Accidents and economic damage due to snow avalanches and landslides in Iceland Table 4. Direct loss and cost of rescue and relief operations 1974–2000. – Efnahagslegt tjón og kostnaður við björgunaraðgerðir 1974–2000. AmountType of accident (billion IKR) (million USD) Snow avalanches, excl. ski areas, power lines etc. 3.00 37.4 Damages in ski areas 0.17 2.1 Infrastructure, such as power lines 0.07 0.9 Damages due to landslides 0.09 1.1 Total 3.3 41 information from the Ministry for the Environment for the Súðavík and Flateyri accidents in 1995 and on a rough estimate for other accidents in towns and villages. The largest costs are due to the acci- dents in Neskaupstaður (1974), Patreksfjörður (1983), Ólafsvík (1984, 1995), Ólafsfjörður (1988), Seyðis- fjörður (1989, 1992, 1995), Ísafjörður (1994, 1995), Súðavík (1995), Flateyri (1995) and Bolungarvík (1999) (Figure 1). Insurance payments prior to 1983, other than for Neskaupstaður in 1974, were not avail- able for this study and are therefore not included. Fur- thermore, the percentage of the loss which is borne by the owner (typically about 5% for private build- ings) is not included. The loss estimate includes dam- age due to avalanches in rural areas (damages to farm buildings, power and telephone lines and ski lifts), but not operational costs associated with such acci- dents. The unaccounted insurance costs before 1983, the cost borne by the owners of damaged property, and operational costs in rural areas may be roughly esti- mated as 500 million IKR (6.2 million USD) and are therefore much smaller than the total loss estimated in Table 4. The loss due to the disruption of the local society following an avalanche accident is not explicitly esti- mated here. It involves a more or less total disruption of all ordinary activity in a society of several hundred people for several weeks. It also involves a prolonged recovery period where a significant proportion of the society is absorbed in planning the recovery, partici- pating in rebuilding of damaged property and taking part in other activities connected with the accident. COST OF PROTECTION MEASURES After the avalanches in 1995, a government fund that finances protection measures in the threatened areas was strengthened considerably. The Icelandic Avalanche Fund finances up to 90% of the cost of pro- tection measures for avalanche and landslide hazard. The remaining 10% are borne by the local community, except that communities which need comparatively costly measures relative to their size can apply for ad- ditional support from the government. A report was compiled in 1996 about the need for avalanche protec- tion measures in Iceland (Jóhannesson et al., 1996). Based on this report, the local communities together with the Ministry of the Environment made a plan for the construction of protection measures where the communities agreed beforehand on the priorities of the different areas under consideration. The cost of the construction of avalanche defence structures and relocation in endangered areas since the catastrophic accidents in 1995 is summarised in Table 5 (August 2000 price levels and USD exchange rate). In addition to the projects listed in Table 5, ap- praisals of avalanche protection measures have been carried out for Seljalandshlíð in Ísafjörður (Hnit and NGI, 1996), the Bjólfur area in Seyðisfjörður (VA and NGI, 1998), Geirseyrargil in Patreksfjörður (VST and NGI, 1998), the settlement of Bolungarvík (Orion, VA and NGI, 1999) and for Siglufjörður north of Strengsgil (Margreth, 2001), but construction of de- fence structures has not been started in these areas.
