| Zusammenfassung |
| Italy’s 2009-2010 winter season was one of the worst since 1986: the mean value of victims
had almost doubled. AINEVA’s data bank registered 120 avalanche accidents and 217 people
caught, 45 victims, 48 injured, 123 unharmed. In 58This work gives a statistical analysis of
avalanche accidents situation for the winter season 2009-2010 on the southern side
of the Alps, with respect to types of accidents and caught categories, methods of
detection of buried victims, survival percentages and main morphometric values
of detached avalanches - such as slope gradient, aspect, elevation by geographic
area. Results are compared with similar papers for the northern Alps and statistic
values of past seasons. Finally this work analyses the relationship between avalanche
accidents, snow cover average values and meteorological evolution. During the period
29th January – 07th February 2010, frequent but small snowfalls, often combined
with strong winds activity and low mean temperatures broken up by short mild
periods, led to the evolution of a weak snow cover, characterized by wind slab
covering weak layers (depth and surface hoars). It is clearly possible to correlate such
instability with at least five short periods of avalanche accidents occurrence along the
southern side of the Alps as well as along the northern one (Austria, Switzerland and
France). |
