Eight South Korean nationals are missing after a sudden flash flood and landslide struck the Lhasa-Rasuwa region of Nepal on Wednesday [1], [2].
The incident highlights the extreme vulnerability of infrastructure and personnel in Nepal's mountainous terrain, where rapid geological shifts can isolate entire groups of travelers and workers instantly.
The missing Koreans are employees of Doosan Enerbility and Korea South-East Power [1], [2]. A spokesperson for the Ministry of Foreign Affairs said that contact with the eight individuals was lost following the disaster [2].
Local reports indicate the disaster was widespread, with more than 380 travelers missing across the affected area [1]. The sudden surge of water and debris cut off communication and transport links in the Lhasa-Rasuwa region, complicating rescue efforts.
Experts noted that while the area may not be known for constant heavy rainfall, it remains highly susceptible to sudden disasters. Hwang Seok-hwan, a research fellow at the Korea Construction Technology Research Institute, said the region is a high-risk area where landslides can frequently trigger sudden flash floods [1].
Rescue operations are ongoing as authorities attempt to locate the missing workers and other travelers. The South Korean government is coordinating with Nepalese officials to establish communication with the missing employees [2].

This event underscores the operational risks for international energy and engineering firms working in the Himalayas. The combination of unstable terrain and unpredictable weather patterns means that even in areas not traditionally defined by heavy rain, the risk of 'debris flows'—where landslides block rivers and then burst—remains a constant threat to safety and infrastructure.
