Which geological hazard is amplified when saturated sediment exists above faults?

💡 Explanation

Liquefaction-induced ground deformation is amplified because seismic shaking causes water-saturated, granular material to lose strength via the mechanism of increased pore water pressure. Therefore, ground shifts more than usual, rather than other geological effects, because material acts like a fluid.
