Which mechanism causes increased soil liquefaction following land reclamation using alluvial deposits rich in silt?

💡 Explanation

When reclaimed land with saturated alluvial silt experiences seismic activity, the lack of cohesion causes reduced intergranular friction because the pore water pressure increases, decreasing effective stress. Therefore liquefaction occurs, rather than oxidation, cementation, or increased stress, which require stable or unsaturated conditions.
