Liquefaction and lateral spreading were common in the area affected by the magnitude 8.8 earthquake of Chile in 2010. In the town of Linares, located 88 km east of the epicenter, the soil liquefaction caused severe structural damage on buildings from a local industrial facility, differential settlements, rocking of a concrete silo, and important indirect losses. This study summarizes the observed ground failure consequences, the geotechnical characterization of local soils, and presents the analysis of a liquefaction potential. The studied facility consists of closely spaced concrete silos and metallic silos. The facility is located on flat alluvial deposits in the central valley, an area crossed by several creeks and estuaries, and 5 km south of a major river. The site investigation consisted on open shallow pits for visual and physical characterization, and deep borings where standard penetration tests were conducted to develop shear strength profiles. It was concluded that the liquefied layers correspond to shallow deposits of loose saturated sands and low plasticity, with average blow counts below 15. In addition to the low soil strengths, the ground motion duration and intensity were critical factors in the initiation of liquefaction and were found to correlate well with the extent of the observed damage.
