Large number of cases have been rep or ted where liquefaction has occurred during the earthquake, but only in a few cases, soil report in the zones of liquefaction are available. A wide spread damage because of liquefaction of soil deposit was observed during tile Niigata Earthquake of 1964 in Japan. A very systematic study on soil exploration in the zone of liquefaction was carried out and is well reported. Two sites were selected for the analysis from Niigata in the same area (i) where heavy damage occurred (ii) where no damage occurred. A case study was made using two different methods having different philosophy of analysis for prediction of possibility of liquefaction during an earthquake. The results of different methods are in good agreement with the observed behaviour where liquefaction was observed during the earthquake. But a wide controversy is observed between the two methods where liquefaction did not occur. The paper presents the case study
