Seismic vulnerability functions for Australian buildings by using GEM empirical vulnerability assessment guidelines

Australia has a low to moderate seismicity by world standards. However, the seismic risk is significant due to the legacy of older buildings constructed prior to the national implementation of an earthquake building standard in Australia. The 1989 Newcastle and the 2010 Kalgoorlie earthquakes are the most recent Australian earthquakes to cause significant damage to unreinforced masonry (URM) and light timber frame structures and have provided the best opportunities to examine the earthquake vulnerability of these building types. 
This paper describes the two above mentioned building types with a differentiation of older legacy buildings constructed prior to 1945 to the relatively newer ones constructed after 1945. Furthermore, the paper presents method to utilise the large damage and loss related data (14,000 insurance claims in Newcastle and 400 surveyed buildings in Kalgoorlie) collected from these events to develop empirical vulnerability functions. The method adopted here followed the GEM Empirical Vulnerability Assessment Guidelines which involves preparing of a loss database, selecting an appropriate intensity measure, selecting and applying a suitable statistical approach to develop vulnerability functions and the identification of optimum functions. The adopted method uses a rigorous statistical approach to quantify uncertainty in vulnerability functions and provides an optimum solution based on goodness-of-fit tests.
The analysis shows that the URM structures built before 1945 are the most vulnerable to earthquake with post 1945 URM structures being the next most vulnerable. Timber structures appear to be the least vulnerable, with little difference observed in the vulnerability of timber buildings built before or after 1945. Moreover, the older structures (both URM and timber) depict exhibit more scatter in results reflecting greater variation in building vulnerability and performance during earthquakes. The analysis also highlights the importance of collecting high quality damage and loss data which is, not only a fundamental requirement for developing empirical vulnerability functions, and but is also useful in validating analytically derived vulnerability functions. The vulnerability functions developed herein are the first publically available functions for Australian URM and timber structures. They can be used for seismic risk assessment and to focus the rm a basis for development ofing retrofit strategies to reduce the existing earthquake risk.

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC42km50kmRes)

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 2019 Total magnetic Intensity (TMI) grid of Australia has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the sixth edition was released in 2015, data from 234 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. The new grid was derived from a re-levelling of the national magnetic grid database. The survey grids were levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS), which serves as a baseline to constrain long wavelengths in the final grid. It is estimated that 33 500 000 line-kilometres of survey data were acquired to produce the 2019 grid data, about 2 000 000 line-kilometres more than for the previous edition. 
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 Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC42km50kmRes) is a pseudocolour image of the TMI grid of the Magnetic Anomaly Map of Australia, Seventh Edition, 2019.
This grid has a cell size of 0.00083 degrees (approximately 88m). This pseudocolour image shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The image can also be used to locate structural features such as dykes.

Helium from Natural Gas

The noble gas helium is a critical commodity of strategic importance to Australia and is found within the numerous natural gas fields in onshore and offshore basins. Helium’s availability is intimately linked with the liquefied natural gas (LNG) process where it is recovered from the waste “tail gas” stream enriched in nitrogen and helium.
Geoscience Australia has compiled a geochemical inventory of the composition of proven gas fields in response to the predicted global shortage of helium by 2021. By undertaking this molecular and isotopic analysis of natural gases, Geoscience Australia has identified an untapped resource potential of helium in Australia’s gas fields. The United States, Qatar and Algeria have the highest global resource estimates and production of helium.

Processed sub-bottom profiler data - Seabed environments and shallow geology of the Vlaming Sub-basin, offshore Perth Basin (GA0334)

In March and April, 2012, Geoscience Australia undertook a seabed characterisation survey, aimed at supporting the assessment of CO2 storage potential of the Vlaming Sub-basin, Western Australia (Survey GA0334). The survey, undertaken as part of the National CO2 Infrastructure Plan program was targeted to provide an understanding of the link between the deep geological features of the area and the seabed, and connectivity between them as possible evidence for seal integrity. Data was acquired in two sections of the Rottnest Shelf lying above the regional seal - the South Perth Shale - and the underlying potentially CO2-suitable reservoir, the Gage Sandstone. Seabed samples were taken from 43 stations, and included 89 seabed grab samples. 
A total of 653 km2 of multibeam and backscatter data was obtained. Chirper shallow sub-bottom profile data was acquired concurrently. 6.65 km2 of side-scan sonar imagery was also obtained. The two surveyed areas, (Area 1 and Area 2), are set within a shallow sediment starved shelf setting. Area 2, situated to the southwest of Rottnest Island, is characterised by coralline red algal (rhodolith) beds, with ridges and mounds having significant rhodolith accumulations. The geomorphic expression of structural discontinuities outcropping at the seabed is evident by the presence of linear fault-like structures notable in Area 1, and north-south trending lineaments in Area 2. North-south trending structural lineaments on the outer section of Area 2 have in places, mounds standing 4-5 m above the seafloor in water depths of 80-85 m. 
This dataset, aquired by Fugro Pty Ltd, comprises sub-bottom profiles processed as shallow, high-resolution acoustic data (SEG-Y format) and navigation files (P190).

Are we ready for the next big shake? : Evidence to inform risk mitigation

Natural disasters impact Australian communities every year.  They disrupt communities and, on average, cause billions in losses annually in response activity, recovery needs and economic disruption.  While the more frequent flood and wind events feature prominently, Australian earthquakes can cause catastrophic consequences that are generally not well understood and can be difficult to manage when they occur.  Do we understand the demands they can impose?  Are we adequately informed as to the options for reducing this risk?  Are we really ready for the next big shake?
Earthquake risk is the combination of the hazard severity, the assets exposed and the susceptibility of these to severe ground motion.  In bringing these three components together an understanding can be developed of the potential impacts of credible earthquake events that are presently beyond Australia’s settled experience.  For emergency managers it can provide insights into events they have not encountered to enable planning for the management of similar.  They can also provide information in a quantified form that can inform decisions and incentives to invest in changing earthquake risk through vulnerability reduction and improved community resilience.  There is a particular need for targeted investment as earthquake hazard has not been considered in the design of both buildings and critical infrastructure for most of Australia’s settled history.
This paper describes collaborative research being undertaken to better understand more holistically the consequences of the next big shake.  The very non-linear nature of impact severity with longer average recurrence intervals is highlighted and how this information is supporting emergency management planning is described.  The paper also describes how this research is developing knowledge of the factors behind the vulnerability in the built environment and the opportunities to mitigate this.  The software tool named System for Infrastructure Facility Resilience Analysis (SIFRA) is described.  It enables infrastructure facility components to be examined in the context of earthquake vulnerability, system criticality, repair cost and restoration time.  The sensitivities in developing information with infrastructure managers are outlined and how these are being addressed is discussed in gaining access to and sharing data, information and specialist expertise. Finally, a research project focussed on earthquake mitigation strategies for vulnerable buildings is highlighted as an example of local engagement in addressing community risk.
