Abstract : One of the Indonesian provinces most vulnerable to flooding catastrophes is West Sumatra. West Sumatra is a province that spans 98°36' to 101°53' East Longitude and 00°54' North Latitude to 03°30' South Latitude. Its total size is roughly 42,297.30 km2, or 4,229,730 hectares, and it is surrounded by around 391 major and small islands. Flash floods and landslides have affected a number of regencies and cities in West Sumatra, including Agam Regency, Tanah Datar Regency, Padang Panjang City, Padang Pariaman Regency, and Padang City. The objective of this study is to use vegetation index estimates based on Landsat-8 satellite images to categorise flood catastrophe risk zones in West Sumatra. NDVI = -0.106 and NDWI = -0.03999, respectively, are examples of vegetation indices that define land as either non-vegetated or sparsely vegetated, and SAVI = 0.0002447 classify areas with water bodies such as rivers/floods.

Keywords : Disaster Mitigation, Remote Sensing, NDVI, NDWI, SAVI.
