摘要: 2023年2月6日,土耳其相继发生Mw7.8级和Mw7.5级大地震,土耳其和叙利亚两国遭受重大人员和财产损失。本文介绍了研究团队开展土叙地震应急响应的过程,在地球观测组织(GEO)合作框架下,与联合国卫星中心合作,通过夜光遥感技术开展震区损失评估的过程,主要包括调用卫星应急拍摄、数据处理和数据分析等工作。其中,利用NPP-VIIRS夜光影像对受灾城市进行了大尺度的损失评估,利用SDGSAT-1和Yangwang-1高分辨率夜光影像对阿德亚曼和安塔基亚两座严重受灾城市进行了精细尺度的评估。在此基础上,还介绍了如何通过国际合作框架向全世界发布土叙地震评估报告。该工作证明了夜光遥感能够开展重大自然灾害的应急响应,能够与日间遥感形成互补,从而对灾区进行快速和宏观评估。

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
