Tsunami Inundation Model Benchmark Using 2004 Indian Ocean Event

A benchmark for tsunami model validation based on the 2004 Indian Ocean tsunami. The dataset incorporates geodetic earthquake measurements, satellite altimetry, eyewitness accounts, and a detailed inundation survey of Patong Bay, Thailand. It validates all three stages of tsunami evolution: generation, propagation, and inundation.

Use Cases

• Validate tsunami source models using geodetic measurements of the Sumatra-Andaman earthquake.
• Test open ocean propagation models with Jason satellite altimetry data.
• Assess near shore propagation using eyewitness account data.
• Compare simulated and observed inundation extent with the detailed Patong Bay survey data.
• Conduct sensitivity analysis on model predictions for factors like friction and wave weight at the 100 m depth contour.

Strengths

• Benchmark validates all three stages of tsunami evolution: generation, propagation, and inundation.
• Utilizes a uniquely large amount of observational data from the 2004 Indian Ocean tsunami.
• Incorporates real-world structures like important buildings into the computational mesh for accuracy.

Limitations

• Specific data volume, row count, and column structure are unknown.
• Primary data is embedded within a scientific paper (HTML format), requiring extraction for direct analysis.
• Geographic focus is specific to the 2004 Indian Ocean event and Patong Bay, Thailand.
