Occurrence of liquefaction in saturated sandy soils with low density is possible. During an earthquake with the vibratory forces applied to the soil, tendency to reduce the volume causes pore water pressure to increase. Provided that this increase of pressure is continued so that the effective stress reaches zero under the equivalence with total stress, the soil would lose its loading power and in bearing higher loads, it acts as if it is condensed liquid, the result of which would be settlement, rotation and huge marginal displacements which could be easily sunken in the ground. The purpose of this article is to evaluate the possible liquefaction is caused by the earthquake induced forces. Results indicate that the decrease of resultants in strength and rigidity, causes Thrust shear stresses to operate in the direction of differentiating shear forms which would ultimately lead to Swelling of the soil and thus the reduction pore pressure.
