Soil liquefaction can induce significant financial damage during earthquakes. Based on in-situ testing results, several methods for soil liquefaction evaluation have been developed in the past. Due to continuous and precise records, the piezocone (CPTu) has gained wide acceptance among other in-situ tests. In this paper, various analytical and descriptive liquefaction assessment approaches have been evaluated. Ten CPTu soundings derived from different sites that have experienced earthquakes were used for evaluation of the current approaches. Liquefaction assessments based on analytical methods presented in the past are rather complex. In this study, by using the data from these ten CPTu soundings, an area called the ``zone of potentially liquefiable soils'' was introduced over Robertson(1990) and Eslami-Fellenius(2004) soil behavior type charts. This area can indicate the soil types that are most susceptible to liquefaction. The results of liquefaction prediction by the proposed approach demonstrate good accuracy and consistency with the current methods.
