AbstractAn integrated mass movement monitoring system including ground and satellite observations has been developed for an active coastal rockslide threatening a railroad at Gascons, in the Gaspé Peninsula, Québec, Canada. The slide consists of an overall wedge failure, involving a volume of 560 000 m³, composed of multiple compartments that are more or less well individualized. A first hypothesis to define boundaries of the blocks forming the sliding mass is proposed and discussed. Displacements of up to 71.5mm/year are measured. Fine analysis of the kinematic behaviour of the slide will lead to a better evaluation of risk associ-ated with this active rockslide and to the implementation of warning criteria.
