Ballarat Colac Infill (P199634), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Ballarat Colac Infill (P199634) contains a total of 905 point data values acquired at a spacing between 1000 and 2000 metres. The data is located in VIC and were acquired in 1996, under project No. 199634 for None.

Co-seismic surface deformation relating to the March 23, 2012 MW 5.4 Ernabella (Pukatja) earthquake, central Australia: implications for cratonic fault scaling relations in cratonic settings

On 23 March 2012, at 09:25 UTC, an Mw 5.4 earthquake occurred in the eastern Musgrave Ranges of north-central South Australia, near the community of Ernabella (Pukatja). Several small communities in this remote part of central Australia reported the tremor, but there were no reports of injury or significant damage. This was the largest earthquake recorded on mainland Australia in the past 15 years and resulted in the formation of a 1.6 km long surface deformation zone that included reverse-fault scarps with a maximum vertical displacement of more than 0.5 m, extensive ground cracking, and numerous rock falls. The earthquake occurred in non-extended stable continental region (SCR) cratonic crust, more than 1900 km from the nearest plate boundary. Surface deformation from the Ernabella earthquake provides additional constraint on relations of surface-rupture length to earthquake magnitude. Such relations aid in interpreting Australia’s rich record of prehistoric seismicity and contribute to improved estimates of SCR seismic hazard worldwide. Based upon an analysis of new and reinterpretation of existing surface-rupture length data, faults in non-extended stable cratonic Australia appear to produce longer surface ruptures (for earthquakes larger than Mw ∼ 6:5) than rupture lengths estimated using existing moment-to rupture length scaling relations. The implication is that the estimated maximum, or characteristic, magnitude of paleoearthquakes in such settings may be overestimated where the estimate is based only on the length of the prehistoric fault scarp.

Carnarvon Basin hydrogeological inventory

This Carnarvon Basin 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.
The Carnarvon Basin is a large sedimentary basin covering the western and north-western coast of Western Australia, stretching over 1,000 km from Geraldton to Karratha. It is predominantly offshore, with over 80% of the basin located in water depths of up to 4,500 m. The basin is elongated north to south and connects to the Perth Basin in the south and the offshore Canning Basin in the north-east. It is underlain by Precambrian crystalline basement rocks.
The Carnarvon Basin consists of two distinct parts. The southern portion comprises onshore sub-basins with mainly Paleozoic sedimentary rocks extending up to 300 km inland, while the northern section consists of offshore sub-basins containing Mesozoic, Cenozoic, and Paleozoic sequences.
The geological evolution of the Southern Carnarvon Basin was shaped by multiple extensional episodes related to the breakup of Gondwana and reactivation of Archean and Proterozoic structures. The collision between Australia and Eurasia in the Mid-Miocene caused significant fault reactivation and inversion. The onshore region experienced arid conditions, leading to the formation of calcrete, followed by alluvial and eolian deposition and continued calcareous deposition offshore.
The Northern Carnarvon Basin contains up to 15,000 m of sedimentary infill, primarily composed of siliciclastic deltaic to marine sediments from the Triassic to Early Cretaceous and shelf carbonates from the Mid-Cretaceous to Cenozoic. The basin is a significant hydrocarbon province, with most of the resources found within Upper Triassic, Jurassic, and Lower Cretaceous sandstone reservoirs. The basin's development occurred during four successive periods of extension and thermal subsidence, resulting in the formation of various sub-basins and structural highs.
Overall, the Carnarvon Basin is a geologically complex region with a rich sedimentary history and significant hydrocarbon resources. Exploration drilling has been ongoing since 1953, with numerous wells drilled to unlock its hydrocarbon potential.

GSNSW Exploration NSW Area K Peel magnetic first vd grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 GSNSW Exploration NSW Area K Peel magnetic first vd grid geodetic is a first vertical derivative of the Total Magnetic Intensity grid for the NSW DMR, Discovery 2000 Area K, Peel (Inverell,Manilla), NSW, 1998.
This grid has a cell size of 0.00048 degrees (approximately 50m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 1998 by the NSW Government, and consisted of 61165 line-kilometres of data at 250m line spacing and 60m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Tallaringa South - dose rate grid (AWAGS)

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. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid.
This Tallaringa South - dose rate grid (AWAGS) has a cell size of 0.0004 degrees (approximately 42m) and shows the total dose rate of the Tallaringa South Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 146285 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Does PSHA Meet the Needs for Modern Engineering Design In Australia?

Damaging earthquakes in Australia and other regions characterised by low seismicity are considered low probability, high consequence events. Uncertainties in modeling earthquake occurrence rates and ground motions pose unique challenges to forecasting seismic hazard in these regions. In 2018 Geoscience Australia released its National Seismic Hazard Assessment (NSHA18). Results from the NSHA18 indicate significantly lower seismic hazard across almost all Australian localities at the 1/500 annual exceedance probability (AEP) relative to the factors in the Australian earthquake loading standard; the AS1170.4. Due to concerns that the 1/500 AEP hazard factors proposed in the NSHA18 would not assure life safety throughout the continent, the amended AS1170.4 (revised in 2018) retains seismic demands developed in the early 1990s and also introduces a minimum hazard design factor of Z = 0.08 g. The hazard estimates from the NSHA18 have challenged notions of seismic hazard in Australia in terms of the probability of damaging ground motions and raises questions as to whether current practices in probabilistic seismic hazard analysis (PSHA) deliver the outcomes required to protect communities in low-seismicity regions, such as Australia. By contrast, it is also important that the right questions are being asked of hazard modelers in terms of the provision of seismic demand objectives that are fit for purpose. In the United States and Canada, a 1/2475 AEP is used for national hazard maps due to concerns that communities in low-to-moderate seismicity regions are considerably more at risk to extreme ground-motions. The adoption of a 1/2475 AEP seismic demands within the AS1170.4 would bring it in to line with other international building codes in similar tectonic environments and would increase seismic demand factors to levels similar to the 1991 hazard map. This, together with other updates, may be considered for future revisions to the standard.
