ACOUSTIC EMISSIONS IN THE INVESTIGATION OF AVALANCHES

Over the past several years we have been investigating the role of acoustic emissions in the deformation and failure of snow. Our investigations began in the laboratory by studying the acoustical activity associated with snow subjected to various states of stress. With the experience and knowledge gained from our laboratory work, the authors have been able to apply acoustical emission techniques in the field to investigate the stability of avalanche prone snow slopes. For the purpose of this paper we will describe in general terms the methods and equipment used in our investigation and some of the results we have obtained to date. Although we are working with snow, many of the processes involved in the failure of snow slopes should relate directly to the failure of soil and rock slopes.
