Abstract
West Nusa Tenggara was ever hit by an earthquake and tsunami on August 19th, 1977. This earthquake and tsunami made an impact on the area of Kuta Village Central Lombok, which is under the Mandalika Tourism Area (MTA) development now. This research conducted the assessment of the MTA development impact on the Kuta Village based on the tsunami hazard analysis point of view. This research applies the bathymetric data, the before development topography, and the after development topography to make the simulation of tsunami waves run-up. The analysis of tsunami waves run-up used four-wave height scenarios, i.e. 3.5 meters of before development and 3.5 meters, 5 meters, 7 meters of after development. The result of the tsunami simulation showed differences. The tsunami inundation area in the MTA decreased by 855,617.12 m2. But, the tsunami inundation area in the Kuta Village was increased by 3,278 m2.
