On February 6th, 2023, a sequence of devastating earthquakes hit the south and southeastern part of Türkiye. Numerous secondary hazards were triggered in the region, including thousands of landslides. This study investigated the landslides triggered by the 6 February 2023 Kahramanmaras Earthquakes. On the February 7th, the General Directorate of Mapping, Türkiye initiated several aerial photogrammetric flights and continued for several days. Although the adverse meteorological conditions affected the image quality, valuable data with a nominal resolution of 25 cm could be produced over an area of 108,627 km2. By comparing post-earthquake aerial orthophotos with pre-earthquake imagery stored in archives, we identified a total of 2,596 landslides, presumably triggered by the events, and analyzed their characteristics. This paper presents the methodology of the inventory preparation, characteristics of the landslides, and potential use cases of the inventory. The co-seismic landslide inventory produced here is also shared in the form of supplemental data.
