ÖZ: In this research, engineering properties of Lara-Kundu coastal plain soils and liquefaction potential of thesands in the region have been investigated. For this purpose, samples which were taken at an interval of 1.5 m from 20 boreholes of 20 m depth, were investigated in the laboratory, and soil index, strength and compressibility properties were determined. In situ tests which are SPT and CPT were executed. Dense sand is the main soil type of the region, and also in some parts loose sand, clay and peat are also available. Carrying out seismic hazard analysis, a peak ground acceleration contour map has been generated. Probabilistic liquefaction potential analysis was performed to search for liquefaction potential of sand layers in the soil profile. LSI (Liquefaction Severity Index) value was calculated with the help of PL values which were determined for every depth of the searching location. By using all the data and Geographical Information Systems (GIS) technique; liquefaction severity index (LSI) map of the soils of Lara - Kundu Region has been created.
