Earthquake hazard model with AVS30 in Sukabumi, West Java Province

Abstract

The potential surface shocks due to the earthquake in Sukabumi is quite high. The purpose of this study is to provide an overview of the potential distribution of earthquake hazards on the earth’s surface. The methodology used for the potential earthquake hazard is the Peak Ground Acceleration (PGA) approach which is corrected by AVS30 analysis. The final results of the study can provide an overview of the potential of earthquake surface shocks grouped into three categories, namely low, medium, and high hazards. The variables used in this study were four types, namely: subsurface earthquake potential, slope shape, slope texture, and slope gradient. The study results of the potential for earthquake shocks can provide information on the potential hazards of earthquakes on the largest land surface in the Sukabumi City area and around the Cimandiri fault.
