Pandeglang District becomes a concern because one of the locations had an impact on the Tsunami on December 22, 2018. Its position in the western waters and directly facing the Anak Krakatau Volcano is very potentially vulnerable. The Tsunami triggered by the volcanic activity of Anak Krakatau Volcano, mountain avalanche material. Evaluation regarding coastal land affected is also needed to anticipate future disasters. The study of the coastal areas affected by extraordinary events, such as the Tsunami, was carried out by stakeholders in evaluating coastal land to be more responsive to disasters. Three sub-districts with different morphology selected as samples of the affected areas, Labuan, Sumur, and Panimbang. We used highresolution Sentinel 2.0 images and Elevation Model Data (SRTM DEM) with unsupervised classification method to perform analysis of the area affected by Tsunami condition on coastal features. The results showed that the area affected especially the low land, as open land area at Labuan Sub-district was 189,298 Ha, Sumur Sub-district, 144,837 Ha, and Panimbang Sub-district was 282.852 Ha. Varied inundation range 50 - 200 meters from the coastline. The elevation of the three sub-districts shows vulnerable areas with an elevation of <2.5 m to 0.5 m above sea level.
