A benchmark for validating tsunami inundation models based on the 2004 Indian Ocean tsunami. The benchmark uses geodetic earthquake measurements, satellite altimetry data, eyewitness accounts, and a detailed inundation survey of Patong Bay, Thailand. It validates all three stages of tsunami evolution—generation, propagation, and inundation—and is used to test the hydrodynamic modeling tool ANUGA.
Use Cases
- Validate tsunami source models based on geodetic measurements of the Sumatra-Andaman earthquake.
- Test open ocean tsunami propagation models using satellite altimetry data from the Jason satellite.
- Assess near-shore propagation and inundation extent using eyewitness accounts and detailed field surveys.
- Perform sensitivity analysis on model parameters like friction and wave height perturbations.
- Incorporate building and structure data into computational meshes to study their influence on inundation.
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 field survey.
- Includes sensitivity analysis showing model predictions are comparatively insensitive to large changes in friction.
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.
- Row count is unknown, which may limit suitability assessment.
