Learning from the Langtang tragedy

This case study examines the glacier collapse and catastrophic debris flow and flooding that struck communities across the Nepal–China border region on 26 August 2026.

The full 3D experience is not available on this device.This simplified page does not include the interactive terrain, mapped flood journey, evidence layers or geological investigation tools.

We recognise the devastating loss of life and the anguish of those whose loved ones remain missing. Our hearts go out to affected families, survivors and communities. Studying tragedies like this with care and respect can help strengthen warning systems and prepare communities for similar cascading hazards.

The full explorer requires WebGL 2. Updating your browser and enabling hardware acceleration may make it available.
