Presenter: Dr Dan Clark, Geoscience Australia
Long-term patterns in large earthquake occurrence, both temporal and spatial, can be deduced from the Australian landscape record and used to inform contemporary earthquake hazard science. Seismicity source parameters such as fault slip-rates, large earthquake recurrence and magnitude vary across the continent, and can be interpreted within a framework of large-scale neotectonic domains defined on the basis of geology and crustal setting.
Recurrent large earthquakes also have the potential to effect dramatic landscape change, and profoundly influence the distribution and thickness of regolith materials. This has potential implications for groundwater systems, and in some cases mineral exploration and production.
Dr Dan Clark gained his PhD in supercontinent reconstruction in 1999 from the University of NSW. He then worked for two years as an Engineering Geologist before joining Geoscience Australia in 2001. Since then he has focused on the development of seismo-tectonic models describing large earthquake occurrence in intraplate regions.
