At the conclusion of the International Mountain Conference (IMC) in Innsbruck, a special session co-organized by Christian Huggel (EClim, University of Zurich), Mylène Jacquemart, and Jan Beutel brought together close to 20 presentations focused on the glacier avalanche disaster in Blatten, Switzerland.

In less than four months, researchers from Switzerland, France, Italy, Austria, Germany, and beyond have mobilized an impressive body of work. This session offered a unique opportunity to share early insights and ongoing investigations related to one of the most complex high-mountain disasters in recent Swiss history.

Topics covered included:

• Reconstruction of the sequence of events and emergency response.
• Onsite and satellite-based monitoring of slope deformation and avalanche dynamics.
• Terrain analysis and volume estimation of slope failures and ice-rock avalanches.
• Dynamic simulations using various avalanche models.
• Glacier mechanics and impacts of debris loading on failure thresholds.
• Seismological signal interpretation during the event.
• Permafrost temperature modeling over 150 years.
• Attribution of glacier and slope failure to anthropogenic climate change.

Beyond the technical presentations, the session spurred critical discussions on:

• Cross-sector collaboration among authorities, scientists, and private actors.
• Limitations and future potential of multi-instrument monitoring in the Alps and globally.
• Research gaps, especially regarding post-disaster reconstruction and long-term habitability.
• The need for greater involvement of social sciences.
• Stark contrasts in risk preparedness between well-resourced countries like Switzerland and more vulnerable mountain regions such as the Himalayas.

“It was inspiring to witness the level of engagement and commitment from the international community — a strong signal of readiness to face the growing challenges in high mountain regions,” said Huggel.
