ANALISIS KERAWANAN GEMPA BUMI MENGGUNAKAN STRUKTUR GEOLOGI DAN MIKROZONASI SEISMIK DI KABUPATEN OGAN KOMERING ULU, SUMATERA SELATAN

---

This study aims to analyze the level of earthquake susceptibility in Ogan Komering Ulu (OKU) Regency through the integration of geological structure parameters and seismic microzonation. Indonesia is a region with a high level of earthquake hazard due to its location at the convergence of several active tectonic plates. Although OKU is not directly located along a major fault line, the area still has potential seismic hazards due to the presence of local active faults and diverse geological conditions. The methods used in this study include analysis of distance to active faults, Fault Fracture Density (FFD), Peak Ground Acceleration (PGA), Average Shear Wave Velocity (AVS30), and Ground Amplification Factor (GAF). Parameter weighting was carried out using the Analytical Hierarchy Process (AHP), and then integrated through a weighted overlay method to produce an earthquake susceptibility zonation map. The results indicate that the OKU region generally falls within low to moderate hazard classes. Areas with high PGA values and low AVS30, particularly in young alluvial deposits and unconsolidated sediments, have a greater potential for ground motion amplification. Geological structure analysis reveals deformation patterns trending NE–SW and NW–SE, influenced by regional compression in southern Sumatra and potentially subject to reactivation. The final map classifies the OKU region into low, moderate, and high earthquake susceptibility zones.
