Liquefaction failure under earthquake loading is a recurrent geotechnical hazard for cohesionless saturated soils. Loss of shear strength, reduction of bearing capacity, and enormous settlements for infrastructures are among the most common consequences. Similar to the occurrence of liquefaction hazards, site-specific analysis of liquefaction has been commonplace following a stress-based approach. An attempt has been made in this paper to establish the importance and validity of a method that considers the imparted energy due to ground shaking. Arias Intensity approach takes up the acceleration time history of an earthquake to account for the load inducing liquefaction. Borehole data from within Agartala city were considered to characterize the liquefaction resistance. Since Agartala lies in North-East India, which has been categorized under zone–V by BIS-1893(Part 1)-2002, it has been considered for the test owing to its high rate of seismicity. This paper considers an earthquake event of moment magnitude MW = 5.6 as a base case that induced liquefaction in and around Agartala in 2017. A thorough liquefaction potential index evaluation procedure is provided in this paper.
