Nepal’s count of deaths from the Aug. 26 glacier-linked flash flood reached 1,457 by Sunday, Oct. 11, with 4,720 people still missing, according to Nepal Police figures reported by Khabaree. Police had handled 1,335 bodies after identification and collected 3,427 DNA samples, Khabaree reports; that figure counts identified bodies released after checks such as DNA tests, a narrower measure than the 1,344 bodies police said they had recovered by Sept. 5. Reuters, in an Oct. 11 report on a separate new flood in Gorkha district, also put the August flood’s toll at 1,457, “with thousands still missing.”

Nepal’s National Disaster Risk Reduction and Management Authority gives a slightly different picture: more than 1,400 dead and over 5,200 missing, including 636 foreign nationals, the Kathmandu Post reported on Oct. 15. The Post says the government began a process on Oct. 9 to declare long-missing people dead. Police and disaster-authority counts differ, and this desk shows both.

Early counts ran lower. Nepal Police said they had recovered 1,344 bodies by 5 a.m. local time on Saturday, Sept. 5, with 4,898 people still out of contact and 8,631 rescued, Xinhua reports via China Daily. A day earlier, the disaster authority counted 1,294 dead and 5,053 missing, including 583 foreigners, Anadolu Agency reported; adding Chinese figures for Xizang of 31 dead and 531 missing, the agency put the combined toll at 1,325.

The flood began with a collapse high on the mountain, according to scientific agencies. The U.S. Geological Survey says “rapid slope failure involving a glacier” likely triggered the debris flow and flood in Langtang National Park near the Chinese border, and that the flow traveled about 100 kilometers along the Lende and Trishuli rivers, and released energy equivalent to a magnitude 5.2 earthquake. The USGS calls it unclear whether a landslide took in part of a glacier or the glacier itself collapsed. Anadolu reports that a glacier on Mount Langtang Lirung fractured at about 5,200 meters, setting off an ice-rock avalanche.

Floodwaters and mudslides hit Nepal’s Rasuwa, Nuwakot, Dhading and Kavre districts and the Kathmandu Valley, buried the Gyirong border crossing in Xizang, and struck at least six hydropower projects, Anadolu reports. Update: in mid-September, a World Weather Attribution study led by Imperial College London found unusually warm conditions before the collapse, according to the Guardian, which reports that the region has warmed by about 2C since pre-industrial times and that July and August 2026 ran the warmest on record locally.
