In a new study, the conventional understanding of soil liquefaction is being challenged, significantly reshaping our comprehension of earthquake-related soil deformation. Traditionally, soil liquefaction has been linked to undrained conditions near earthquake epicenters, but this research reveals that liquefaction can take place under drained conditions, even at considerably lower seismic-energy density levels. This discovery sheds new light on far-field liquefaction events that have long perplexed scientists. The study highlights how seismic shaking, even in drained conditions, triggers interstitial fluid flow within the soil, leading to the accumulation of excess pore pressure gradients and the subsequent loss of soil strength. Drained liquefaction unfolds rapidly, guided by the propagation of a compaction front, with its speed determined by the rate of seismic-energy injection. These findings mark a profound shift in our understanding of soil liquefaction, empowering us to conduct m
