In memory of the late WSL Director Koni Steffen, a symposium on cryosphere and climate will be held from 21-22 October 2021. Register now.


How will climate change affect the water situation in Switzerland? This question was the focus of the research programme Hydro-CH2018.


February 11 is International Day of Women and Girls in Science! We asked WSL female researchers why they chose their profession.


Avalanche simulations provide a possible explanation for the mysterious death of nine ski hikers in the Ural Mountains 60 years ago.


The Swiss stone pine may be unable to adapt fast enough to climate change, a genetic study finds, and could become locally extinct.


Across six research groups, the CERC will investigate issues arising from climate change, extreme events and natural hazards in alpine regions.


Snowshoeing is becoming more and more popular, but the same rule applies as with other winter sports: beware of avalanches.


The SLF issued its first avalanche bulletin on 21 December 1945. Major changes and continuous improvements have been made over the years.


Who is behind the avalanche bulletin and what do avalanche forecasters do in summer? In the video interview, three of them give exciting insights.


The avalanche prevention portal now includes new functions, including the automatic recognition of potential cruxes.


Martin Ruggli is a mountain guide and SLF observer. He explains why it's crucial for people to stay alert whenever they're outdoors in the snow.


Paulon Massy has been an observer for the SLF for an incredible 47 years. He was once buried by an avalanche while working as a ranger.


Filippo Genucchi is an SLF observer and a safety officer for the Lukmanier Pass. He trusts in the quality of the avalanche warnings.


Jon-Andri Bisaz reports observations to the SLF from the Upper Engadine region. He also benefits from the role in his work as an avalanche consultant.


Ruth Moor-Huber from Gadmen is one of only a few women working as observers for the SLF. She tells us what she likes about the role.


Nearly 200 observers throughout Switzerland send snow and avalanche reports to the SLF. This week we are introducing you to six of them.


Heavy snowfall is predicted for the southern flank of the Alps and the Engadine. The avalanche bulletin appears again with the interactive hazard map.


We celebrate the anniversary in December with a series of news items. Find out here, for example, how the avalanche bulletin is produced.


Why do we investigate extreme events? In order to find ways of dealing with what in future may be normal. Find out more in a DIAGONAL interview.


Thanks to research, monitoring and warning systems, people are better protected from rock falls today. Read more about it in a new DIAGONAL article.
