Satellite images before Nepal disaster showed warning signs

TL;DR - Satellite imagery showed accelerated movement of a glacier–rock mass days before its collapse in Nepal, which triggered a deadly flash flood. The observation suggests remote sensing could help identify warning signs for similar hazards.

• Pre-disaster images captured increasing movement in the unstable glacier–rock mass.
• The acceleration was visible only days before the collapse.
• The collapse caused a deadly flash flood.
• The limited content does not specify the satellite system, analysis method, or predictive reliability.
