The study of liquefaction potential of a place is of utmost importance  regarding the safety of both life andproperty. Liquefaction of soil followed by earthquakes has always been a source of danger for the people living in the highly vulnerable seismic zones of the  world. Guwahati which is attributed  under Zone V, the highest seismic zone level as per Indian Standard  code  of practice (IS 1893) is highly vulnerable to earthquakes, therein lies the  hidden danger of liquefaction just after an earthquake. In this paper the various liquefaction potential studies of Guwahati city, which has been carried out is reviewed considering the significant role liquefaction has played in the past earthquakes and rising danger with increase in population. Besides this, the difference in their conclusions is shown and necessary approaches still required were discussed
