This paper is concerned with the evaluation of Baghdad soil liquefaction potential under earthquakes effect. Data of soil investigation reports such as borehole total depth, water table level, total unit weight, standard penetration number and fines percentage were used. Data for 630 boreholes represent 200 site location points for many different types of projects spread all over the city have been chosen and analyzed using LiquefyPro software. Two user factors of safety and two options for fines correction have been used. Six earthquake magnitudes (M=4 to 6.5 with 0.5 interval) have been chosen to analyze the data. Only 121 points show susceptibility to liquefaction. The final output is shown in tables and the points are shown on GIS maps. The results state that the effects of earthquake induced liquefaction should be taken in consideration in future design.
