“…Liquefaction is more likely to occur on water-saturated, unconsolidated soils with low porosity, such as sandy loam, sand, and fine gravel. When an earthquake occurs, the unconsolidated sand layer tends to experience volume shrinkage (Lakkimsetti, 2023), (Chakrabortty, 2021). The process of shrinking soil volume during an earthquake in the form of dynamic loading will cause excess pore water pressure and reduce the value of soil shear strength (Karim ME, 2014), (Taiebat M, 2007).…”

Liquefaction Potential Index (LPI) is a technical standard for assessing an area that can become liquefied, representing the accumulation of damaged soil layers. This study used interpolation techniques to visualize the distribution of potential liquefaction in an area, which includes Topo to Raster, Spline, Inverse Distance Window, and Kriging. This interpolation technique compares the most effective methods for describing the LPI distribution. This study's results show that the Topo to Raster interpolation technique is assumed to be the most effective in explaining the LPI distribution by considering the correlation between LPI and amax for the Bantul area. In the validation test, the Topo to Raster correlation results produced the optimum R2 value (0.769) among the three other interpolation techniques, 0.476 (RMSE) and 0.911 (MAE). Pearson's test showed that the Topo to Raster produced a strong relationship between amax and LPI of 0.863. Visualization of the 2D LPI distribution is essential to mitigate the liquefaction so that this approach can minimize the potential damage to the foundation design and civil building structures.
