Re-evaluating the seismic hazard potential of the northern Lapstone Structural Complex
Based upon a structural model for the LSC involving a large west-dipping thrust fault beneath the Lapstone Monocline, a recent study of seismic hazard in the Sydney Basin identified the LSC as a potential source for large and damaging earthquakes, and estimated a recurrence for MW >7.0 events at 15-30 ka (IGNS, 1999). The preliminary results presented here from Mountain Lagoon, a small lake abutting the Kurrajong Fault, indicate that only 15m of fault displacement has occurred since the catchments upstream became too dissected to generate significant fluvial flow. A qualitative assessment of the time required to reconstruct the catchment to a size where a sandstone fault barrier could be eroded suggests that the observed displacement is all that has occurred in the last several million years or more. This indicates potential recurrence rates for large earthquakes are, on average, in the order of hundreds of thousands of years or more.
