A sea wave produced by the displacement of the sea floor.

A phenomenon sometimes associated with earthquakes, in which soils and other unconsolidated materials saturated with water, behave as a liquid.

|
|
The fact that liquid exists.

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: -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.
Detailed explanation-4: -Liquefaction occurs in water-saturated unconsolidated soils affected by secondary seismic waves (S-waves) which cause ground vibrations during earthquakes.
