摘要

降雨引起的山体滑坡往往具有高度破坏性。审查和分析应急响应的原因、过程、影响和不足,对于改进灾害预防和管理至关重要。2024年7月21日晚至22日上午,埃塞俄比亚南部国家、民族和人民地区Gezei Gofa的Kencho Shacha Gozdi村遭遇强降雨,并引发两次山体滑坡。截至7月25日,该事件已造成至少257人死亡。本研究利用多源数据对滑坡进行了详细的表征。通过对滑坡灾害过程的分析,总结了主要经验教训,并提出了预防降雨地质灾害的建议。结果表明,降雨对滑坡的发生影响最大,而岩性和人类活动对滑坡灾害有促进和加强作用。尽管当地的救灾工作积极开展,但在应急工作中仍暴露出许多问题。这一分析为减轻降雨引起的地质灾害和提高应急响应能力提供了有价值的见解。

Disaster analysis and lessons learned from the July 22, 2024, Ethiopian landslide
Rainfall-induced landslides are often highly destructive. Reviewing and analyzing the causes, processes, impacts, and deficiencies in emergency response is critical for improving disaster prevention and management. From the night of July 21 to the morning of July 22, 2024, the Kencho Shacha Gozdi Village in Gezei Gofa, Southern Nations, Nationalities, and Peoples' Region, Ethiopia, suffered heavy rainfall that triggered two landslides. By July 25, this event had claimed at least 257 lives. This study presents a detailed characterization of the landslides using multi-source data. By analyzing the landslide disaster process, this study summarizes key lessons and provides suggestions for preventing rainfall-induced geological hazards. The results indicate that rainfall has the greatest impact on the occurrence of landslides, while lithology and human activities have promoted and strengthened the landslide disaster. Despite the active disaster response in the local area, many problems were still exposed in the emergency response work. This analysis offers valuable insights for mitigating rainfall-induced geological hazards and enhancing emergency response capabilities.
