This study aims to find possible active faults by analysing the morphotectonic features of the Cikandang Watershed in West Java, Indonesia. Morphometric indices including drainage density (Dd), lineament density (Ld), and bifurcation ratio (Rb) were computed using digital elevation models, topographic maps, and geological maps using Geographic Information System (GIS) software. As demonstrated by the different drainage patterns and lineament alignments that show tectonic activity, the analysis shows that tectonic forces substantially impact the watershed's shape. Higher Rb levels in sub-drainages suggest tectonic activity, while elevated Dd and Ld values indicate areas that are more susceptible to tectonic movements. These indices show possible active fault zones and strongly correlate with those shown on regional geological maps, especially in the watershed's centre and northern regions. In line with earlier studies that connected geomorphic indices to tectonic activity, the findings support the importance of these indicators in identifying active faults. This study highlights the importance of comprehensive morphotectonic assessments in determining earthquake hazards, providing vital information for disaster risk management and spatial planning in tectonically active areas. Through the alignment of geomorphic indices with geological features, the study pinpoint’s fault zones that need continuous observation, promoting safer community development and more resilient infrastructure in West Java's earthquake-prone areas.
