weaklayer
A weak layer is a layer within a snowpack that has comparatively low shear strength relative to the layers above or below it. This weaker plane can act as a potential failure point when the overlying snow is subjected to additional load, such as new snowfall, wind deposition, or warming.
Weak layers commonly form through metamorphism and bonding processes that reduce cohesion between snow grains. Depth
Typical weak-layer types include depth hoar, buried surface hoar, faceted grain layers, and crusts with weak
Role in avalanches: A weak layer can serve as the fracture plane for slab avalanches when the
Identification and testing: Snowpack analysis, including snow pits and stability tests, helps evaluate weak-layer presence and
