Avalanche accidents in summer - Even small snowslides can have fatal consequences

It may be summer, but avalanches still pose a very real threat in some parts of the Swiss Alps. To prevent accidents, a few rules should therefore be followed when hiking or climbing in the mountains.


Avalanche Forecasters Consultation - Coordination within Europe

The avalanche warning services operating in Europe have undertaken to develop common standards for their activities. Their General Assembly recently adopted a resolution to revise the designations of avalanche sizes.


Settling of snow - How does snow metamorphism influence settling?

Why do different types of snow settle at different rates? Lab experiments show that settling depends on the snow structure.


Landslides - Biodiversity offers protection

Landslides repeatedly cause major damage in Switzerland. A report by the WSL produced within the framework of the National Research Programme "Sustainable Use of Soil as a Resource" (NRP 68) describes how soil stability can be improved long-term with relatively little input.


Rock fall in the mountains - Online form

In the context of our research we are collecting information on rock fall in permafrost areas. If you observe rock fall in the mountains, we would be grateful for your feedback using our online form.


Severe weather 2016 - Significant damage on the north side of the Alps

Severe weather events in Switzerland gave rise to property damage of about CHF 100 million in 2016. This was revealed by the annual analysis of the national storm damage database maintained by WSL.


WSL-Magazine - Nr. 1/17 has been published

The latest issue of the WSL magazine DIAGONAL has been published. It focuses on the key theme "Forest Reserves: Where nature has priority".


"Weekly report" - Monthly during summer

New snow and dry avalanches in high alpine regions, snow melt and wet avalanches at high altitudes. This is how the weekly report describes the snow and avalanche situation of the second half of May.


Avalanche bulletin - End of bulletin season

Until next autumn, avalanche bulletins are published by the SLF only in the event of heavy snowfall. You can be notified that an avalanche bulletin has been published via SMS or RSS feed.


Mountain forests of the Alps - Natural disturbances on the rise

An international research team have produced a synopsis of long-term change in the forests of the Alps. Their work shows that rising timber stock in mountain forests has increased the incidence of natural disturbances.
