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: Some Insights Into Fracture Propagation in Weak Snowpack Layers
Date: 2010
Authors: Joachim Heierli, Alec van Herwijnen, Peter Gumbsch, Michael Zaiser
Description: Dry snow slab avalanches form when fracture, once initiated in a weak snowpack layer, propagates over large distances, progressively debonding a vast ...

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: Characterizing Microstructural Arrangement and Effective Properties of Dry Snow: Thermal Conductivity
Date: 2010
Authors: Richard H. Shertzer, Edward E. Adams, Martin Schneebeli
Description: A microstructural quantity, the contact tensor, is introduced to characterize the directional arrangement of bonding in the snowpack. The contact ten...
