Site characterisation of twelve seismic monitoring stations in South East Victoria, Australia

Spatially heterogeneous ground motions generated by earthquakes are partially attributed to near surface conditions (i.e., site response), quantification of which enables the selection and calibration of region-specific ground-motion models (GMMs) used in seismic hazard assessments. The 21 September 2021 MW 5.9 earthquake, the largest magnitude earthquake instrumentally recorded in Victoria, was well recorded across the University of Melbourne’s seismic network (UMSN) in eastern Victoria, providing a rare opportunity to assess the utility of published GMMs for large-magnitude earthquakes, and thereby improve seismic hazard assessment in the region. To benchmark these ground-motion recordings, estimating seismic site response is required, in support of which we present results of site characterisation for 12 UMSN. 
The analysis of surface wave components of ambient noise using microtremor surveys can provide well constrained shear-wave velocity models for the uppermost few hundred metres of the subsurface. By combining spatially averaged coherency (SPAC) and frequency-wavenumber (FK) array techniques, we retrieve multimode Rayleigh and Love phase velocity dispersion curves and Rayleigh-wave ellipticity, which we jointly invert for site-specific, near-surface shear wave velocity models. Previous studies demonstrate that incorporating dispersion of Love waves in the inversions provide stronger constraints of the uppermost shear-wave velocity structure. These inversions produced a set of representative 1-D shear wave velocity profiles for each site, which will contribute to the Australian Ground-Motion Database - a national repository of earthquake ground-motion data and site metadata for engineering applications.

The timing of mineralization in the Pilbara Craton, Western Australia

Mineralizing events in the North Pilbara terrain of Western Australia occurred between 3490 and 2700 Ma and include the oldest examples in the world of many ore deposit types. These events were pulsed and associated with major volcano-plutonic episodes (volcanic-hosted massive sulfide, porphyry Cu, Sn-Ta pegmatite, mafic-ultramafic-hosted Ni-Cu-PGE, and epithermal deposits) and deformation events (lode Au deposits). In many cases, the mineralizing events are associated with extension, either in rifts, pull-apart or back-arc basins, or as the consequence of doming associated with granitoid diapirism. 
Although mineralizing events occurred throughout the evolution of the North Pilbara terrain, the largest deposits are related to the development of the Mallina basin, which is located between the older East and West Pilbara granite-greenstone terranes. Four volcano-plutonic and three deformation events occurred in and around the Mallina basin between 2950 and 2840 Ma. Mineralization in the East and West Pilbara granite-greenstone terranes is less intense and occurred over a much longer period. 
Compared to other Archean granite-greenstone terrains, the North Pilbara terrain is poorly endowed; the only known world-class deposit in this region is the Wodgina Ta-Sn pegmatite deposit, but large iron ore deposits are being mined in the northeastern North Pilbara terrain. The long history of crustal development and slow rate of crustal growth may be responsible for the diversity of mineral deposits and could account for the apparent poor endowment of the North Pilbara terrain.

Collie Area Gravity 1982-1991 (P199059), 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 Collie Area Gravity 1982-1991 (P199059) contains a total of 528 point data values acquired at a spacing between 500 and 1000 metres. The data is located in WA and were acquired in 1990, under project No. 199059 for Geological Survey of Western Australia (GSWA).

NSW DMR, Discovery 2000, AREA P, NARRABRI, NSW 2000 (P753), magnetic line data, AWAGS levelled

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.
 These line dataset from the NSW DMR, Discovery 2000, AREA P, NARRABRI, NSW 2000 survey were acquired in 2000 by the NSW Government, and consisted of 43190 line-kilometres of data at 400m line spacing and 80m 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.

York Mitigation Grants Flyer

Even though the Australian continent sits within a major tectonic plate, it is affected by earthquakes. Each year, more than 100 earthquakes measuring 3.0 or more on the Richter scale are felt across Australia, with the majority affecting Western Australia—more than X since 1900. Many of these earthquakes are focused around York. Despite the prevalence of earthquakes in the region, the risks have not consistently been recognised during building design and construction. This means many buildings - particularly older masonry buildings - are susceptible to damage from earthquakes.
