Field investigations and numerical modeling of the 28 May 2025 Blatten landslide suggest basal liquefaction and ice-related friction reduction could have contributed to its large mobility.
A framework for climate change attribution for the 2025 Blatten rock slope failure and glacier collapse
We present a framework for the attribution of the 28 May 2025 Blatten glacier collapse to anthropogenic climate change, and show to what extent the attribution is feasible.
The Blatten rockslide: chronology, recorded data and open questions
We present a brief chronology of the event, the data collected during the event and the relevant practical questions, which we hope to answer together with the scientific community.
The May 2025 rock-ice avalanche of Blatten (CH): Preliminary seismologic and permafrost studies and outlook for interdisciplinary research
We present preliminary seismologic and permafrost studies on the May 2025 rock-ice avalanche of Blatten, as well as an outlook of potential interdisciplinary research avenues.
Monitoring of the “Kleines Nesthorn” and of the Birch Glacier before and during the rock avalanche in Blatten
The presenters will show you at the example of Blatten how a monitoring solution for a natural hazard can look like and what challenges we face.
From Himalayas to Alps: Analyzing Patterns in Kedarnath, Chamoli, Dharali, and Blatten Disasters
Climate warming increases mountain hazards. Unstable slopes, heavy rain, and risky development fuel disasters. Monitoring, zoning, and early warnings can reduce losses and protect communities.
Granular flow modelling of the May 2025 Blatten, Switzerland Ice–Rock Avalanche
We performed post-analysis on the Blatten event by constraining numerical modeling results with the force-time function inverted from remote seismic stations as well as the DEM analysis on the final deposits.
Analysis of glacier behavior, runout dynamics, and event magnitude from orthophotos and DEM differencing
We have analyzed a number of digital elevation models (DEMs) and orthophotos to reconstruct the pre-event behavior of Birchglacier, the volumes that were involved in the catastrophic collapse, as well as the dynamics of the runout of the rock-ice avalanche.
