Microzonation of Soil Resistance Based on Shear Wave Velocity Variation: Case Study of Kampung Melayu District, Bengkulu City
Abstract
This research presents a unique microzonation map based on shear wave variations, specifically Vs10, Vs20, Vs30, Vs40, and Vs50. Microzonation is dividing a region into smaller zones based on specific characteristics, such as soil resistance to seismic waves. The method used in this research includes secondary data collection of shear wave velocity values and soil layers in the District of Kampung Melayu, then producing shear wave velocity distribution at various depths, soil site class distribution map, and Ground Amplification Factor (GAF) distribution map. The results of this study indicate that the variation in shear wave velocity at different depths provides an overview of the soil type resistance in Kampung Melayu District, Bengkulu City. The resulting microzonation map, a novel approach in this context, indicates an increase in the Vs value with increasing depth. Additionally, the Ground Amplification Factor (GAF) distribution reveals that areas with low soilspecific resistance exhibit higher amplification values, thereby increasing their susceptibility to seismic vibrations. These findings provide valuable and novel information for earthquake risk mitigation and the planning of safer infrastructure in this area, significantly contributing to civil engineering and urban planning.
