Abstract

The Research of potential liquefaction analysis based on the geospatial model has been successfully conducted. This study aimed to determine the probability of liquefaction P [Liq] from the geospatial model based on 3 main parameters such as Peak Ground Acceleration (PGA), Velocity Shear at a depth of 30 meters (Vs30) and Compound Topographic Index (CTI). The Research data were obtained from microtremor field measurements and spatial data from the United States Geological Survey (USGS) site and the Center for Ecology and Hydrology (CEH). Microtremor data was measured by a Seismograph TDS 303S sensor at 48 measurement points with an interval of 1 Km between points. Microtremor measurement data obtained are then processed using the Horizontal to Vertical Spectral Ratio (HVSR) method to obtain the values of dominant frequency (f0) and Amplification (a0). The f0 value is used to calculate the PGA value while the Vs30 value is obtained from USGS spatial data and CTI value is obtained from CEH spatial data. Values from the PGA, Vs30 and CTI obtained were then calculated using the geospatial model approach to determine the probability of liquefaction. The results showed that the probability value of liquefaction between 0,10 to 1 where the value of 1 dominates in the study area. This condition showed that the most of area have the potential to be affected by liquefaction events.
