Abstract: This paper aims to investigate liquefaction hazard assessment criteria available in practice which are obtained by geotechnical tests. In this study, developed indices for evaluation of liquefaction potential of susceptible soils under earthquake excitation were analyzed. From basic physical engineering indices resultant from in-laboratory investigations such as grain size distribution curves to the more sophisticated in-situ tests such as Downhole, standard penetration test (SPT), cone penetration test (CPT) and piezocone modified (CPTu) test, developed criteria were studied. Subsequently, liquefaction potential index (LPI) based-criteria for quantification of relationships among applicable in-situ tests were discussed. Finally, in reference to the data presented in this paper, appropriate methods such as geologic hazard mapping were suggested for further visualizing of coupled analyses with the aim of providing practical instrumentation of geological maps in liquefaction hazard assessment.
