2004 Indian Ocean Tsunami Model Validation Benchmark with Multi-Stage Data

A new benchmark for tsunami model validation is proposed 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. Geoscience Australia Data published this scientific journal paper, which also validates the ANUGA hydrodynamic modeling tool.

Use Cases

• Validating tsunami source models based on geodetic measurements of the Sumatra-Andaman earthquake.
• Testing open ocean tsunami propagation models based on Jason satellite altimetry data.
• Assessing near-shore wave propagation 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 wave height.

Strengths

• Benchmark validates all three stages of tsunami evolution: generation, propagation, and inundation.
• Utilizes multiple observational data sources: geodetic, satellite altimetry, eyewitness, and a detailed inundation survey.
• Includes sensitivity analysis showing model predictions are comparatively insensitive to large changes in friction.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific 2004 event and survey locations.
