Proposed

This project aims to assess the tsunami risk to Australia from volcanic sources in the south-west region by developing a database of realistic tsunami scenarios. This research addresses a current gap in tsunami risk knowledge, which has largely focused on earthquakes.

Project details

This project concept was submitted by the Queensland Fire Department.

The project will build on existing research from GNS Science, New Zealand and the Earthquake Research Institute at the University of Tokyo, Japan to model volcanic tsunami sources, estimate their likelihood, simulate inundation, and determine arrival times along the Australian coast. It will be guided by ATAG to ensure national consistency and alignment with strategic priorities. The work will be delivered in phases, starting with scenario development and risk ranking, followed by detailed inundation modelling.


This research will fill a critical blind spot in Australia’s tsunami preparedness by incorporating volcanic sources into national risk assessments and warning systems. It will enhance the accuracy and reach of tsunami warnings, support emergency planning at all levels of government and improve hazard awareness across the region.
