Seismic signal characterization of snow avalanches using distributed acoustic sensing in Grasdalen, western Norway [PDF]
Natural Hazards and Earth System SciencesWe show the use of distributed acoustic sensing for analyzing seismic signals from snow avalanches. For three winter seasons, we continuously recorded seismic data using distributed acoustic sensing (DAS) on a standard telecommunication fiber along a ...

Sustainable Development, EarlyView.ABSTRACT Risk management has evolved to analyze risks in a systemic way, integrating local knowledge with the abstract concept of resilience, which is now an imperative for vulnerable and exposed communities. However, existing decision‐support tools are mainly focused on technical‐functional aspects and, although based on rigorous and scientific ...

High Voltage, EarlyView.ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Modelling the system behaviour of wet snow avalanches using an expert system approach for risk management on high alpine traffic roads [PDF]
Natural Hazards and Earth System Sciences, 2005 The presented approach describes a model for a rule-based expert system calculating the temporal variability of the release of wet snow avalanches, using the assumption of avalanche triggering without the loading of new snow.

Presoja varovalnega učinka gozda pred snežnimi plazovi
Acta Silvae et Ligni, 2016 The road leading to the Vršič Pass is threatened by snow avalanches, and the forests above it are performing a protective function against them. We analysed potential hazard to the road and forests above it from snow avalanches, and evaluated the ...

Impact of climate change on snowpack and avalanches in Slovenia: The Soča Valley case study
Geographia Polonica, 2023 The article discusses avalanche occurrence in the Slovenian Alps (SE Alps) in the context of climate change. It analyses the relationship between the North Atlantic Oscillation and maximum snow depth over the last two centuries, and the relationships ...

Animal‐Mediated Dispersal and Clonal Growth Drive Prunus cerasus Invasion in Andean Temperate Forest
Integrative Zoology, EarlyView.Prunus cerasus reproduces by clonality and by seed dispersal and germination. P. cerasus is invading Patagonian protected areas. The relative relevance of germination and clonal reproduction changes along the time of P. cerasus arrival at a site. Seed dispersal by foxes is primarily responsible for the spread of P. cerasus to new areas.

Coupled Snow Cover and Avalanche Dynamics Simulations to Evaluate Wet Snow Avalanche Activity [PDF]
Journal of Geophysical Research: Earth Surface, 2018 We present physics‐based snowpack simulations for four snow seasons with detailed wet snow avalanche activity records. The distributed, spatially explicit simulations using the Alpine3D and SNOWPACK model show that the simulated snowpack in the release areas of documented wet snow avalanches often exhibits its first wetting of the season on the release

High resolution radar imaging of snow avalanches [PDF]
, 2018 Snow avalanches are a complex type of gravity driven mass-movement phenomena and can exhibit very different flow dynamics. They may flow as a dilute and fast powder snow avalanche, or cohesive snow may cause a dense and slow gliding motion.

Avalanche hazard and control in Kazakhstan
Лëд и снег, 2015 In Kazakhstan, area of 124 thousand km2 is prone to the avalanche hazard. Avalanches are released down in mountain regions situated along the eastern boundary of Kazakhstan.
