  • Seismic and navigation data for selected lines from seismic surveys T69A and T70A in SEGY format.

  • Seismic refraction investigations were made at five sites in the vicinity of Alice Springs, Northern Territory, by the Bureau of Mineral Resources in August 1962. This work was done, at the request of the Bureau of Mineral Resources Observatory Group, to select the most suitable site for a seismological observatory. In view of the desirable features for such a site - a bedrock having a high seismic velocity and a bedrock at shallow depth - a site about three miles west of Alice Springs is recommended as the most suitable; the bedrock material has a velocity of 17,800 ft/s and the thickness of overburden is less than 20 ft.

  • A reconnaissance seismic reflection and refraction survey in the East Otway Basin, Victoria, was carried out by the Bereau of Mineral Resources from mid-February to mid-June 1967. The objective of the survey was to determine whether the gravity low areas of the Torquay Embayment and Port Phillip Sub-Basin in the eastern part of the Otway Basin contain thick Cretaceous sediments like those which has shown potential hydrocarbon source and reservoir characteristics in the western part of the Otway Basin. Nine reflection and five refraction traverses were recorded in the gravity low areas of the Barwon Trough and Port Phillip Sub-basin. Single-coverage reflection results of variable quality were obtained. Evidence for the presence of Tertiary section is provided by shallow reflections of good to fair quality, but the evidence for Cretaceous sediments is tenuous because of the poor quality of the deeper reflections, some of which may be multiples. The presence of several faults, onlappings and pinch-outs is also indicated. The refraction results are considered unreliable because of the difficulty of interpreting the discontinuous profiles and because of the mapped and suspected faults and pinch-outs in the sections.

  • Mignan et al. (2015) estimated the maximum rupture lengths for strike-slip faults, by applying a multisegment rupture method, and calculated new Mmax values, by applying selected strike-slip scaling relations. In an initial step they compared the European fault length - Mmax data with five candidate relations and on the basis of this comparison dismissed two. In this paper the bilinear scaling relation of Leonard (2010, 2014) was incorrectly applied and so gave anomalously high estimates of magnitudes for fault lengths greater than 45km. As such it was excluded from future consideration. The problem likely arose due to the MW relations in Table 6 of Leonard (2010) being a subset of the full set of M0 relations given in Table 5. A more comprehensive set of MW relations is given in Leonard (2014). Table 1 below is the equivalent of Table 1 in Mignan et al. (2015), with all the relations reworked into the MW = a + b log(L) formulation to allow easier comparison.

  • The collection consists of field, processed and navigation seismic data plus acquisition processing and interpretation reports. The collection is derived from the marine seismic field programs undertaken by Geoscience Australia, Australian Geological Survey Organisation (AGSO) and Bureau of Mineral Resources (BMR) since the 1980s. Data used by petroleum industry for exploration, GA for frontier petroleum programs and academia for research. 80% of data requests from industry.
