Likelihood of liquefaction at different probability (Iwasaki 1978; Iwasaki et al. 1982)

Liquefaction potential index ($\mathbf{L}\mathbf{P}\mathbf{I}$)	Description	Further requirement
$\mathrm{LPI}$> 15	Very high chances of liquefaction	A thorough examination, also. countermeasures are required
5 < $\mathrm{LPI}$  ≤ 15	High chances of liquefaction	In the case of structures, a detailed study is required. In most cases, a liquefaction countermeasure is important
0 < $\mathrm{LPI}$  ≤ 5	Low chances of liquefaction	A more thorough study is required, particularly for infrastructure projects
$\mathrm{LPI}$= 0	Very low chances of liquefaction	A thorough examination is not required
