The shape of rocks is a key factor in assessing rockfall hazard. This is the conclusion of a new SLF study.


From the 14th to 18th February 2022 SLF will be holding another international advanced snow and avalanche course in Davos. Register now!


To study types of snow and thus improve climate models, SLF snow researchers were on a polar expedition. Read more in the new DIAGONAL.


A new research consortium with participation of SLF-researcher Michael Lehning aims to promote decentralized renewable energy production.
