• Can the propagation speed of snow avalanches be determined by seismic methods? 

      Vilajosana, I.; Khazaradze, G.; Lied, Karstein; Suriñach, E. (Journal article, 2004)
      The main question of the given work is whether the propagation speed of snow avalanches can be determined using seismic observations. The significance of having at least an order of magnitude estimate of this basic physical ...
    • A comparison of avalanche models with data from dry-snow avalanches at Ryggfonn, Norway 

      Issler, Dieter; Harbitz, Carl Bonnevie; Kristensen, Krister; Lied, Karstein; Moe, Arne; Barbolini, M.; Khazaradze, G.; McElwaine, J.N.; Mears, A.I.; Naaim, M.; Sailer, R. (Chapter, 2005)
      Twelve well-documented dry-snow avalanches from the instrurnented Ryggfonn path in western Norway were selected for back-ca1culations with several dynamical avalanche models. In each case, the run-out distance, the front ...
    • Determinación de la velocidad de avalanchas de nieve mediante datos sísmicos 

      Vilajosana, I.; Suriñach, E.; Khazaradze, G.; Gauer, Peter (Chapter, 2006)
      Seismic instrumentation has proved to be a reliable tool for snow avalanche detection. In this approach, besides the detection skills of our system we pretend to go one step further. We aim to infer a physical parameter ...
    • Snow avalanche energy estimation from seismic signal analysis 

      Vilajosana, I.; Suriñach, E.; Khazaradze, G.; Gauer, Peter (Journal article, 2007)
      A method to determine the dissipated seismic energy into the ground by a down going avalanche is presented. Evaluation of the seismic energy is useful for avalanche size classification, model validation, and for characterization ...
    • Snow avalanche speed determination using seismic methods 

      Vilajosana, I.; Khazaradze, G.; Suriñach, E.; Lied, Erik; Kristensen, Krister (Journal article, 2007)
      We present a new method to determine the average propagation speed of avalanches using seismic techniques. Avalanche propagation speeds can reach 70 m/s and more, depending on a wide range of factors, such as the characteristics ...
