Abstract: Fundamental response of sandy soil to seismic forces turnout as a mainstream issue, which depends upon numerous factors. Failure of earth under foundation specifically loose saturated sand, due to the phenomenon called liquefaction, has been responsible for tremendous loss of property and life in the past, all over the world. That is why; geotechnical engineers are trying their best to explore the conditions favouring this phenomena and methods to tackle this problem. As the frequency of severe earthquakes manifolds in recent years, a thorough study and understanding of liquefaction is the need of the time, in order to minimize the losses. This paper reviews the phenomenon of liquefaction and various protective measures to avoid circumstances advocating liquefaction. This focus underlines structural engineering measures like spread foundation, revetments, as well as nonstructural engineering methods like soil solidification and replacement methods, lowering water table by various measures, confining the soil, dissipation of pore water pressure, and shear strain restraint method. This research draws upon mostly primary sources includes published letters, and a complete collection of little reviews. This review published techniques put forward by The Japanese Geotechnical Society after extensive liquefaction failure during 1964’s earthquake and lesson learnt at Kobe during 1995 Hyogo-Ken-Nanbu earthquake.
