ABSTRACT: The Thompson River Valley, located in southern British Columbia, Canada, forms a vital artery of the national transportation network. Main lines of both the Canadian Pacific Railway and the Canadian National Railway are located in this corridor, providing a strategic connection between Canada’s shipping ports on the west coast and the continent’s resources and population to the east. Twelve large landslides extend along a treacherous 10 kilometer reach of the Thompson River Valley south of Ashcroft, British Columbia, and are collectively known as the Ashcroft Thompson River landslides. While the Ashcroft Thompson River Landslides today are typically slow moving, several rapid to very rapid catastrophic failures have occurred in the past 120 years. This paper focuses on the dynamic relationship between the landslides and the surrounding environment, examining the role that climate may play in triggering the slope movements. It is hoped that a better understanding of climatic influences on landslide activity will facilitate early-warning of impending landslides and empower all stakeholders to improve their level of understanding and ability to prepare for, and cope with, the potential impacts of a large landslide.
RÉSUMÉ: La vallée de la rivière Thompson, situé dans le sud de la Colombie-Britannique, au Canada, constitue une artère vitale du réseau de transport national. Grandes lignes à la fois du Chemin de fer Canadien Pacifique et le Canadien National se trouvent dans ce couloir, offrant une connexion stratégique entre les ports maritimes du Canada sur la côte ouest et les ressources et la population du continent à l'est. Douze grands glissements de terrain s'étendent le long d'une perfide 10 km la portée de la vallée de la rivière Thompson sud d'Ashcroft, Colombie-Britannique, et sont collectivement connus comme les glissements de terrain Ashcroft de la rivière Thompson. Alors que les Ashcroft rivière Thompson glissements de terrain sont aujourd'hui généralement lent, plusieurs de défaillances catastrophiques très rapides rapides ont eu lieu dans les 120 dernières années. Cet article se concentre sur la relation dynamique entre les glissements de terrain et l'environnement, en examinant le rôle que peut jouer le climat dans le déclenchement des mouvements de terrain. Il est à espérer qu'une meilleure compréhension des influences climatiques sur l'activité des glissements de terrain facilitera alerte de glissement de terrain imminents et permettre à tous les intervenants afin d'améliorer leur niveau de compréhension et la capacité de se préparer et faire face, les impacts potentiels d'un important glissement de terrain.
