 The Turkey-Syria earthquake on February 6, 2023 caused significant losses including casualties, road damage and building collapses. We used satellite imagery to map and quantify the areas impacted by the earthquake at various distances and directions. We also explored the relationship between the average changes in the nighttime light intensity, population density and building density using the local indicators of spatial association, LISA, method. In Turkey, Hadi, Gaziantep and Sanliurfa experienced the greatest losses. Arrakha was the most affected city in Syria, with the highest loss rate. A correlation analysis revealed that the number of injured populations in the provinces in Turkey and the number of pixels with a decreased nighttime light intensity exhibited a linear correlation with an r-squared value of 0.7395. Based on the changing value of the nighttime light intensity, the areas with large losses were located 50 kilometers from the earthquake epicenter in the east by south and north by west directions and 130 kilometers from the epicenter in the southwest direction.
