This paper reports research currently being conducted on the correlation of permant lateral ground deformation (D_H) due to earthquake-induced lateral spreading caused by liquefaction of saturated sand, with static cone penetration (CPT) point resistance. Both lateral spreading tests for various sand relative densities and degrees of preshaking. These correlations will provide the basis for CPT-based charts to predict D_H in the field. These charts are also expected to provide threshold combinations of CPT value, soil depth, ground slope, and strong motion input for which D_H is small and can be neglected even if the soil liquefies, due to its dilatnat shear stress-strain response.
