Every country is exposed to a wide variety of natural hazards, often leading to
substantial loss of life, damage to property or infrastructure. The number of natural hazards
with devastating consequences is increasing especially in mountainous regions, as they are
the most sensitive to human and climatic influences (Hurni et al., 2006). For example, the
seismic risk in Switzerland may increase as a result of the more intensive settlement and
economic harnessing of alpine regions. The assessment of the different hazards through
advanced technology is promoted in order to serve as input for all measures of risk
mitigation.
