摘要

Knowledge of the spatial and temporal occurrence of avalanche activity is critical for avalanche forecasting and hazard mapping. We present an automatic avalanche monitoring system for Norway. Our system enables us to monitor the release of large avalanches daily. The system monitors the forecasting regions of the Norwegian Avalanche Warning Service continuously throughout the winter. We apply our...
