Clermont, QLD, 1989 (P1154), 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 Clermont, QLD, 1989 survey were acquired in 1989 by the QLD Government, and consisted of 15875 line-kilometres of data at 400m line spacing and 60m 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.

Apples and Oranges: Developing a consistent catalog of local magnitudes for the National Seismic Hazard Assessment of Australia

Modern probabilistic seismic hazard assessments rely on earthquake catalogs consistently expressed in terms of moment magnitude, MW. However, MW is still not commonly calculated for small local events by many national networks. The preferred magnitude type calculated for local earthquakes by Australia’s National Earthquake Alerts Centre is local magnitude, ML. For use in seismic hazard forecasts, magnitude conversion equations are often applied to convert ML to MW. Unless these conversions are time-dependent, they commonly assume that ML estimation has been consistent for the observation period. While Australian-specific local magnitude algorithms were developed from the late 1980s and early 1990s, regional, state and university networks did not universally adopt these algorithms, with some authorities continuing to use Californian magnitude algorithms. Californian algorithms are now well-known to overestimate earthquake magnitudes for Australia.  Consequently, the national catalogue contains a melange of contributing authorities with their own methods of magnitude estimation.
The challenge for the 2018 National Seismic Hazard Assessment of Australia was to develop a catalog of earthquakes with consistent local magnitudes, which could then be converted to MW. A method was developed that corrects magnitudes using the difference between the original (inappropriate) magnitude formula and the Australian-specific corrections at a distance determined by the nearest recording station likely to have recorded the earthquake. These corrections have roughly halved the rates of ML 4.5 earthquakes in the Australian catalogue. 
To address ongoing challenges for catalog improvement, Geoscience Australia is digitising printed and hand-written observations preserved on earthquake data sheets. Once complete, this information will provide a valuable resource that will allow for further interrogation of pre-digital data and enable refinement of historical catalogs.

Cost effective mitigation strategy development for flood prone buildings -Preliminary Building Schema

Within Australian communities there is a wide range of building types.  These vary in many attributes that include floor area, number of storeys, age, architectural style, fit out quality, construction material types and the level of maintenance. For mitigation research it is necessary to take this variety of building types and spatial distribution and discretise it into building classes or categories of similar, if not identical, vulnerability.  This 'pigeon holing' strategy makes research on impact, risk and mitigation more tractable in that vulnerabilities can be assigned to each class with the reduced variability within the class captured in the uncertainty of the model.  Available exposure information can also be mapped to the schema along with building types that can benefit from retrofit interventions.
This report presents the preliminary building schema proposed for the Cost Effective Mitigation Strategy Development for Flood Prone Buildings BNHCRC project. The report discusses the utility of a building schema and which building attributes are important for distinguishing between houses of differing vulnerabilities in the Australian building stock.
The proposed schema divides each building into foundations, bottom floor, upper floors (if any) and roof to describe its vulnerability. Through this arrangement it is made possible to assess vulnerability of structures with different construction material used in different floors and also to assess vulnerability of tall structures where only bottom floors are supposed to be inundated. The schema classifies each floor system based on the following attributes:
-   Construction period
-   Fit-out quality
-   Storey height
-   Bottom floor system
-   Internal wall material
-   External wall material
Allowing for combinations that are invalid in an Australian context, the draft schema defines 60 discrete vulnerability classes based on the above mentioned attributes. Furthermore, the schema proposed 6 roof types based on material and pitch of the roof.
This proposed schema is the initial categorisation of residential structures as to vulnerability class for this project. It is expected to change and be refined as the project is taken forward and the specific building types for retrofit research are identified. The concept of 'nestability' may be subsequently used where mitigation research focuses on several building types that fall within a single broader category and become sub-classes. The draft schema has been developed in recognition of the current and projected ability to define national building exposure and of the parallel BNHCRC mitigation projects examining vulnerability to earthquake and severe wind. While vulnerability schema are hazard specific, alignment has been sought with the schemas for other hazards where possible.

AUSGeoid98 v.1.0 data files: Ooldea (sh52-12)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Lithological correlations of Adelaidean glaciogenic rocks in parts of the Amadeus, Ngalia, and Georgina Basins

Adelaidean glaciogenic sediments, representing two major glaciations, are widespread in three central Australian basins. Recognition of distinguishable marker dolomites, identical to those found above lower and upper tillites in the Adelaide Geosyncline, South Australia, has led to a revision of the Adelaidean stratigraphy of the Amadeus Basin. There the earlier glaciation is represented by the Areyonga Formation. The term Areyonga Formation is here restricted to the previously unnamed lower member (diamictite, conglomerate, sandstone, silt-stone, dolomite) as originally defined in the central-western sections, where it is discontinuous; and corresponds to the whole of what has been mapped as Areyonga Formation in the extreme east. In each area it is capped by a sequence of thinly laminated, dark grey dolomite and silt-stone. The former upper sandstone member of the Areyonga Formation lies with inferred disconformity on various older units. It is probably a non-glacial lateral equivalent of the glaciogenic Olympic Formation (formerly Member) in the east, which records the younger of the two glaciations. The Olympic Formation is overlain by a typical upper marker dolomite, which is pink to buff-coloured, laminated and flaggy. A thin lower tillite, with typical lower marker dolomite, was recognised for the first time in the Ngalia Basin. It lies below a shale sequence beneath the upper tillite (Mount Doreen Formation), which has a typical upper marker dolomite. In the Georgina Basin, the diamictites and varved siltstones of the Field River Beds, recording the earlier glaciation, are capped by an identical lower marker dolomite. Glacials at Central Mount Stuart and at Nancy Hill are of uncertain stratigraphic position, but lithological associations suggest a comparison with the earlier of two Sturtian (lower) tillites in South Australia. These correlations indicate remarkable persistance of certain marker lithologies, and the recurrence of extremely similar lithologic successions, across much of the late Precambrian platform. Presently available isotopic and biostratigraphic data are imprecise and subject to many doubts and qualifications, but are consistent with the view that each glaciation was approximately synchronous in the basins considered. New nomenclature for some upper Adelaidean units in the Amadeus and Ngalia Basins is formalised in the Appendix.
