<strong>International</strong> <strong>Symposium</strong> on Mitigative Measures against Snow Avalanches
Egilsstaðir, Iceland, March 11–14, 2008
Number of houses in Torrent zones 798 (Red) 17 104 (Yellow)
To show how the endangered houses are distributed, one needs to look at the number of
communities with buildings in Red hazard zones.
Table 2 Number of communities in Tyrol with buildings in Red hazard zones.
Total Number of communities in Tyrol 279
Number of communities with buildings in Red avalanche hazard zones 75
Number of communities with buildings in Red torrent hazard zones 141
Number of communities with buildings in both Red avalanche and torrent zones 46
167 383 (87% ) of the
buildings are situated
outside of
hazard zones

3.1 Socio economic development
There is no doubt that rapid change will take place within the Alpine living space in the next
decades. Reiter (2005) describes three possible scenarios as to how the Alps could be found in
2040. There is an excessive lifestyle scenario (Cool Mountain) compared with an Alpine
wellness scenario and a high risk scenario (Intra Muros) caused by high temperature increase
and therefore destabilisation of mountain slopes.
