The Potential Tsunami Impact to Coastal Vegetation and Geological Landscape in Segari, Lumut

One of the strongest ever seaquake measured on the 26th of December, 2004 caused a highly catastrophic tsunami event taking over more than 300,000 lives. This was mainly caused by the rupture of a 1200km fault line from the coast of Sumatra raising the seafloor to over 8 meters in height, thus raising the water level (known as tsunami) that was travelling at a speed of nearly 800 km/h. Tsunami is a large wave produced due to the sudden displacement in sea floor where it most commonly occurs at the subduction zone. At shallower earthquake depth, a greater tsunami is generated as compared to deeper depths. In this study, a fieldwork was carried out in order to observe the presence of coastal vegetation, geological landscape and also determining potential escape route. All these were done to study the potential impact tsunami might have on the study area. TUNA software was used to perform simulation at the Malacca Straits with reference to the source that is located at Andaman, Indonesia. Linear Shallow Water Equation was used in order to illustrate tsunami propagation. The findings of this study will then represent the tsunami wave run-up and inundation following the simulations that were done.
