This document evaluates the liquefaction potential of sabkha soil in the Aziziyah area of Khobar, Saudi Arabia. Standard penetration tests were conducted at 20 borehole sites in sabkha soils to depths of 15-25 meters. The soils generally consisted of very loose to loose, saturated sandy soils from the surface to depths of 10-15 meters underlain by soft silts and then denser sands and clays. The liquefaction potential was assessed using the simplified procedure of Seed and Idriss based on corrected SPT N-values. Factors of safety against liquefaction were calculated for earthquake magnitudes of 5.5. The results showed that sabkha soils in the upper 10-12 meters have
