GEOLOGY

Detailed explanation-1: -Liquefaction takes place when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking. Liquefaction occurring beneath buildings and other structures can cause major damage during earthquakes.

Detailed explanation-2: -Soil Liquefaction Due to Earthquakes Earthquake motion can turn loosely packed, water-saturated soil to liquid-"liquefaction.” Liquefied soil loses its density and ultimately the ability to support roads, buried pipes, and, of course, houses.

Detailed explanation-3: -soil liquefaction, also called earthquake liquefaction, ground failure or loss of strength that causes otherwise solid soil to behave temporarily as a viscous liquid.

Detailed explanation-4: -Liquefaction occurs when an earthquake’s violent shaking suddenly turns loose, soft soil into liquid mud. As the ground gives way, buildings sink and pull apart. Sometimes, buildings weakened by an earthquake collapse during an aftershock.

Detailed explanation-5: -Liquefaction is the destabilization of sand or soil when groundwater (water underground) is forced out from between grains during the shaking of a moderate or strong earthquake. If liquefaction occurs under a building, it may start to lean, tip over, or sink several feet.
