Abstract
This study, unique in its focus on the Kepahiang Regency, Bengkulu Province, aims to analyse soil characteristics and their potential impact on infrastructure stability using shear wave velocity (Vs) data from 30 microtremor points spread across Kepahiang. The analysis produces a soil layer profile, shear wave velocity variations at various depths, Vs distribution maps, soil classifications, and ground amplification factors. The study reveals a significant risk of soil resilience effects in the area, primarily due to the dominance of class C soil, which consists of very dense soil and soft rock, and class D soil, which is rigid. The high amplification factor caused by the low average shear wave velocity to a depth of 30 m also affects soil resistance. This research contributes significantly to geotechnical risk mitigation efforts, safer spatial planning, and infrastructure development resistant to landslides in the Kepahiang Regency.
