West Eucla Basin (Culver), WA, 1983 (P493), 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 West Eucla Basin (Culver), WA, 1983 (P493), radiometric line data, AWAGS levelled were acquired in 1983 by the WA Government, and consisted of 9699 line-kilometres of data at 1500m line spacing and 150m 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.

Shear Wave Velocity measurement at Australian Ground Motion Seismometer Sites by the Spectral Analysis of Surface Waves (SASW) Method

Near-surface shear-wave velocity profiles were acquired at eighteen permanent and temporary seismograph sites in Western Australia, South Australia, Victoria and New South Wales. These data were obtained to support ground-motion modelling in Australia by characterising the near-surface response at sites used to record ground-motion from Australian earthquakes. 
Geoscience Australia contracted the US Geological Survey to obtain shear-velocity data using the Spectral Analysis of Shear-Waves (SASW) technique. Velocity profiles were calculated down to maximum depths between 100-200m. Apart from two sites on alluvium, all sites were located on hard rock at or near the surface. The average velocity to 30m depth (Vs30) ranges from 257 m/s for alluvial sites to 1652 m/s for Proterozoic metasediments.

Opportunities to enhance seismic demand parameters for future editions of the AS1170.4

Geoscience Australia has recently released its 2018 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 level relative to the factors adopted for the current Australian Standard AS1170.4–2007 (R2018). These new hazard estimates, coupled with larger kp factors, have challenged notions of seismic hazard in Australia in terms of the recurrence of damaging ground motions. As a consequence, the new hazard estimates have raised questions over the appropriateness of the prescribed probability level used in the AS1170.4 to determine appropriate seismic demands for the design of ordinary-use structures. Therefore, it is suggested that the ground-motion exceedance probability used in the current AS1170.4 be reviewed in light of the recent hazard assessment and the expected performance of modern buildings for rarer ground motions.
Whilst adjusting the AS1170.4 exceedance probability level would be a major departure from previous earthquake loading standards, it would bring it into line with other international building codes in similar tectonic environments. Additionally, it would offer opportunities to further modernise how seismic demands are considered in Australian building design. In particular, the authors highlight the following additional opportunities: 1) the use of uniform hazard spectra to replace and simplify the spectral shape factors, which do not deliver uniform hazard across all natural periods; 2) updated site amplification factors to ensure continuity with modern ground-motion models, and; 3) the potential to define design ground motions in terms of uniform collapse risk rather than uniform hazard.
Estimation of seismic hazard at any location is an uncertain science. However, as our knowledge improves, our estimates of the hazard will converge on the actual – but unknowable – (time independent) hazard. It is therefore prudent to regularly update the estimates of the seismic demands in our building codes using the best available evidence-based methods and models.

MRTAS Offshore NW Tasmania magnetic 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 MRTAS Offshore NW Tasmania magnetic grid geodetic has a cell size of 0.00167 degrees (approximately 163m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2008 by the TAS Government, and consisted of 43783 line-kilometres of data at 800m line spacing and 85m terrain clearance.

Australian Earthquakes 2014

A short animation video showing earthquakes occurring in Australia during 2014, as a timelapse. 
2014 was a relatively quiet year for Australian earthquakes. Most earthquake events measured less than magnitude 4, which is considered small and unlikely to cause damage. 
Only seven earthquakes in 2014 were magnitude 4.0 or larger and these were felt throughout the regions in which they occurred.  Although Australia, on average, tends to get one magnitude 5 per year, no earthquakes magnitude 5 or greater occurred in 2014.

Developing a 3D hydrogeological framework for Australia

Output Type: Exploring for the Future Extended Abstract

Short abstract: Australia is the driest inhabited continent on Earth and relies heavily on groundwater to support communities, industries, ecosystems and cultural values. Despite groundwater resources transcending state and territory boundaries, each jurisdiction operates under different legislative frameworks, policies and water management approaches, and accordingly coordination between jurisdictions is crucial to achieving the common goal of water security. Improving the alignment of water strategies between states and territories requires a national coordination of data collation with common standards and integration of subsurface geology, using a consistent and up-to-date 3D hydrogeological framework for better understanding of groundwater systems and flow pathways at regional to national scales. Despite ever increasing data availability in each jurisdiction there is a lack of comprehensive knowledge regarding cross-jurisdictional sedimentary architecture, aquifer extents and hydraulic connections. Geoscience Australia, through the Exploring for the Future program, is developing a consistent national chronostratigraphic framework to underpin the development of 3D (hydro)geological models which can be used to standardise hydrogeological classifications, update borehole stratigraphy and provide a basis for integrating diverse geoscientific datasets. By collaborating with jurisdictions to harmonise 3D geology nationally through correlation with the geological time scale, aquifer boundaries can be updated and shared with other collaborators such as the Bureau of Meteorology to ensure that national groundwater datasets are updated with the latest geological knowledge. This chronostratigraphic method is suitable for sedimentary basins and provides a consistent platform to support effective resource assessment and management, infrastructure planning, and environmental impact assessment at regional and national scales.

Australian Petroleum Systems. Barrow-Exmouth Sub-basins module

This module is part of the AGSO-APIRA Australian Petroleum Systems Project. 
Eight basin modules were examined which covered almost the entire North West Shelf, the Petrel Sub-basin, as well as the Papuan basin in PNG. 
Two relational databases were established containing the biostratigraphic data (STRATDAT) and reservoir, facies and hydrocarbon shows data (RESFACS). These databases were linked by application programs which allow time series searching using geologically intelligent routines. 
Petroleum systems analyses were conducted on each area, with key results focussing upon the comparison of source quality and timing of generation between similar systems in different areas.
