What is liquafacation?

Answer 1

Liquefaction is a geological process that occurs when saturated soil loses its strength and stiffness due to applied stress, typically during events like earthquakes. This results in the soil behaving more like a liquid, which can cause buildings and structures to sink or topple. The phenomenon is most common in loose, water-saturated sediments, where the increased pore water pressure reduces the soil's ability to support weight. As a consequence, areas prone to liquefaction can experience significant damage during seismic events.
