A new probabilistic tsunami hazard assessment for Australia

Dozens of tsunamis were recorded in Australia since 1900, the larger of which induced locally significant inundation and hazardous marine currents. Substantially more hazardous tsunami could be generated by large earthquakes in the south-west Pacific or eastern Sunda Arc.

To facilitate understanding of these risks, in 2008 Geoscience Australia developed an offshore probabilistic tsunami hazard assessment, which provides  earthquake-tsunami scenarios and return-periods for detailed inundation hazard mapping throughout Australia.

Recent advances in observation and uncertainty quantification have substantially improved our capacity to model tsunamis, leading Geoscience Australia to develop a new probabilistic tsunami hazard assessment for release in 2018.

Gareth Davies has worked for Geoscience Australia since 2010 on a range of natural hazards projects, particularly related to the computational and statistical modelling of tsunamis, floods, and coastal storm waves. He previously completed a PhD in coastal geomorphology at Wollongong University, and studied mathematics and geography at Melbourne University.

This talk is presented as part of the Wednesday Seminar Series.
