In this study assessed the topography and geology of Padang city, Indonesia, to detect areas susceptible to liquefaction hazards. This was done by utilizing satellite imagery and in-situ data. Liquefaction is a phenomenon where saturated soil loses its bearing capacity during shaking. This can threaten densely populated areas. In this study, the main data used was Landsat 8 satellite imagery, which was analyzed using ENVI and ArcGIS software, to evaluate the hazard by extracting important topographic features, such as hillshade and slope. From these data, surface morphology and landforms that affect liquefaction potential were obtained. Then, in-situ sampling was carried out to determine the type of soil, which was used to improve the accuracy of the research results. Through the analysis of hillshade and slope attributes, areas characterized by lowland and flat topography, along with soft, unconsolidated soil types, can be determined as areas that are more susceptible to liquefaction. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2026.
