Videos for avalanche planners

The videos on this page posted since ~2015 are by Bruce Jamieson ( and colleagues. Some of the earlier videos on this page are links to videos made by Bruce Jamieson and ASARC colleagues ( The links to all these videos can be shared freely and the videos used for any purpose, including commercially, provided the content and authorship are not altered.

A successful avalanche operation starts with good planning. This 9-minute video highlights some aspects of avalanche planning for those who work in avalanche operations. On many planning projects, the planning team includes practitioners with operational experience. Bruce Jamieson, 2020, CC BY-ND.

How do snow avalanches differ from other slope hazards?

By understanding the differences between snow avalanches and other slope hazards, the authors of Planning Methods for Assessing and Mitigating Snow Avalanche Risk hopefully made it accessible to specialists who plan for other slope hazards. Bruce Jamieson, 2019, CC BY-ND.

ISO 31000 and avalanche mitigation projects

This presentation is similar to a paper presented at the 2013 ISSW in Grenoble, France.

Quantitative risk analysis for a structure in an avalanche path

This video presents a simplified quantitative risk analysis for an object of value that is fixed in a snow avalanche path. The concepts can be adapted moving objects such as vehicles or people and for other mass movements.

Demystifying the Monte Carlo method with a simple example

This is a sequel to the video on quantitative risk analysis for a structure in an avalanche path. Bruce Jamieson, 2016, CC BY-ND.

Has the snow climate changed in western Canadian mountains?

Climate change has been a focus for the avalanche world over the last few years. The Asarc group at the University of Calgary recently contributed two papers to the discussion, which we have summarised in this video. 2015,, CC BY-ND.

So, was it a size 5? Reflections on the Canadian Avalanche Size Classification

Hopefully, this will spark discussion on how to classify avalanche size, especially for big avalanches. There is also another discussion video on a practitioner survey and the use of half sizes.

Vulnerability: Caught in an avalanche – then what are the odds?

This presentation is based on a paper by Bruce Jamieson and Alan Jones for the ISSW in Alaska in September 2012. It reviews risk concepts then summarizes quantitative vulnerability for buildings, people in buildings, people in vehicles and people in the backcountry.

Example of Bayesian updating applied to pre-season planning for an avalanche forecasting program

This video uses a simple avalanche forecasting problem for a ski area to illustrate Bayes Rule, which is a method for updating a numerical probability based on new information. It is applied to pre-season planning - helping to set the threshold precipitation for explosive mitigation; however, Baysian updating can also be applied more frequently, e.g. on a day by day basis.
