One Hundred Years of Earthquake Recording in Australia

Recurrence rates of large explosive volcanic eruptions

“…They found that recording bias is dependent on both eruption size, since larger events are more likely to be recorded than smaller events, and on timing, as events that happened a long time ago are less likely to be known about today than more recent eruptions. This finding is consistent with work in other fields; for example, it is well known that the completeness of the seismic record decreases as one goes back in time, with larger magnitude earthquakes more likely to be recorded than smaller earthquakes [e.g., Tinti and Mulargia, 1985;Albarello et al, 2001;Woessner and Wiemer, 2005;Leonard, 2008;Grünthal et al, 2009;Wang et al, 2009].…”

“…This phenomenon is not limited to volcanism; it is a well known problem in fields such as seismology [e.g., Tinti and Mulargia, 1985;Albarello et al, 2001;Woessner and Wiemer, 2005;Leonard, 2008;Grünthal et al, 2009;Wang et al, 2009]. The problem is made more complex because data biases also depends on magnitude with larger eruptions being more likely to recorded than small eruptions at any given age.…”

Impacts of Neogene-Recent compressional deformation and uplift on hydrocarbon prospectivity of the passive southern Australian margin

“…Inferred position of early Miocene (~15 Ma) shoreline modified after Veevers (2000). Earthquake epicentres were obtained from Geoscience Australia's earthquake database (Leonard 2008). The earthquakes shown occurred between 1900-2007 and represent a subset of the catalogue that has been filtered to meet national completeness levels and screened to remove aftershocks.…”

Thermal weakening localizes intraplate deformation along the southern Australian continental margin

“…173 that much of Australia's ongoing seismicity might be episodic rather than temporally and 216 spatially stationary, as advocated by Leonard (2008). However, Gutenberg-Richter relations 217…”
