Title: The Slab Test – The Missing Link in Stability Testing?
Date: 2010
Authors: Kjetil Brattlien, Jo Gunnar Ellevold
Description: An avalanche is released when both the weak layer and the slab fails, still standard stability tests (e.g. CT, ECT) focus on the weak layer only. The ...

Title: Spatial Variations in Snowslope Stability: Insights from Observations During Active Control on the Milford Road, New Zealand
Date: 2009
Authors: Zach M. Guy, Karl W. Birkeland
Description: Slab avalanches initiate from relatively small (1-10m length) zones of basal weakness. Knowledge of the location of these “deficit zones”...

Title: How Snow Fails
Date: 2010
Authors: Ingrid Reiweger, Jürg Schweizer
Description: Dry-snow slab avalanches start with a failure in a weak layer below a cohesive slab. Avalanche release models start with an initial crack which may pr...

Title: New Insights Into Skier-Triggering of Slab Avalanches
Date: 2010
Authors: Joachim Heierli, Karl W. Birkeland, Ron Simenhois, Peter Gumbsch
Description: Most skiers trigger the slab avalanche in which they are caught. Preventing those accidents necessitates a better understanding of the factors contrib...

Title: The Effect of Additional Snow Load on Extended Column Test and Propagation Saw Test Results
Date: 2010
Authors: Ron Simenhois, Karl Birkeland
Description: The number of skier triggered dry slab avalanches typically increases during or shortly after snow loading events. However, field observations and res...
