Detailed explanation-1: -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-2: -Liquefaction – A temporary state in which loose soil and rock materials take on the property of liquid, often as a result of severe ground-shaking. Magnitude – The measure of the amount of energy released in an earthquake.
Detailed explanation-3: -Examples of soil liquefaction include quicksand, quick clay, turbidity currents and earthquake-induced liquefaction. Depending on the initial void ratio, the soil material can respond to loading either strain-softening or strain-hardening.
Detailed explanation-4: -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.
