Nepal Flood Kills 633, Leaves 9 Korean Workers Missing — A Glacier's Warning

Korean firms carefully price in political and currency risk when they build overseas — this disaster shows climate risk has been the blind spot.

What happened

On August 26, a massive flood struck Rasuwa district in north-central Nepal. It was first reported as a landslide triggered by a magnitude-4.4 earthquake, but analysis by the US Geological Survey (USGS) later found that a large glacier collapse and debris flow had produced a seismic-like signal instead.

The flood, which struck the border area between Nepal and Tibet, China, had killed 633 people as of August 29 (626 in Nepal, 7 in Tibet) and left nearly 3,000 missing (2,426 in Nepal, 554 in Tibet). Nepali authorities said they had deployed 15,000 soldiers and police and rescued 4,451 people so far.

Korean nationals were among those affected. Of 19 workers from Doosan Enerbility and Korea Southeast Power (KOEN, a state-run utility) building the Upper Trishuli-1 hydropower plant on the Trishuli River, 70km north of Kathmandu, 10 were safely evacuated by helicopter. The remaining 9 — 6 from Doosan Enerbility and 3 from KOEN — have been missing for four days.

Why it matters — where overseas construction meets climate risk

This is more than a natural-disaster story, because the missing are not tourists but workers on a state-linked infrastructure project. Upper Trishuli-1 is a $647 million (about 890 billion won) hydropower plant with 216MW of capacity, which broke ground in January 2022 and was due for completion by the end of this year. KOEN was set to operate it directly for 30 years after completion — meaning a Korean state-run utility has decades of exposure tied to an overseas asset now caught in the middle of a disaster.

The project was structured to manage political and financial risk from the start, with KOEN and the International Finance Corporation (IFC) joining as co-developers early on. Yet the disaster suggests that while political and financial risk was carefully assessed, climate-driven hazards like glacial lake outburst floods may not have been adequately factored into the project's design.

By the numbers

The death toll nearly quadrupled in three days — a sign both that the initial scale of the disaster was underestimated in real time, and of how slow rescue and counting are in such rugged terrain.

The debate — unforeseeable disaster, or manageable risk?

Experts are divided. Some argue the disaster was such an unusual, compound event — initially mistaken for an earthquake — that it was effectively impossible to predict. Even USGS first classified it as seismic before revising its assessment to a glacier collapse.

Climate scientists offer a different read. Himalayan GLOFs have already been observed at a rate of about 1.3 per year, and research estimates roughly 15 million people worldwide are exposed to this risk. In other words, this particular event was unusual, but this type of event has long been anticipated in the literature — which is why some argue climate risk assessment should have been built more rigorously into the project's design.

Views on the corporate response also differ. Doosan Enerbility moved quickly, with its CEO traveling to the site and setting up an emergency task force. But whether the emergency evacuation and communication systems at a remote mountain construction site were adequate in the first place remains unverified.

What's next

The immediate priority is confirming the fate of the 9 missing workers. The government has dispatched 20 members across two rapid-response teams, searching high-altitude terrain by helicopter and drone — work made slow by washed-out roads.

In the medium term, how overseas infrastructure projects assess risk is likely to come under scrutiny. Expect louder calls to quantify climate-disaster risk in feasibility studies and insurance design, the same way political and currency risk already are. As Korea keeps expanding overseas orders in nuclear power, energy and plant construction, this disaster may prompt a different question than simply how much more it can win — namely, what risk it is carrying when it does.
