On the universality of power-law exponents for snow avalanches

Abstract:

Snow avalanches are a significant natural hazard in the world's mountainous regions. In the United States, snow avalanches kill more people on an average annual basis than other earth movement hazards such as landslides or earthquakes. Understanding the relationship between avalanche frequency and magnitude can be helpful for avalanche planning and zoning, in addition to improving our understanding of these complex phenomena. Previous research demonstrates that frequency/magnitude relationships for snow avalanches can be described by power-laws, similar to other natural hazards like earthquakes, rockfalls and forest fires. In fact, in these early investigations some researchers have suggested that a universal power-law exponent might exist for snow avalanches. This poster utilizes an extensive snow avalanche dataset covering nearly 30 avalanche seasons at 29 different locations to examine …
