Satellite images before Nepal disaster showed warning signs
Nature, Published online: 02 September 2026; doi:10.1038/d41586-026-02746-4 Images revealed the accelerated movement of a glacier–rock mass just days before it collapsed, triggering a deadly flash flood.
On 26 August, a devastating flash flood struck the Nepal–Tibet border region, triggered by the high-altitude collapse of rock and ice. The disaster has claimed over 1,000 lives and left more than 4,000 people missing, with the death toll likely to rise further. The incident highlights the potential dangers of extreme weather events exacerbated by climate change, such as the super El Niño currently causing widespread disruption.
Initial satellite images of the area revealed warning signs that could have provided valuable early notice of the impending disaster, should they have been monitored and acted upon in a timely manner.
