In the recent past, liquefaction is considered as one of the major geotechnical hazards in worldwide caused due to earthquakes in saturated fine sand deposits. Liquefaction of soil results in catastrophic damages to life and property as well. Keeping this in view, prior anticipation of occurrence of liquefaction is required to safeguard the infrastructure and life against the adverse effects of liquefaction, especially in coastal areas where abundant saturated sand deposits are present. This study has been carried out to determine the evaluation of liquefaction potential and liquefaction potential indices in the selected areas of Visakhapatnam city by estimating the factor of safety based on field SPT N values as per IS 1893 Part 1 2016 and Idriss & Boulanger (2008) methods. Based on the study, it was concluded that all the study areas, other than study area 4, are not prone to liquefaction under the considered magnitudes of earthquakes with respect to present seismic zoning 2. However, the subsoil profiles of all study areas indicated high risks against liquefaction, corresponding to seismic zones 4 and 5.
