Abstract :Seismically active regions are always prone to be subjected to earthquake events and their eventual damages to urban areas. Liquefaction is one of the earthquake related incidents occurring within soil bodies during or after earthquake excitations. Gaining the knowledge of liquefaction potential for a site is exceedingly crucial in view of seismic risk mitigation, earthquake hazard assessments and future planning of urban areas. This study evaluates the liquefaction potential of Igdır city located in the eastern-side of Türkiye, having borderlines with three other seismically active countries in the region, Armenia, Nakhichevan and Iran. Soil data (i.e., Standard Penetration Test values, water table, water content, unit weight, grain size distribution and Atterberg limits) at the considered areas within the city is gathered from 85 boreholes. After investigating the fault lines around the city, the two possible maximum peak ground accelerations involved in this study are determined to be 0.393g and 0.225g. Liquefaction susceptibility maps of the areas at the two peak ground acceleration levels are designated in regard to liquefaction potential index and liquefaction severity index methods. The studied areas in the city exhibit various levels of liquefaction susceptibility as the severity is observed to be greater under the larger peak ground acceleration.Keywords : Sismik şiddet seviyesi, Standard Penetrasyon deneyi, Sıvılaşma potansiyel indeksi, Sıvılaşma şiddet indeksi, Sıvılaşma potansiyel haritası
