The eruption of Mount Anak Krakatau occurred on December 22, 2018, in the Sunda Straits, Indonesia, causing a tsunami that affected the coastal area of Banten Province. We use COMCOT 1.7 to make a tsunami model based on flank collapse caused by a landslide tsunami. The aim of study is to remodel past events to anticipate the mechanism and impact of the damage in the future. Bathymetry and topography are integrated to become high resolution data with a grid area of 49.8 meterss. The flank collapse scenario is applied with slide dimensions of 2000 meters long, 1500 meters wide, and 228 meters thick following previous study. The tsunami model consists of the initial tide model and the coastal model. The highest tsunami run-up of the tide model is in Carita of 1.9 meters height. The fastest arrival time of the tide model is in Sumur of 19 minutes. which is slightly different from previous studies due to different modeling applications and different initial tide locations. The highest tsunami run-up of the coastal model is in Lesung and Sumur of 2.5 meters height which almost matches the results of field observations.
