Probabilistic Tsunami Hazard Assessment for the Gladstone Region, 2024-2025

A Probabilistic Tsunami Hazard Assessment (PTHA) developed by Geoscience Australia in partnership with the Queensland Fire Department for the Gladstone region, from Agnes Waters to Yeppoon. The report details the modelling approach, validates it against three historic tsunami events, and provides probabilistic sampling of earthquake scenarios and their occurrence rates. Results include conservative estimates for possible inundation zones corresponding to current Joint Australian Tsunami Warning Centre warning categories.

Use Cases

• Develop targeted evacuation plans based on modelled inundation zones.
• Assess marine hazard risks for coastal infrastructure based on probabilistic earthquake scenarios.
• Validate tsunami hazard models using comparisons against three historic tsunami events.
• Inform emergency management strategies using conservative estimates linked to official warning categories.

Strengths

• Modelling validated against three historic tsunami events.
• Results provide conservative inundation estimates linked to official warning categories.
• Covers a specific coastal region from Agnes Waters to Yeppoon.

Limitations

• Data is presented in a PDF report format, limiting direct machine-readability.
• Column-level documentation and sample data are unavailable, requiring manual inspection.
• The underlying raw model data and its specific spatial/temporal resolution are not described.
