澳大利亚的概率地震风险分析基本上依赖于这样一种假设，即过去记录的地震预示着未来将在哪里发生地震。尚未尝试评估来自活动断裂源的数据可能对建模过程作出的潜在贡献，尽管近年来已成功地将此类数据纳入美国和新西兰的危险地图。本文回顾了澳大利亚有限的古地震学研究历史，并讨论了活动断裂源数据对提高我们对板内地震活动的认识的潜在贡献。评估了澳大利亚活动断裂源数据纳入未来概率危险模型的可用性和适宜性，并提出了实现这一目标的适当方法。
Probabilistic seismic hazard analyses in Australia rely fundamentally on the assumption that earthquakes recorded in the past are indicative of where earthquakes will occur in the future. No attempt has yet been made to assess the potential contribution that data from active fault sources might make to the modelling process, despite successful incorporation of such data into United States and New Zealand hazard maps in recent years. In this paper we review the limited history of paleoseismological investigation in Australia and discuss the potential contribution of active fault source data towards improving our understanding of intraplate seismicity. The availability and suitability of Australian active fault source data for incorporation into future probabilistic hazard models is assessed, and appropriate methodologies for achieving this proposed.
