Abstrak

This study aims to analyse subsurface geological conditions and seismic vulnerability levels using the microseismic method with 17 measurement points to obtain the Seismic Vulnerability Index (SVI) and shear wave velocity (Vs) parameters. The analysis results show a strong correlation between these two parameters in identifying weak subsurface zones that have the potential for earthquake wave amplification. High SVI values indicate significant vibration amplification potential. The Vs results reinforce these findings, with point 3 having the highest Vs value of 1,491.99 m/s (Hard Rock/SA), indicating dense and compact rock, while point 14 has the lowest Vs value (Soft Soil/SE), reflecting a soft layer with high amplification potential. The integration of SVI and Vs parameters confirms that point 14 is a critical zone with the highest seismic vulnerability, requiring special attention in disaster mitigation, spatial planning, and infrastructure development.
