The Sydney Basin encloses a significant proportion of the Australian population, and the 1989 M5.6 Newcastle earthquake demonstrated that the basin is not immune from the impact of even relatively modest earthquakes. In spite of this, few investigations have been conducted to identify and characterise potential geologic sources of strong ground shaking. A recent major study of the southern part of the basin commented that

The available data are less complete than ideal for the purposes of probabilistic seismic hazard analysis. Essentially, the extreme infrequency of large earthquake events in intraplate regions, such as Australia, means that the short historic record of seismicity is poorly suited to the task of assessing seismic hazard.

Hence, geologic, geomorphic and paleoseismic knowledge has a vital role to play in obtaining constraint on the probable location and recurrence of large and damaging earthquakes near Sydney. In April 2005 a one day workshop at the University of Sydney brought together a diverse range of researchers with experience in the geology and geomorphology of the Sydney Basin, neotectonics and seismic hazard science. A series of seminars were presented covering geology, geomorphology, seismicity and seismic hazard. These served as a nucleation point for subsequent discussion, and the drafting of the papers presented herein.
This proceedings volume contains within its covers tools for understanding large earthquake occurrence within the Sydney Basin and compiles 12 papers addressing landscape and structural developement, and seismic hazard aspects, of the Lapstone Structural Complex west of Sydney. Hence, it represents a framework upon which future advances in our understanding of the seismic hazard posed to Australia's largest population centre may be based.
