%T ANALISIS POTENSI LIKUIFAKSI BERDASARKAN METODE GLOBAL GEOSPATIAL LIQUEFACTION MODEL DI KABUPATEN PACITAN
%X This research is motivated by the danger of liquefaction phenomena in Pacitan Regency caused by earthquakes. This study aims to analyze the liquefaction potential in Pacitan Regency based on the Global Geospatial Liquefaction Model (GGLM) method. The GGLM method utilizes three main parameters, namely the speed of shear waves at a depth of 30 meters (Vs30), the acceleration of soil vibration (PGA) and the soil wetness index or Compound Topographic Index (CTI). The Vs30 parameters used data obtained from the USGS, PGA obtained from the PUSKIM site and CTI parameters obtained from the Centre for Ecology and Hydrology's (CEH) website. The results showed that the Vs30 value ranged from 350 m/s to 900 m/s, the PGA parameter value ranged from 0.44 g to 0.51 g and the CTI parameter value ranged from 3 to 18. The potential for liquefaction occurred throughout Pacitan Regency with a probability value of > 0.99 and the distribution of settlements prone to liquidation was highest in the south of the study area.
