Probabilistic Tsunami Inundation Hazard for New South Wales, Australia

New South Wales, Australia, is the geographic scope for this probabilistic tsunami hazard assessment (PTHA) dataset. The data models tsunami inundation hazard uniformly at about 30-meter resolution over the entire coast, spanning more than 1000 kilometers. It was produced by Geoscience Australia using three Monte Carlo samples of 360 scenarios each from the 2018 Australian PTHA.

Use Cases

• Designing tsunami evacuation zones based on probabilistic inundation hazard maps.
• Assessing the risk to coastal infrastructure from earthquake-generated tsunamis.
• Comparing the effectiveness of multiple importance sampling techniques for large-scale hazard modeling.
• Informing the placement and design of vertical evacuation structures using spatially extensive hazard data.

Strengths

• Models inundation hazard uniformly at about 30-meter resolution over the entire coast of New South Wales.
• Employs a rigorous multiple importance sampling method using three Monte Carlo samples of 360 scenarios each.
• Covers a spatially extensive area spanning more than 1000 kilometers (over 10 degrees latitude).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
