大洋脊可以充当波导，将海啸能量传输到数千公里之外，将大量能量作为辅助来源泵入远场区域。浅水波速c=(gh)1/2只能准确预测早期信号的到达时间，而很难估计脊陷波的到达时间。本研究提供了一种快速分析预测方法来估计后续大陷波的到达时间。该方法基于均匀抛物线形潜脊上陷波的能量速度解。选择位于 Sand Island 和 Nawiliwili 附近的 2011 年东北海啸的两次验潮站的记录来说明该方法的应用。沙岛记录显示了典型的公海岛屿特征，即最大波高后振幅快速衰减。虽然纳维利维利记录受到夏威夷山脊地形捕获效应的强烈影响，并且随后的几个波列...
Oceanic ridges could act as waveguides transferring tsunami energy to thousands of kilometers away, pumping large energy in to far-field regions as a secondary source. The shallow-water wave velocity c = (gh)1/2 can only predict the arrival time of the early signals accurately but can hardly estimate that of ridge-trapped waves. The present study provides a fast analytic prediction method to estimate the arrival time of the subsequent large trapped waves. The method is based on the energy velocity solution of trapped waves over the uniform parabolic-shaped submerged ridge. Records of two-tide gauge stations, located nearby Sand Island and Nawiliwili for the 2011 Tohoku tsunami are chosen to illustrate the application of this method. The Sand Island record shows typical open-ocean island characteristics that the maximum wave height is followed by rapid amplitude decay. While the Nawiliwili record is strongly affected by topographical trapping effect of the Hawaii Ridge, and several subsequent wave trains c...
