The aim of this study is to evaluate the liquefaction potential of Aziziye District in Erzurum Province and to determine the seismic safety of the region in terms of soil properties. In this context, the liquefaction potential of the study area was calculated using the methods proposed by Iwasaki et al. (1982) and Sönmez and Gökçeoğlu (2005). As part of the field studies, boreholes were drilled at designated points and Standard Penetration Test (SPT) was applied. In addition, disturbed and undisturbed soil samples taken from the research pits were subjected to consistency limits, natural and saturated unit weight, sieve analysis, and hydrometer tests in the laboratory. Using all the data obtained from the field and laboratory tests, liquefaction potential analyses were performed according to the criteria of Iwasaki et al. (1982) and Sönmez and Gökçeoğlu (2005). The liquefaction potential for Erzurum province was evaluated using the Liquefaction Potential Index (LPI) and Liquefaction Severity Index (LSI) methods, and a liquefaction potential map was prepared in a GIS environment according to different earthquake scenarios. As a result of the evaluation of the data obtained within the scope of the study; it was determined that the average SPT-N value was 25.36, the natural unit weight was 16.20 kN/m³, and the saturated unit weight was 17.45 kN/m³. Furthermore, the plasticity index was determined to be 13.8%, the clay content 11.12%, and the fine grain ratio 32.34%. In the liquefaction analyses performed using these soil properties, the liquefaction potential at different points of the study area was calculated according to the methods of Iwasaki et al. (1982) and Sönmez and Gökçeoğlu (2005). The liquefaction potential for Erzurum province was evaluated, and maps were prepared according to different earthquake scenarios. According to the results obtained from field and laboratory studies, it has been determined that the probability of liquefaction occurring is high at the SK-1, SK-4 and SK-7 borehole locations in the study area, while the liquefaction potential is at a very low level at the SK-2, SK-3, SK-5 and SK-6 locations.
