利用有限差分法，论证了天皇海山对海啸波散射对2006年千岛群岛地震海啸传播的影响。模型的结果表明，天皇海山的贡献最大海啸能量沿着日本太平洋沿岸被发现高达50%以上。此外，对日本观测到的海啸记录的频谱演变分析表明，天皇海山的散射波可能在4至17分钟的周期内占主导地位。
The effect of tsunami wave scattering by the Emperor seamounts on the propagation of the 2006 Kuril Island earthquake tsunami is demonstrated, using the finite difference method. The model results indicate that the contribution of the Emperor seamounts on the maximum tsunami energy along the Pacific coast of Japan is found to be as much as 50% or more. Also, analysis of the spectral evolution of observed tsunami records in Japan suggests that the scattering waves from the Emperor seamounts possibly dominate the wave components at periods of 4 to 17 minutes.
