Being Prepared for Earthquakes

You may not realise it but, on average, Australia is rattled every few days by
an earthquake of magnitude 3 or above. We don’t feel every small tremor that
happens, but the larger earthquakes are powerful enough to cause serious
damage to buildings and infrastructure, putting our community’s safety at risk.

Well-log Data, Officer Basin, South Australia

The Officer Basin is a poorly exposed Neoproterozoic and Early Palaeozoic intracratonic basin in south central Australia. The Officer Basin Project was developed co-operatively between the Australian Geological Survey Organisation (AGSO) and the Department of Mines and Energy, South Australia (MESA) as part of the National Geoscience Mapping Accord (Lindsay &amp; others, 1991; Leven &amp; Barton, 1991). The main AGSO objectives were to evaluate the resource potential of the region and promote  petroleum exploration by developing a depositional and post-depositional model of the basin.
These objectives were accomplished by means of an integrated basin analysis involving the reassessment of existing seismic, well-log and potential field data and the gathering of approx- imately 550 km of new seismic data. The results of this work have been assembled as a major basin atlas (Lindsay, in prep.). This record summarises details of the analysis and reassessment of well-log data from the South Australian part of the basin.

Cambrian convergent margin configuration in the Delamerian Orogen of mainland Australia

Output type: Exploring for the Future Extended Abstract  

Short Abstract: The Delamerian Orogen, with a length of ~1000 km on mainland Australia and a proven potential to host mineralisation, represents an evolving exploration opportunity. However, uncertainty surrounding the age and tectonic setting of the orogen is a barrier to confident exploration in frontier covered regions, such as the Loch Lilly-Kars Belt in western New South Wales and South Australia. A major area of uncertainty is the configuration and extent of the Cambrian convergent-margin system and lateral variations thereof. In this study, we highlight multidisciplinary data from new and legacy sources, including lithology, geochronology, geochemistry, potential-field geophysics, deep-crustal seismic, and magnetotelluric data that permit a revised interpretation of the geological framework for the Delamerian Orogen in mainland Australia, with an emphasis on the covered, central part of the system. These data indicate that a largely continuous, east-facing volcanic arc developed in the Delamerian Orogen in the Cambrian. The arc transitions from exhibiting a strong continental affinity in the Koonenberry Belt to having less continental affinity in the Grampians-Stavely Zone of Victoria. The Loch Lilly-Kars Belt is interpreted to have occupied a volcanic arc to incipient back-arc position in the middle Cambrian.&nbsp;

The 2018 Lake Muir earthquakes: Australia’s ninth surface rupturing earthquake sequence in 50 years

A shallow MW 5.3 earthquake near Lake Muir in southwest Western Australia on the 16 September 2018 was followed on the 8 November by a co-located MW 5.2 event in the same region. Sentinel-1 synthetic aperture radar interferograms (InSAR) allowed for the timely identification and mapping of the surface deformation relating to both earthquakes. Field mapping, guided by the InSAR observations, revealed that the first event produced an approximately 3 km-long and up to 0.4 m-high west-facing surface rupture. Five seismic rapid deployment kits (RDKs) were installed in the epicentral region within three days of the 16 September event. These data, telemetered to Geoscience Australia’s National Earthquake Alerts Centre, have enabled the detection and location of more than 750 dependent events up to ML 4.6. Preliminary joint hypocentre relocation of aftershocks using data from RDKs confirms an easterly dipping rupture plane for the first MW 5.3 event.
The main shocks were recorded throughout the Australian National Seismic Network, in addition to a local broadband network in the Perth Basin operated by University of Texas at Dallas and the University of Western Australia. These data indicate large long-period ground-motions due to Rg phases and basin amplification. The two main shocks were widely felt within the region, including the Perth metro region (300 km away), with over 2400 online felt reports for the 8 November event.
The Lake Muir sequence represents the ninth recorded surface rupturing earthquake in Australia in the past 50 years. All of these events have occurred in the Precambrian cratonic terranes of western and central Australia, in unanticipated locations. Paleoseismic studies of these ruptures found no evidence for regular recurrence of large events on the underlying faults. The events might therefore be considered “one-offs” at timescales of significance to typical probabilistic seismic hazard studies.

Northwest Northern Territory Seismic Survey (L214) shape files

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources.  By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. 
The Paleo to Mesoproterozoic Birrindudu Basin is an underexplored frontier basin located in northwestern Northern Territory and northeastern Western Australia. The Birrindudu Basin is a region of focus for the second phase of the EFTF program (2020–2024) as it contains strata of similar age to the prospective McArthur Basin, South Nicholson region and Mount Isa Province, but remains comparatively poorly understood. 
Geoscience Australia (in collaboration with the Northern Territory Geological Survey) acquired around 700 line-kms of deep crustal reflection seismic data across northwest Northern Territory encompassing not only the frontier Birrindudu Basin but adjacent highly prospective regions, such as the Tanami. 
This ecat record releases the final survey route shapefiles, noting that some segments were not acquired due to site access restrictions. 
Seismic field data will be published in the near future release following completion of in-house QA/QC protocols

Connecting climate and catastrophe models for tropical cyclones

Queensland Fire and Emergency Services are leading the development of consistent risk information relating to the potential impacts of disasters across Queensland. The stated aim is to ensure all local, district and state government stakeholders have access to the same information to guide risk-based planning in the preparation for natural disasters. This extends to future projections natural hazard activity, including tropical cyclones (TC), in the Queensland region. 
To achieve this last objective, Queensland’s Department of Environment and Science (DES) have undertaken a program of regional climate simulations, with a view to informing long-term planning decisions. When it comes to TCs – a major cause of disasters in Queensland – many of the stakeholders want to answer the question: “How many severe tropical cyclones will the future hold for us?”, or similar questions around the likelihood of TC occurrence.
To answer this, DES and Geoscience Australia are interrogating the regional climate simulations to extract Tropical Cyclone-Like Vortices (TCLVs). The behaviour of these TCLVs is then analysed to understand changes in frequency, intensity and spatial distribution. The TCLVs – with some additional bias corrections - can also be used as input to stochastic models that can provide probabilistic wind hazard information across the entire state of Queensland. 
In this paper we demonstrate the challenges of extracting TCLVs from regional climate models and the bias corrections required to make useful projections of TC activity into the future.
