Géohistoire du risque d'avalanche dans le Massif vosgien : Réalité spatio-temporelle, cultures et représentations d'un risque méconnu

Abstract : In spite of regular accidents, the medium-high mountain doesn’t seem to play a major role in the study of avalanche. Therefore, the main goal of this thesis is to emphasize the reality of the avalanche risk in the Vosges Mountains by an interdisciplinary approach. Considering risk itself as a social construction, we suggest to study at first the cultures of avalanche risk and then pursue with its material reality (diachronic approach, spatialization, risk occurrence and conditions of emergence). So as to establish if the different protagonists involved in the process of risk construction recognize and appropriate the avalanche risk, we have analyzed the statements of the persons in charge of those events and conducted two different surveys (inductive interviews and a questionnaire). In the end, there is a lack of knowledge and collective memory, and the risk of avalanche seems not to be considered and identified as a real problem. At the very best, it is pointed out as an occasional and localized danger, to which people do not really feel vulnerable.At the same time, through a geo-historical approach, we studied the spatial and temporal distribution of avalanches over the last two centuries and tried to identify the natural and social factors interacting in the risk production system. It appears that, if knowledge concerning avalanches is based on historical sources, their dynamic is strongly conditioned by past and current human activities. Despite the frequency of avalanches, this risk does not appear as a fundamental element of the mountain cultures in the Vosges range and requires measures to draw the attention of people and inform them about it.
