This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to improve models of future seismic hazard in Australia and globally. This will lead to improved predictions of future earthquake impacts in urban and natural environments and development of new paleoseismic techniques.

该项目旨在通过利用地质、地质年代学、地理空间、地震学、统计和数值模拟数据建立数百万年的地震记录，调查澳大利亚板内地震的行为和起源。它将利用板内地震的最大可信震级、最大震动强度以及史前大地震和当代大地震之间的时空关系来改进澳大利亚和全球未来地震风险的模型。这将改善对未来地震对城市和自然环境影响的预测，并开发新的古地震技术。
