On January 24, 2020, an earthquake with the Mw of 6.8 occurred on the East Anatolian Fault Zone in Elazig Province, Turkey, and triggered many landslides. Even though Turkey is in a high seismic zone and has highly susceptible areas to landslides, event-based inventories of landslides triggered by earthquakes have not yet been published in the international literature. The purpose of the present study is to compile the landslide inventory triggered by the Elazig earthquake. A novel approach involved change detection analyses was applied by using high-resolution 3D digital surface models (DSMs) obtained from pre- and post-earthquake aerial photos. In the study, a total of 328 landslides sized between 133 m² and 3 × 10⁶ m² were mapped by visual interpretations. The rollover effect and fractal dimension of the failures were obtained as 3600 m² and –1.48, respectively. The total landslide area including new active zones developed after 2018 within the existing mass was calculated as approximately 8 × 10⁶ m². According to the volumetric change analyses, the displacements were between –17.66 m and 14.11 m. It is evident that using photogrammetric methods to produce very high-resolution DSMs enables precise determination of landslide activity after an earthquake and increases the quality of the inventory. Consequently, application of the surface comparison methods immediately after large earthquakes provides great benefits in obtaining new landslide data open up important possibilities for a better understanding of the mechanism of landslides triggered by earthquakes, thus minimizing losses sourced from them.

2020年1月24日，土耳其Elazig省东安纳托利亚断层带发生了6.8兆瓦级地震，引发了许多山体滑坡。尽管土耳其处于地震高发区，并且是滑坡的高度敏感地区，但国际文献尚未发布由地震触发的基于事件的滑坡清单。本研究的目的是编制由Elazig地震引发的滑坡清单。通过使用从地震前和地震后的航拍照片获得的高分辨率3D数字表面模型（DSM），应用了一种涉及变化检测分析的新颖方法。在研究中，共有328个滑坡，大小在133 m ²和3×10 ⁶ m ^2之间通过视觉解释进行映射。失效的翻转效应和分形维数分别为3600 m ²和–1.48。包括现有质量在内的2018年后开发的新活动区在内的滑坡总面积约为8×10 ⁶ m ²。根据体积变化分析，位移在–17.66 m和14.11 m之间。显然，使用摄影测量方法来生成非常高分辨率的DSM可以精确确定地震后的滑坡活动，并提高了清单质量。因此，在大地震发生后立即应用地表比较方法，对于获得新的滑坡数据提供了很大的好处，为更好地了解地震引发的滑坡的机理开辟了重要的可能性，从而最大程度地减少了因地震引发的滑坡。
