El Hosri et al (1984) performed tests on six silt specimens in undisturbed state obtained from depths of 20 and
40 m at two sites. The soils tested were mainly silts with traces of clay or clayey silt (ML-CL or ML-MH) with
PI between 5-15% except one sample which consisted of silty sand. Table 1 lists cyclic stress ratios (CSR) for
liquefaction in 20 cycles and the corresponding void ratios.
