Abstract: On February 6, 2023, Mw7.8 and Mw7.5 earthquakes hit Turkey successively, causing heavy losses of lives and property in Turkey and Syria. This letter introduces the research team at Wuhan University, under the framework of the Group on Earth Observations (GEO), collaborated with the United Nations Satellite Centre to implement damage assessment of the earthquake through night-time light remote sensing. The process mainly includes the satellite emergency photography, data processing and data analysis, etc. The NPP-VIIRS night-time light images were used to conduct a large-scale loss assessment of the affected cities, and the SDGSAT-1 and Yangwang-1 high-resolution night-time light images were used to carry out fine-scale analysis of Adiyaman and Antakya, which are two severely hit cities. On this basis, the article also introduces how to release the Turkey-Syria earthquake assessment report to the world through the framework of international collaboration. This work proves that night-time light remote sensing can carry out emergency response to major natural disasters, and can complement day-time remote sensing to conduct rapid assessment of disasters at large scale.

Key words: Turkey-Syria earthquake, night-time light remote sensing, rapid response, disaster assessment, United Nations
