“The phenomenon of pore pressure build-up following with the loss of soil strength is known as liquefaction (Committee on Earthquake Engineering, 1985)”. Liquefaction Potential Zones can be identified based on Superficial features (i.e. Preliminary Investigation), Sub surface features (i.e. Secondary Investigation) and Detailed Strength Parameters. The study of Mapping of Liquefaction Potential Zonation involves many Superficial Features like Geological, Geo-Hydrological, Geo-Morphological, Drainage, Age of Deposit etc. These studies give qualitative idea and indication of Liquefaction Susceptibility. The Sub surface investigation provides quantitative assessment of the Liquefaction Potentiality. Detailed analysis for mapping includes the strength parameters with all the above conditions and parameters as deciding factors and can be classified as: The Macro level of investigation is an overlook to the Liquefaction Susceptibility. While, the Micro level of investigation provides the preliminary Liquefaction Potentiality. Further, the liquefaction potentiality thus identified shall be analyzed with respect to the area specific strength characteristic and seismic activity. Here, the methods deciding the Liquefaction Susceptibility is discussed.
