Short summary
We demonstrate a method of tsunami risk assessment for two buildings using copulas of tsunami hazards that can consider the nonlinear spatial correlation of wave heights. As a result, the maximum value of the expected aggregate damage probability was approximately 3.0 % higher in the case considering the wave height correlation. We clearly showed the importance of considering wave height correlation and the usefulness of copula modeling in evaluating the tsunami risk of a building portfolio.
