Tsunami Inundation Model Benchmark for the 2004 Indian Ocean Event

Geoscience Australia Data provides a benchmark for validating tsunami models based on the 2004 Indian Ocean tsunami. The benchmark validates all three stages of tsunami evolution—generation, propagation, and inundation—using geodetic, satellite altimetry, eyewitness, and survey data. It was last updated on 2026-04-30.

Use Cases

• Validating tsunami source models based on geodetic measurements of the Sumatra–Andaman earthquake.
• Testing open ocean tsunami propagation models based on satellite altimetry data from the Jason satellite.
• Assessing near-shore wave propagation and run-up based on eyewitness accounts.
• Comparing simulated and observed inundation extents based on a detailed survey of Patong Bay, Thailand.
• Performing sensitivity analysis of inundation models to parameters like friction and boundary conditions.

Strengths

• Benchmark validates all three stages of tsunami evolution: generation, propagation, and inundation.
• Utilizes multiple observational data sources: geodetic, satellite altimetry, eyewitness accounts, and a detailed inundation survey.
• Includes sensitivity analysis on model parameters like friction and wave height.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
