Liquefaction risk maps were created in Lala Hüseyin Paşa, Gaybiefendi and Meydan neighborhoods in Kütahya city center. A total of 112 boreholes were investigated by helping the SPT results (Standard Penetration Test) and soil parameters. Matasovic/Vucetic or Dobry/Matasovic model was used in the analyzes according to soil class. For analyzes, 11 earthquake were determined. The determined earthquakes were scaled with the Peak Ground Acceleration (PGA) of the neighborhoods and 44 earthquake data were found. Every borehole was analyzed with these 44 earthquake data in the Deepsoil 6.1 program and liquefaction risk maps were created. The average liquefaction risk data for neighborhoods were created by averaging the results obtained. The liquefaction data found show different results for earthquake levels. Liquefaction analysis results according to Earthquake Level-2 (DD-2), which the regulation accepts as a design earthquake; The average liquefaction risk was calculated as 23% in Lala Hüseyin Paşa neighborhood, 40% in Gaybiefendi neighborhood and 35% in Meydan neighborhood. While the highest risk of liquefaction occurred in the Meydan district with 68% according to DD1, the lowest risk was calculated in Lala Hüseyin Paşa District as 3% according to DD4. The liquefaction maps created can enable the necessary precautions to be taken for the construction in the neighborhoods.
