| Summary: | Graz, Austria, has been run for starting zones in the mountains above the villages Ísafjörður and Hnífsdalur, northwestern Iceland. The runs are intended to shed light on the following aspects of the avalanche hazard situation in the villages: 1. The effect of the ridge Seljalandsmúli on the flow of avalanches that are released from Seljalandshlíð to the west of the farm Seljaland. 2. The shortening of avalanche runout due to lateral spreading of avalanches. This is particularly relevant for the largely unconfined and partly convex slopes of Gleiðarhjalli below the shelf at 400-500 m a.s.l. 3. The direction of the main avalanche tongues from the starting areas that have been defined in the mountains as a part of the hazard zoning, in particular the influence of the gullies Hraunsgil, Traðargil and Búðargil on the direction of avalanches in the runout area on the northern side of Hnífsdalur. The results of the runs will be used in the delineation of the hazard zones for the villages. Similar results have previously been used for the same purpose for the villages Bolungarvík, Neskaupstaður, Siglufjörður, Seyðisfjörður and Eskifjörður (Jóhannesson et al., 2001a,b, 2002a,b).
