Abstract	RESUME On retrouve des parcs a residus miniers aux quatre coins du globe. Des digues peripheriques servent a retenir les residus miniers produits de l’extraction des mineraux. Ces digues peuvent atteindre une hauteur superieure a une centaine de metres et s’etendre sur plusieurs kilometres. Les digues sont souvent elles-memes constituees de residus miniers grossiers. Dans l’eventualite de la rupture d’une de ces digues, les consequences sur les plans humains, environnementaux, economiques et sociaux peuvent etre tres grandes en raison des quantites de materiaux relâches dans l’environnement. L’activite sismique est reconnue comme etant l’une des causes majeures de ces ruptures.----------ABSTRACT Tailings impoundment facilities are located around the globe. The structures store the fine-grained tailings that are produced by the ore extraction. The height of tailings dams can reach over 100 meters and impoundments can span kilometers. The retention dikes are often made of the coarse fraction of the tailings themselves. The large amounts of materials contained in tailings impoundments render the possible consequences of a rupture and tailings flow catastrophic. Seismic activity is one of the causative factors of tailings impoundment failure.
