<![CDATA[Kapanewon Pundong is in an active tectonic zone and has experienced significant seismic events, including the 2006 Bantul earthquake (Mw 6.3), which caused extensive damage. Liquefaction was a key contributor to infrastructure failure during the event. This study aims to evaluate liquefaction potential in Kapanewon Pundong through integrated microtremor and geospatial analysis. The Horizontal-to-Vertical Spectral Ratio (HVSR) method assessed local site effects that influence ground shaking. Liquefaction probability was estimated using the model by Zhu et al. (2017), considering parameters such as Vₛ₃₀, PGV, water table depth (WTD), distance to water bodies (DW), and average annual precipitation. The research findings include Vₛ₃₀ values that range from 221 to 893 m/s, PGV values from 16 to 29 cm/s. Panjangrejo and Srihardono villages exhibit the highest liquefaction probabilities, up to 30%. The estimated Liquefaction Spatial Extent (LSE) in these areas reaches 5.1%. These findings identify high-risk zones for earthquake-induced liquefaction and provide a quantitative foundation for spatial planning and disaster mitigation strategies in the region.]]>
