King Island, Tas, 1987 (P543), 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 King Island, Tas, 1987 (P543), radiometric line data, AWAGS levelled were acquired in 1987 by the TAS Government, and consisted of 1700 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.

Paleogeothermal gradients in Australia: key to 4-D lithosphere mapping

Empirical paleogeotherms constructed from geothermobarometry of deep-seated xenoliths and garnet Â± chromite concentrates from basalts, lamproites and kimberlites around Australia reveal regions of different paleogeothermal signatures. Differences between the tectonically young eastern areas and the cratonic western part of the Australian continent correspond to those shown on a large scale by long-wavelength magnetic data, which integrate the total magnetic signature from the lithospheric column where temperatures are below the Curie Point.  Surface heat-flow measurements may not reflect deeper geothermal gradients and model-dependent extrapolations to lower crust and mantle depths must be used cautiously. In eastern Australia, where xenolith data are available (coinciding with the basaltic provinces), there is a remarkably consistent geotherm, which is independent of the age of the basaltic volcanism. This inflected (advective) geotherm is higher than  conventional ocean basin geotherms and reflects thermal perturbation associated with volcanic episodes.  It records the thermal state at the time of the particular volcanic activity, and decays towards a conductive geotherm with a relaxation time of 40-50 m.y.  Data from the eastern craton margin (in South Australia and western New South Wales) indicate significant changes in the thermal state through time, while Archaean and Proterozoic areas in Western Australia reflect typically low geotherms.  Knowledge of a robust geotherm for a specific lithospheric column can be used to construct a realistic distribution of rock types with depth.  This lithospheric column provides constraints for the geologically meaningful interpretation of geophysical data and for placing geochemical and mantle process information in a spatial context.

Application of European Macroseismic Scale 1998 in the Asia-Pacific region

The paper presents the application of European Macroseismic Scale - 1998 (EMS-98) in assessing building vulnerability and to construct damage scenarios for the building stock in Padang (Indonesia) and Muzaffarabad (Pakistan).  Typical building types in Indonesia and Pakistan are defined and compared to the standard construction types of the EMS-98.
The inventory of 4,000 buildings in Padang was acquired from the 2009 Padang Region Damage Survey undertaken following the 30th September, 2009 West Sumatra Earthquake and supported by the Australia-Indonesia Facility for Disaster Reduction. During the survey, the building stock in Padang was classified into a schema consisting of 54 types and observed damages were categorised into 9 severities. An effort was made to map the building stock and observed damages from the survey outcomes to EMS-98 definitions to perform a scenario.  
The inventory of 750 buildings in Muzaffarabad was obtained from a field survey carried out after the 2005 Kashmir earthquake that struck the city and its hinterland, and subsequently updated in 2007 after conducting more surveys. The surveys documented the key building features so that the primary parameters affecting vulnerability and typical failure mechanisms could be identified. 
This study highlights the flexibility and robustness that EMS-98 offers for use outside of the European region and describes the limitations and possible improvements in the current version of the scale for global application. These include the addition of new building types (e.g., dhajji, brick veneer and mixed material construction), inclusion of a very high vulnerability class (A-), consideration of building vintage and storey class in vulnerability assignment and damage description for wooden structures. Treatment of subjectivity and uncertainty are the key areas requiring more attention in making improvements in EMS-98 and making it a global scale.

The 2018 Lake Muir earthquake sequence, south west Western Australia: insights into the characteristics of Australian stable continental region earthquakes

Modern geodetic and seismic monitoring tools are enabling study of moderate-sized earthquake sequences in unprecedented detail. Here we use a variety of methods to examine surface deformation caused by a sequence of earthquakes near Lake Muir in Southwest Western Australia in late 2018. A shallow MW 5.3 earthquake near Lake Muir on the 16th of September 2018 was followed on the 8th of November by a MW 5.2 event in the same region. Focal mechanisms produced for the events suggest reverse and strike slip rupture, respectively. Recent improvements in the coverage and observation frequency of the Sentinel-1 Synthetic Aperture Radar (SAR) satellite in Australia allowed for the timely mapping of the surface deformation field relating to both earthquakes in unprecedented detail. Interferometric Synthetic Aperture Radar (InSAR) analysis of the events suggest that the ruptures are in part spatially coincident. Field mapping, guided by the InSAR results, revealed that the first event produced an approximately 3 km long and up to 0.5 m high west-facing surface rupture, consistent with slip on a moderately east-dipping fault. Double difference hypocentre relocation of aftershocks using data from rapidly deployed seismic instrumentation confirms an easterly dipping rupture plane for the first event. The aftershocks are predominantly located at the northern end of the rupture where the InSAR suggests vertical displacement was greatest. The November event resulted from rupture on a NE-trending strike slip fault. Anecdotal evidence from local residents suggests that the southern part of the September rupture was ‘freshened’ during the November event, consistent with InSAR results, which indicate that a NW-SE trending structural element accommodated deformation during both events. Comparison of the InSAR-derived deformation field with surface mapping and UAV-derived digital terrain models (corrected to pre-event LiDAR) revealed a surface deformation envelope consistent with the InSAR for the first event, but could not discern deformation unique to the second event.

West Pilbara 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 West Pilbara magnetic grid geodetic has a cell size of 0.001 degrees (approximately 100m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1995 by the WA Government, and consisted of 75096 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of 13C isotope in sediments

This resource contains a predicted 13C isotope standard error grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The predicted 13C isotope standard error grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.
