This paper reviews the previous related research on liquefaction susceptibility to provide critical literature recommendations on liquefaction susceptibility assessment. The developments of liquecation susceptibility evaluation in last 40 decades are included. Modified Chinese Criteria is the best known indicator which globally recognized. Due to the existing literature gaps of liquefaction susceptibility of fine soils and the deviation of actual liquefaction cases in past earthquake, reexamination and modification is essential to ensure the usability of Modified Chinese Criteria. The controversy and confusion of the fine grained soils behavior after being disturbed by cyclic load is complex. The use of clay fraction as a controlling parameter is the main contribution of inaccurate in the evaluation. Plasticity index is the most suitable controlling parameter to replace the clay fraction in Modified Chinese Criteria. Plasticity index can confidently distinguish the fine grained soils behavior for the ease of assessment. Fine grained soil could be either “clay-like” which expected to be cyclic softening or “sand-like” that susceptible to liquefaction phenomena. With this the cyclic behavior of fine grained soils are well understood and this lead to a more precise and confident output. Thus, Chinese Criteria should replace fine percentage with plasticity index in the assessment.
