Comprehensive Inventory of Coseismic Landslides triggered by the 2023 Kahramanmaraş Earthquake Doublet, Türkiye

How to cite If you use this dataset, please cite the associated Data Descriptor published in Scientific Data: Yılmaz, A., Tanyaş, H., Karabacak, F. et al. Comprehensive Inventory of Coseismic Landslides Triggered by the 2023 Kahramanmaraş Earthquakes, Türkiye. Sci Data (2026). https://doi.org/10.1038/s41597-026-08188-x This dataset provides full-footprint polygons of coseismic landslides triggered by the February 6, 2023, Kahramanmaraş earthquake doublet in Türkiye. Mapping was conducted through expert visual interpretation of high-resolution pre- and post-event aerial imagery (0.3 m), supported by a DEM-based pre-earthquake geomorphic inventory covering approximately 80,000 km². Each coseismic landslide polygon includes classifications for movement and material type. In addition to the coseismic inventory, the dataset also includes a preseismic landslide inventory representing landslides that existed prior to the earthquake sequence. Version 2.0 adds a preseismic landslide inventory and an updated README. This dataset contains landslide polygon inventories and associated attribute tables created for the 2023 Kahramanmaraş earthquake sequence. The original third-party aerial photographs, satellite imagery, and DEM products used as input data for landslide mapping are not redistributed as part of this dataset.
