Summary:

This is a guest post by Szymon Świątek New research challenges the assumption that only strong earthquakes cause liquefaction. Scientists from Poland demonstrated that even low-magnitude shocks (~M3.5) can trigger sediment deformation in water-saturated fine-grained sediments. This finding expands our understanding of seismic activity and its effects on geological structures. The study revealed that sediment composition plays a crucial role in liquefaction susceptibility. Upper sandy layers, which are less compacted, were particularly prone to deformation under seismic stress. The experiments
