The Manila Trench subduction zone is an active convergent plate margin between the South China Sea and northern Philippines. This strongly indicates a high probability for larger earthquakes that could potentially trigger a tsunami in the future and anticipated to affect neighboring countries such as Malaysia which has power plants near the coastal areas. The potential disastrous impact of tsunami waves on a power plant causes loss of lives, damage to assets, and loss of electricity for the coastal communities similar to year 2011 Tohoku tsunami in Japan. Therefore, application of shallow water equation (SWE) in tsunami modelling namely generation and propagation phase and nonlinear shallow water equation (NSWE) for run-up and inundation phase of a tsunami event are pertinent in simulating various scenarios of tsunami. Results from tsunami simulation is used as tsunami lateral load. Linear Static Analysis is then utilized to analyze stability of 275-kV transmission tower.

马尼拉海沟俯冲带是位于南海和菲律宾北部之间的活动板块边缘。这强烈表明发生更大地震的可能性很高，可能在未来引发海啸，并预计会影响邻国，例如在沿海地区拥有发电厂的马来西亚。与 2011 年日本东北海啸类似，海啸波对发电厂的潜在灾难性影响会导致沿海社区的生命损失、资产损坏和电力中断。因此，浅水方程 (SWE) 在海啸建模中的应用，即海啸事件的产生和传播阶段以及非线性浅水方程 (NSWE) 用于模拟海啸的各种情景是相关的。海啸模拟的结果用作海啸横向载荷。然后利用线性静态分析来分析 275 kV 输电塔的稳定性。
