Abstract

Australia's rich neotectonic record provides an opportunity to better understand the characteristics of seismogenic intraplate deformation, both at the scale of a single 'active' fault and at the scale of the entire continent. Over the last decade knowledge of Australian intraplate faults has advanced significantly. Herein we review this knowledge and propose six preliminary seismicity source zones (domains) based upon neotectonic data. Each source zone contains 'active' faults that we contend share common recurrence and behavioural characteristics, in a similar way that source zones are defined using the historic record of seismicity. A seventh offshore domain is proposed based upon analogy with the eastern United States. The power of this domain approach lies in the ability to extrapolate characteristic behaviours from well characterised faults (few) to faults about which little is known (many), both nationally and to analogous regions elsewhere in the world. This data, and conceptual and numerical models describing the nature of the seismicity in each source zone, has the potential to significantly enhance our understanding of seismic hazard in Australia at a time scale more representative than the snapshot provided by the historic record of seismicity. This includes providing a means by which to estimate key parameters underpinning the next generation seismic hazard maps for Australia, such as maximum magnitude earthquake and seismic source zone b values.
