Description: Liquefaction is a process where loose, wet sediments lose strength during an earthquake and behave similarly to a liquid. Once a soil liquefies, it will tend to settle vertically and/or spread laterally. With even very slight slopes, liquefied soils tend to move sideways downhill (lteral spreading). Settling or lateral spreading can cause major damage to buildings and to buried infrastructure such as pipes and cables.
