Debris flows are a major threat in many parts of the Alps, where they repeatedly cause severe damage to infrastructure and transportation corridors or even loss of life. Nonetheless, the spatial behavior of past debris-flow activity and the analysis of areas affected during particular events have been widely neglected in reconstructions so far. It was therefore the purpose of this study to...

Three major rainfall events have caused considerable damage in the Valais region (Swiss Alps) since 1987. While important debris flows originating from periglacial environments were recorded during the August 1987 and September 1993 rainfall events, no debris flows occurred in October 2000. This paper aims at putting these large area events and the apparent increase in debris flow frequency into...

La dendrochronologie a été utilisée pour étudier 25 ans d’activités de chutes de pierres sur le versant boisé de Täschgufer, à Täsch (Alpes suisses). Une nouvelle approche, basée sur l’apparition de tissu calleux et de canaux résinifères résultant d’impacts dus à des chutes de pierres, permet de déterminer la saison des événements. Les résultats issus de l’analyse de...
