Tsunami Hazard and Risk Assessment for New South Wales, Australia

Geoscience Australia Data produced a paper exploring tsunami risk to coastal communities in New South Wales. The work outlines results from risk scoping, examines tsunami sources and history, and includes inundation studies for selected sites. The paper also discusses how the results informed tsunami warning thresholds for NSW, with a last update recorded on 2026-04-30.

Use Cases

• Informing tsunami emergency planning and management based on the described risk scoping results.
• Assessing potential land inundation for low-lying populated communities based on the described modelling of earthquake-generated events.
• Confirming tsunami warning thresholds for NSW based on the described collaborative research with the Australian Bureau of Meteorology.
• Prioritizing risk reduction efforts for estuary foreshores and open coast sites based on the described hazard levels and return periods.

Strengths

• Paper is sourced from Geoscience Australia Data, a national geoscience agency.
• Analysis includes results from inundation studies for selected sites, as mentioned in the description.
• Work directly informed collaborative emergency management arrangements and warning thresholds.

Limitations

• The dataset is described as an HTML paper, not a structured data file; column-level documentation is absent.
• Row count and specific data formats for underlying models are unknown, which may limit suitability assessment.
• Freshness should be verified as the last update is a future date (2026-04-30).
