Lombok Island, West Nusa Tenggara Province, has relatively high earthquake activities where it is influenced by the existence of a subduction zone or Megathrust in the southern part and Back Arc Thrust in the northern Lombok. The high earthquake activity indicates that the potential of tsunami events in Lombok is also relatively high, especially due to the earthquake in Megathrust. Hence, this study aims to provide an overview of the maximum tsunami inundation in the Kuta Mandalika area, and is expected to be as an additional reference in determining evacuation routes and gathering points (tsunami shelters). Based on the results of the maximum tsunami inundation, then a map was prepared that describes the evacuation route in Mandalika, Central Lombok Regency against the danger of a tsunami. For this purpose, computational analysis is carried out through Community Model Interface for Tsunami (ComMIT) using the Method of Splitting Tsunami (MOST) made by the National Oceanic and Athmospheric Administration (NOAA) Center for Tsunami Research. The modeling results show that the highest and largest inundation was caused by the Megathrust earthquake source in the Bali segment with a magnitude of 9.0. While the flow depth shows that the maximum inundation that occurs in Kuta Mandalika is around 0.5 to 12 meters on the shoreline with an inundation area of 15.27 km2. Furthermore, this flow depth can be used as a basic reference in preparing a tsunami evacuation map.
