摘要：The seismic activities of a long section of the Sunda Plate revealed the vulnerability of the Indian Ocean to tsunami along the west coast of Sumatra, including on the west coast of Aceh Province. This megathrust caused the great tsunamigenic earthquake of 2004 and can be a possible candidate for rupture in the future and will affect or destroy everything, especially buildings along the coast. The west coast of Aceh Besar is one of the worst areas hit by tsunami waves and can cause tsunamis in the future. The objectives of this study are to determine the height, distance, and area of the tsunami inundation on the west coast of Aceh Besar District based on three earthquake magnitudes scenarios Mw 8.0, 8.5, and 9.2. The COMCOT (Cornell Multigrid Coupled Tsunami Model) tsunami model was used to obtain the height, area, and distance of the tsunami inundation. It was found that the largest tsunami inundation was caused by the tsunami generated by the magnitude Mw 9.2 earthquake. The maximum tsunami run up reached up to 20 meters with an inundation distance of 6 km from the coastline and a tsunami inundation area of 40 km2 distributed along the west coast of Aceh Besar District.
