Surface-Rupturing Historical Earthquakes in Australia and Their Environmental Effects: New Insights from Re-Analyses of Observational Data

We digitize surface rupture maps and compile observational data from 67 publications on ten of eleven historical, surface-rupturing earthquakes in Australia in order to analyze the prevailing characteristics of surface ruptures and other environmental effects in this crystalline basement-dominated intraplate environment. The studied earthquakes occurred between 1968 and 2018, and range in moment magnitude (Mw) from 4.7 to 6.6. All earthquakes involved co-seismic reverse faulting (with varying amounts of strike-slip) on single or multiple (1–6) discrete faults of ≥ 1 km length that are distinguished by orientation and kinematic criteria. Nine of ten earthquakes have surface-rupturing fault orientations that align with prevailing linear anomalies in geophysical (gravity and magnetic) data and bedrock structure (foliations and/or quartz veins and/or intrusive boundaries and/or pre-existing faults), indicating strong control of inherited crustal structure on contemporary faulting. Rupture kinematics are consistent with horizontal shortening driven by regional trajectories of horizontal compressive stress. The lack of precision in seismological data prohibits the assessment of whether surface ruptures project to hypocentral locations via contiguous, planar principal slip zones or whether rupture segmentation occurs between seismogenic depths and the surface. Rupture centroids of 1–4 km in depth indicate predominantly shallow seismic moment release. No studied earthquakes have unambiguous geological evidence for preceding surface-rupturing earthquakes on the same faults and five earthquakes contain evidence of absence of preceding ruptures since the late Pleistocene, collectively highlighting the challenge of using mapped active faults to predict future seismic hazards. Estimated maximum fault slip rates are 0.2–9.1 m Myr−1 with at least one order of uncertainty. New estimates for rupture length, fault dip, and coseismic net slip can be used to improve future iterations of earthquake magnitude—source size—displacement scaling equations. Observed environmental effects include primary surface rupture, secondary fracture/cracks, fissures, rock falls, ground-water anomalies, vegetation damage, sand-blows/liquefaction, displaced rock fragments, and holes from collapsible soil failure, at maximum estimated epicentral distances ranging from 0 to ~250 km. ESI-07 intensity-scale estimates range by ± 3 classes in each earthquake, depending on the effect considered. Comparing Mw-ESI relationships across geologically diverse environments is a fruitful avenue for future research.

Pre-cruise Report - Prydz Bay - MacRobertson Shelf and Kerguelen Plateau, February-April 1995 : AGSO Cruise 149, R.V. Aurora Australis

This record describes the background, aims and methods to be employed in the second AGSO/Antarctic Co-operative Research Centre/ANARE marine geoscience program in Prydz Bay and the Mac. Robertson Shelf. The cruise program consists of activities aimed at understanding modern sedimentary processes on the Antarctic margin, understanding the Plio-Pleistocene environmental history of the region and obtaining samples from the Kerguelen Plateau to illuminate the history of watermass reorganisation in the Southern Ocean during Quaternary. Climate change episodes.
The cruise will address goals set by the Antarctic CRC Natural Variability (sediments) sub-program, which are to promote a better understanding of global climate change by providing statements of the Antarctic and Southern Ocean palaeoenvironments over the following time intervals:
(A)0-10,000 years (post-glacial warming)
(B)0-160,000 years (last glacial cycle)
(C) 0-5,000,000 years (Pliocene "warming" of Antarctica)
These goals will be achieved by studying the Antarctic and Southern Ocean sedimentary record for evidence of Antarctic ice sheet and Southern Ocean circulation changes.
The development of accurate predictive models of climate change requires an understanding of the behaviour and interaction of components of global climate systems. The East Antarctic Ice Sheet is one such major component so that the study of its behaviour during past climatic fluctuations should provide key guidelines for climatic modelling. Sediments deposited in Prydz Bay contain a record of icesheet fluctuations because this area is located at the downstream end of the largest outlet glacier flowing from the East Antarctic Ice Sheet, the Lambert Glacier-Amery Ice shelf.
Another major component of the global climate system is the Southern Ocean. Water masses of the Southern Ocean play a pivotal role in world climate by absorbing, transporting and releasing heat and by transferring oxygen, nutrients and CO2 to and from the deep ocean. In
this context, the Kerguelen Plateau has accumulated sedimentary sequences that will contain records of how the polar front and its associated water masses have varied between glacial and interglacial periods.
The three geographical features targeted for study during the cruise are: (A) the trough-mouth fan deposits adjacent to Prydz Bay; (B)sediment traps associated with deep, shelf-basins on the Mac. Robertson Shelf; and (C) depositional basins on the Kerguelen Plateau. In the following sections the existing data bases for these areas are discussed and the objectives for the 1995 cruise of Aurora Australis are presented.

BMR Yearbook

The BMR Yearbooks followed on from and retained the format of the final BMR Annual Report.  The 1977 yearbook did not use that word in its title, which was simply BMR77.  Later volumes followed this pattern, but added the subtitle: Yearbook of the Bureau of Mineral Resources, Geology and Geophysics, and in common usage they became known as the BMR (later AGSO) Yearbooks.

Regional magnetic and gravity responses of extensional sedimentary basins

The gravity and magnetic responses of extensional sedimentary basins vary wi th the stages of basin development.  The major observed gravity responses are regional gravity highs, reflecting crustal thinning, and gravity lows, reflecting low-density sediment infill.  Mafic bodies may develop beneath the area of maximum extension as a result of mantle depressurisation and crustal rupture.  These may cause regional magnetic anomalies and add to gravity highs.  The observed gravity field over a rifted area depends on the relative contributions of the sources of the gravity highs and lows.  The observed regional magnetic field depends on the degree of development of mafic bodies.

Mineral potential of the Archaean Pilbara and Yilgarn Cratons, Western Australia

There are two Archaean cratons in Western Australia, the Pilbara Craton and the Yilgarn Craton. Although tectonic models for each are controversial, there are clear differences between the two cratons in terms of age, relative abundance of rock types and structure. There are also contrasting ranges of mineral deposits. The Yilgarn Craton is the more prospective, especially for nickel, gold and tantalum. It contains world-class deposits of each of these commodities and many other small to medium-sized deposits of nickel and gold. A vigorous approach to exploration in the Yilgarn Craton over the past fifteen years has been rewarded with a steady stream of discoveries and conversion of prospects to mines. The Archaean rocks of the Yilgarn have also given rise to large deposits of bauxite and heavy-mineral sands, as a result of Tertiary weathering processes. The Pilbara Craton appears to be less well-endowed with mineral wealth, but contains some large sub-economic deposits of platinum-group elements, molybdenum and barite, as well as several clusters of volcanogenic base-metal sulphide deposits. Some of these deposits may become operating mines in the medium term and indicate the potential for more, possibly higher grade deposits in the Pilbara Craton.

AUSGeoid98 v.1.0 data files:  (se49-10)

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.
