AMPLIFIC LIQUEFACTION INTRODUCTION Amplific liquefaction refers to a process during earthquakes where the strength and stiffness of saturated soil decrease drastically due to the amplification of seismic wave energy. This occurs when seismic waves cause pore water pressure in loose, water-saturated sediments to increase until the soil particles lose contact, leading to a temporary transformation of solid ground into a fluid-like state.
