QLD Tsunami Inundation Modelling Report for Gladstone Region 2024-2025

Geoscience Australia developed a Probabilistic Tsunami Hazard Assessment (PTHA) for the Gladstone region from Agnes Waters to Yeppoon. The report details modelling validated against three historic tsunami events and provides conservative inundation zone estimates corresponding to Australian tsunami warning categories. It was published via the Australian Ocean Data Network in 2026.

Use Cases

• Develop targeted evacuation plans based on probabilistic inundation zone estimates.
• Validate tsunami hazard models using the three historic events referenced in the report.
• Assess marine hazard risks for coastal infrastructure based on earthquake scenario sampling.
• Inform emergency management policy using conservative estimates aligned with national warning categories.

Strengths

• Model validation against three historic tsunami events provides a basis for accuracy.
• Probabilistic sampling of earthquake scenarios from major Pacific subduction zones.
• Results are aligned with current Joint Australian Tsunami Warning Centre warning categories.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing solely on the Gladstone region.
