Permo-Carboniferous palynology of Gondwanaland: progress and problems in the decade to 1980

The decade 1970-80 has seen the emergence of new regional, palynologically based biostratigraphic schemes, or the modification of existing ones, from late Carboniferous through Permian sequences on the major, now dispersed continents of Gondwanaland. Schemes comprising loosely defined assemblage zones and/or interval zones have been published for eastern and western Australia, Antarctica, India, south, east and west Africa, and South America. Inter-regional correlation based on these zones is for the most part of a broad kind, but the beginnings of a widely applicable chronostratigraphy are discernible, and relatively high-resolution correlation is possible between selected intervals in Australia, India and southern Africa. During the decade there has been some emphasis on the palynology of late Palaeozoic glacial deposits, with data becoming available from all major continents. These data do not support the idea of a sequential migration of glacial centres across Gondwanaland. Information has also become available concerning the palynology of sediments transitional between the Permian intervals of coal measure sedimentation and the overlying red-bed sequences; palynological data suggest that the Permian-Triassic boundary lies well above the youngest coal measures, at least in India and eastern Australia. Palynological information accumulated during the decade points also to the existence of phytogeographic subprovinces within the Glossopteris-dominated Permian vegetation of Gondwanaland.

Towards an updated national seismic assessment for Australia

Geoscience Australia has produced a draft National Seismic Hazard Assessment (NSHA18),
together with contributions from the wider Australian seismology community. This paper provides
an overview of the provisional peak ground acceleration (PGA) hazard values and discusses
rationale for changes in the proposed design values at the 1/500-year annual exceedance probability (AEP) level relative to Standards Australia’s AS1170.4–2007 design maps. The NSHA18 update yields many important advances on its predecessors, including: consistent expression of earthquake magnitudes in moment magnitude; inclusion of epistemic uncertainty through the use of third-party source models; inclusion of a national fault-source model; inclusion of epistemic uncertainty on fault-slip-model magnitude-frequency distributions and earthquake clustering; and the use of modern ground-motion models through a weighted logic tree framework.
In general, the 1/500-year AEP seismic hazard values across Australia have decreased relative to
the earthquake hazard factors the AS1170.4–2007, in most localities significantly. The key reasons for the decrease in seismic hazard factors are due to: the reduction in the rates of moderate-to-large earthquakes through revision of earthquake magnitudes; the increase in b-values through the conversion of local magnitudes to moment magnitudes, particularly in eastern Australia, and; the use of modern ground-motion attenuation models.
Whilst the seismic hazard is generally lower than in the present standard, we observe that the
relative proportion of the Australian landmass exceeding given PGA thresholds is consistent with
other national hazard models for stable continental regions.

GSQ Munduberra Qld total count grid geodetic

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSQ Munduberra Qld total count grid geodetic has a cell size of 0.00096 degrees (approximately 102m) and shows the terrestrial dose rate of the Rockhampton 1 &amp; 2, Monto &amp; Munduberra, 1994-1995, Qld,AIRDATA. The data used to produce this grid was acquired in 1994 by the QLD Government, and consisted of 156236 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Tanami EW 5ZA - TMI RTP grid (AWAGS)

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 magnetic grid has a cell size of 0.00018 degrees (approximately 20m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2018 by the NT Government, and consisted of 1547 line-kilometres of data at 100m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid. This survey grid is essentially levelled to AWAGS.The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey.

AUSGeoid98 v.1.0 data files: Gilgandra (sh55-16)

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.

Observations on Tornado Damage to Residential Structures in Bendigo

Post-disaster data collection is a vital component of natural hazard assessment model development. Surveys of this type provide insights into the vulnerabilities of different building types to various hazards and may, in some instances, furnish valuable calibration data for verifying vulnerability models. The Risk Research Group of GA is presently developing and adapting multi-hazard vulnerability models for Australian structures that will be ultimately realised in a national risk assessment methodology. As part of the model development Geoscience Australia has carried out a number of post-disaster reconnaissance exercises including a systematic study of the wind damage caused by the May 2003 Bendigo tornado event. Residential structures of various type and ages were surveyed and contemporary brick veneer construction was found to represent the largest single group. The survey findings for this type of residential construction, along with an associated damage costing exercise that followed, are herein described.

Revisiting TC Vance – learning from the past to inform the future

In March 1999, TC Vance swept through Exmouth, with the eye wall of the cyclone passing directly over the township generating gusts to 267 km/h. Around 10% of residential houses showed structural failure, with some types of housing experiencing significantly greater damage. By revisiting the impacts of TC Vance, we hope to guide thinking of emergency managers and local government on planning for when another category 5 TC strikes Exmouth. 
Using the best track information provided by the Bureau of Meteorology, we simulate the wind field of TC Vance using Geoscience Australia’s Tropical Cyclone Risk Model (TCRM), incorporating the local effects of topography, terrain and shielding afforded by neighbouring structures. This simulation is validated against observations of peak wind speed recorded at Learmonth Airport and other regional weather stations. 
The impacts of TC Vance are calculated for the present building stock in Exmouth, which has grown by nearly a third since 1999. Modern residential buildings perform very well, in line with the performance levels established by the wind loading standards for the region. Some groups of older buildings – specifically the U.S. Navy block houses that survived TC Vance unscathed – also perform very well. 
The analysis shows the town of Exmouth would still suffer substantial impacts, with around 700 buildings likely to suffer moderate to complete damage. This translates to around 1400 people, with at least half of those requiring temporary accommodation in the days and weeks immediately after the cyclone.
These types of  analysis help to reduce uncertainty and enhances decision-making for emergency services, enabling a more proportional response for rescue, damage assessments and initial recovery at the State, regional and local levels. From a strategic perspective it can also be used to identify and verify current and future capability needs for agencies involved in managing the cyclone hazard.
