Abstract Over 169 people along the Simangulampe upstream were under devastating flood and worst landslide watches in December 2023 due to a significant storm bringing heaviest rainfall moving giant boulders. Indeed, there are far fewer studies information on susceptibility hazards Simangalumpe than others. First-rate impressive risk mitigation strategies increased climate-change consideration reduced risk. We adopt C-band synthetic aperture radar multispectral imagery from Sentinel identify, visualize, analyze flash mapping mitigating address this issue. Precisely, is considered surface water indices with various parameters: Normalized Difference Vegetation Index (NDVI), Water (NDWI), Modified NDWI (MNDWI), SAR inundation mapping. Results show low NDVI values- over 50 percent of plant canopies damaged (uprooted broken trees) upstream. Combining properties index shows extent bodies Simagalumpe covers Finally, developing spatial temporal analysis data results flooding reducing unnecessary threats.
