| Summary: | Graz, Austria, has been run for starting zones in the mountain above the village Siglufjörður, northern Iceland. The runs are intended to shed light on the following aspects of the avalanche hazard situation in the village: 1. The shortening of avalanche runout due to lateral spreading of avalanches. This is particularly relevant for the unconfined and partly convex slopes of the Hafnarhyrna and Gróuskarðshnjúkur ridges and also for avalanches that flow from the narrow Strengsgil gullies onto comparatively unconfined runout zones. 2. The difference in runout between avalanches from the main depressions Jörundarskál and Fífladalir compared with avalanches from other parts of the slope with a smaller snow accumulation potential, due to the different sizes of the starting zones and different degree of lateral spreading. 3. The direction of the main avalanche tongues from the starting areas that have been defined in the mountain as a part of the hazard zoning. 4. The shape of the main avalanche tongues from the gullies. 5. The effectiveness of the recently built deflecting dams below Jörundarskál and Strengsgil for |
