Tsunami Inundation Model Benchmark for the 2004 Indian Ocean Event

A 2004 Indian Ocean tsunami benchmark dataset from Geoscience Australia, last updated in 2026. It is proposed for validating all three stages of tsunami evolution—generation, propagation, and inundation. The data incorporates geodetic measurements, satellite altimetry, eyewitness accounts, and a detailed inundation survey of Patong Bay, Thailand.

Use Cases

• Validating tsunami source models based on geodetic earthquake measurements.
• Testing open ocean wave propagation models using satellite altimetry data.
• Assessing near-shore propagation and inundation extent with survey and eyewitness data.
• Conducting sensitivity analysis for model parameters like friction and wave height.

Strengths

• Benchmark validates all three stages of tsunami evolution: generation, propagation, and inundation.
• Utilizes multiple observational data sources, including satellite altimetry and a detailed field 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.
• Data freshness should be verified despite the 2026 update timestamp.
