in the region or the option of displaying gold or nickel deposits only. Distribution of mineral deposits can be compared to other data layers including geology, and aeromagnetic domains.
This map has been produced as a GeoPDF, which is an extension to the standard PDF file format viewed using Adobe Acrobat Reader. Layers can be turned off and on to customise the view of the data, similar to using Geographic Information System tools. In addition, GeoPDF maps are georeferenced to be compatible with other coordinated geographic data. Coordinate locations and distances can be retrieved automatically.
A plug-in to view GeoPDF using Adobe Acrobat Reader is available as a free download ( http://terragotech.com/solutions/map2pdf_reader.php ).

National-scale vulnerability assessment of seawater intrusion: summary report

Fresh groundwater stored in Australian coastal aquifers is an important resource for humans and the natural environment. Many Australian coastal aquifers are vulnerable to seawater intrusion (SWI)—the landward encroachment of sea water into coastal aquifers—which can significantly degrade water quality and reduce freshwater availability. The increasing demands for fresh water in coastal areas and the anticipated impacts of climate change (such as sea-level rise and variations in rainfall recharge) may result in increases in the incidence and severity of SWI. Comprehensive investigations of SWI are relatively uncommon and the extent of monitoring and investigations specific to SWI are highly variable across the nation.
In response to the threat posed by SWI, Geoscience Australia and the National Centre for Groundwater Research and Training, in collaboration with state and territory water agencies, undertook a national-scale assessment of the vulnerability of coastal aquifers to SWI. This assessment identified the coastal groundwater resources that are most vulnerable to SWI, including future consequences of over-extraction, sea-level rise, and recharge–discharge variations associated with climate change. The study focused on assessing the vulnerability of coastal aquifers to the landward migration of the freshwater–saltwater interface, rather than surface waterbodies.

L067 Bullsbrook seismic survey, Perth Basin, WA, 1964

Seismic reflection studies in the Perth Basin, between the coast and the Darling Range, 30 miles north of Perth, were conducted in an attempt to derive a suitable recording technique for obtaining reflections when shooting on the Coastal Limestone formation, to investigate geological structure in the basin,and to supplement hydrological studies being madeby the Geological Survey of Western Australia. Experimental work occupying half of the survey period failed to yield a technique for obtaining seismic reflections on the Coastal Limestone, but led to reflections being obtained across the major part of the basin, Record quality with a fairly heavy technique was poor to fair in the western half of the basin off the Coastal Limestone but improved considerably to the east. A complex geological section in the west gave way to a more concordant thick synclinal section in the east, terminated at its eastern end by the Darling Fault. Of interest is an apparent anticlinal reversal of dip in beds lying deeper than 7000 ft,with the reversal axis near the centre of the major gravity 'low' of the basin.
